- 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
- Two trip detection logic
- 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
- 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
- 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
- The above information can be checked using procedures listed in the table below

- 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
- Cr with euro obd
- The table below shows required self diagnostic items to set the srt to cmplt
- 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
- 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
- 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
- The srt will indicate cmplt at the time the respective self diagnoses have one 1 ok result
- The emissions inspection requires cmplt of the srt only with ok self diagnosis results
- Srt set timing
- 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
- On board diagnostic obd system
- 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
