• During acceleration the knock sensor retard system is designed only for emergencies the basic ignition timing is programmed within the anti knocking zone if recommended fuel is used under dry conditions the retard system does not operate under normal driving conditions if engine knocking occurs the knock sensor monitors the condition the signal is transmitted to the ecm the ecm retards the ignition timing to eliminate the knocking condition 36
• During warm up 36
• Electronic ignition ei system 36
• Engine control system 36
• Firing order 1 3 4 2 the ignition timing is controlled by the ecm to maintain the best air fuel ratio for every running condition of the engine the ignition timing data is stored in the ecm the ecm receives information such as the injection pulse width and camshaft position sensor signal comput ing this information ignition signals are transmitted to the power transistor during the following conditions the ignition timing is revised by the ecm according to the other data stored in the ecm 36
• Fuel cut control at no load and high engine speed 36
• Fuel is injected simultaneously into all four cylinders twice each engine cycle in other words pulse signals of the same width are simultaneously transmitted from the ecm the four fuel injectors will then receive the signals two times for each engine cycle this system is used when the engine is being started and or if the fail safe system cpu is operating 36
• Fuel shut off 36
• Fuel to each cylinder is cut off during deceleration or operation of the engine at excessively high speeds or operation of the vehicle at excessively high speeds 36

• Introduction 47
• On board diagnostic obd system 47
• The above information can be checked using procedures listed in the table below 47
• The ecm has an on board diagnostic system which detects malfunctions related to engine sensors or actua tors the ecm also records various emission related diagnostic information including 47
• The malfunction indicator mi on the instrument panel lights up when the same malfunction is detected in two consecutive trips two trip detection logic or when the ecm enters fail safe mode refer to ec 81 47
• The trip in the two trip detection logic means a driving mode in which self diagnosis is performed during vehicle operation specific on board diagnostic items will cause the ecm to light up or blink the mi and store dtc and freeze frame data even in the 1st trip as shown below 47
• Two trip detection logic 47
• When there is an open circuit on mi circuit the ecm can not warn the driver by lighting up mi when there is a malfunction on engine control system therefore when electrical controlled throttle and part of ecm related diagnoses are continuously detected as ng for 5 trips ecm warns the driver that engine control system has malfunction and mi circuit is open by means of operating fail safe function 47

• Emission related diagnostic information 48
• Emission related diagnostic information items 48
• On board diagnostic obd system 48
• The fail safe function also operate when above diagnoses except mi circuit are detected and demands the driver to repair the malfunction 48
• Cr with euro obd 49
• Dtc and 1st trip dtc 49
• On board diagnostic obd system 49
• The 1st trip dtc whose number is the same as the dtc number is displayed for the latest self diagnostic result obtained if the ecm memory was cleared previously and the 1st trip dtc did not reoccur the 1st trip dtc will not be displayed if a malfunction is detected during the 1st trip the 1st trip dtc is stored in the ecm memory the mi will not light up two trip detection logic if the same malfunction is not detected in the 2nd trip meeting the required driving pattern the 1st trip dtc is cleared from the ecm memory if the same malfunction is detected in the 2nd trip both the 1st trip dtc and dtc are stored in the ecm memory and the mi lights up in other words the dtc is stored in the ecm memory and the mi lights up when the same malfunction occurs in two consec utive trips if a 1st trip dtc is stored and a non diagnostic operation is performed between the 1st and 2nd trips only the 1st trip dtc will continue to be stored for malfunctions that blink or light up the mi during the 1st tr 49

• Freeze frame data and 1st trip freeze frame data 50
• How to read dtc and 1st trip dtc 50
• On board diagnostic obd system 50
• Cr with euro obd 51
• For example the egr malfunction priority 2 was detected and the freeze frame data was stored in the 2nd trip after that when the misfire priority 1 is detected in another trip the freeze frame data will be updated from the egr malfunction to the misfire the 1st trip freeze frame data is updated each time a different mal function is detected there is no priority for 1st trip freeze frame data however once freeze frame data is stored in the ecm memory 1st trip freeze data is no longer stored because only one freeze frame data or 1st trip freeze frame data can be stored in the ecm if freeze frame data is stored in the ecm memory and freeze frame data with the same priority occurs later the first original freeze frame data remains unchanged in the ecm memory both 1st trip freeze frame data and freeze frame data along with the dtcs are cleared when the ecm mem ory is erased procedures for clearing the ecm memory are described in ec 57 how to erase emis sion related diagnostic information 51
• On board diagnostic obd system 51
• Srt item 51
• System readiness test srt code 51
• System readiness test srt code is specified in service 01 of iso 15031 5 as part of an enhanced emissions test for inspection maintenance i m certain states require the status of srt be used to indicate whether the ecm has completed self diagnosis of major emission systems and com ponents completion must be verified in order for the emissions inspection to proceed if a vehicle is rejected for a state emissions inspection due to one or more srt items indicating incmp use the information in this service manual to set the srt to cmplt in most cases the ecm will automatically complete its self diagnosis cycle during normal usage and the srt status will indicate cmplt for each application system once set as cmplt the srt status remains cmplt until the self diagnosis memory is erased occasionally certain portions of the self diagnostic test may not be completed as a result of the customer s normal driving pattern the srt will indicate incmp for these items note the srt will also indicate inc 51
• The table below shows required self diagnostic items to set the srt to cmplt 51
• Cr with euro obd 52
• If the 1st trip dtc is erased all the srt will indicate incmp note srt can be set as cmplt together with the dtc s therefore dtc check must always be carried out prior to the state emission inspection even though the srt indicates cmplt 52
• On board diagnostic obd system 52
• Srt is set as cmplt after self diagnosis has been performed one or more times completion of srt is done regardless of whether the result is ok or ng the set timing is different between ok and ng results and is shown in the table below 52
• Srt set timing 52
• The emissions inspection requires cmplt of the srt only with ok self diagnosis results 52
• The srt will indicate cmplt at the time the respective self diagnoses have one 1 ok result 52
• When all srt related self diagnoses showed ok results in a single cycle ignition off on off the srt will indicate cmplt case 1 above when all srt related self diagnoses showed ok results through several different cycles the srt will indicate cmplt at the time the respective self diagnoses have at least one ok result case 2 above if one or more srt related self diagnoses showed ng results in 2 consecutive cycles the srt will also indi cate cmplt case 3 above the table above shows that the minimum number of cycles for setting srt as incmp is one 1 for each self diagnosis case 1 2 or two 2 for one of self diagnoses case 3 however in preparation for the state emissions inspection it is unnecessary for each self diagnosis to be executed twice case 3 for the following reasons 52
• When during srt driving pattern 1st trip dtc ng is detected prior to cmplt of srt the self diagno sis memory must be erased from ecm after repair 52

• The engine is started at the engine coolant temperature of 10 to 35 c 14 to 95 f where the voltage between the ecm terminal 72 and ground is 3 4 v 56
• The engine must be operated at idle speed until the engine coolant temperature is greater than 70 c 158 f where the voltage between the ecm terminal 72 and ground is lower than 1 v pattern 2 56
• The following is the information specified in service 06 of iso 15031 5 the test value is a parameter used to determine whether a system circuit diagnostic test is ok or ng while being monitored by the ecm during self diagnosis the test limit is a reference value which is specified as the maximum or minimum value and is compared with the test value being monitored these data test value and test limit are specified by test id tid and component id cid and can be dis played on the gst screen 56
• The time required for each diagnosis varies with road surface conditions weather altitude individual driv ing habits etc zone a refers to the range where the time required for the diagnosis under normal conditions is the shortest zone b refers to the range where the diagnosis can still be performed if the diagnosis is not completed within zone a normal conditions refer to the following 56
• When steady state driving is performed again even after it is interrupted each diagnosis can be con ducted in this case the time required for diagnosis may be extended 1 depress the accelerator pedal until vehicle speed is 90 km h 56 mph then release the accelerator pedal and keep it released for more than 10 seconds depress the accelerator pedal until vehicle speed is 90 km h 56 mph again 2 checking the vehicle speed with gst is advised 56

• The ecm activates the fuel pump for several seconds after the ignition switch is turned on to improve engine startability if the ecm receives a engine speed signal from the crankshaft position sensor pos and cam shaft position sensor phase it knows that the engine is rotating and causes the pump to operate if the engine speed signal is not received when the ignition switch is on the engine stalls the ecm stops pump operation and prevents battery discharging thereby improving safety the ecm does not directly drive the fuel pump it controls the on off fuel pump relay which in turn controls the fuel pump 750

• The mi is located on the instrument panel 1 the mi will light up when the ignition switch is turned on without the engine running this is a bulb check if the mi does not light up refer to di 32 warning lamps or see ec 1596 mi data link connectors 2 when the engine is started the mi should go off if the mi remains on the on board diagnostic system has detected an engine system malfunction 1268
• The on board diagnostic system has the following four functions 1268
• When there is an open circuit on mi circuit the ecm cannot warn the driver by lighting up mi when there is malfunction on engine control system therefore when electrical controlled throttle and part of ecm related diagnoses are continuously detected as ng for 5 trips ecm warns the driver that engine control system malfunctions and mi circuit is open by means of operating fail safe function the fail safe function also operates when above diagnoses except mi circuit are detected and demands the driver to repair the malfunction 1268
