Trouble Diagnosis Introduction

SCOPE OF THIS DOCUMENT
This document presents the trouble diagnosis method applicable to all ECMs with the following specifications:
PREREQUISITES FOR TROUBLE DIAGNOSIS
To begin trouble diagnosis, it is essential to have the following items available:
Documentation Type
Diagnostic procedures:
Assisted with CONSULT-II, Service Manual.
Wiring diagrams.
Special tool required PLUGGED RAIL tools
REMINDERS
Trouble Diagnosis:
There are present DTCs and stored DTCs (which appeared in a certain context and have since disappeared
or which are still present but have not had trouble diagnosis performed on them in the current context).
The “present or “stored” status of DTCs must be considered when activating the diagnostic tool after power is
supplied to the ECM (without activating the system components).
Deal with present DTCs according to the procedure specified in the corresponding DTC trouble diagnosis.
For stored DTCs, note the DTCs displayed and follow the instructions in the Notes section.
If the DTC is confirmed when the instructions in the Notes section are applied, the malfunction is present. Deal
with the DTC.
If the DTC is not confirmed, check:
Electrical lines which correspond to the malfunction
Connectors for these lines (for oxidation, bent pins, etc.)
Resistance of the malfunction component
Condition of the wires (melted or cut insulation, wear)
Conformity Check
The conformity check is designed to check the states and data monitor items which do not display any DTCs
on the diagnostic tool when inconsistent. This phase therefore allows:
Diagnoses malfunctions that do not have a DTC display, and which may correspond to a customer com-
plaint.
Checks that the system is operating correctly and that there is no risk of a DTC reappearing after repairs.
This section gives the trouble diagnosis procedures for states and parameters and the conditions for checking
them.
If a state is not operating normally or a data monitor value is outside permitted tolerance values, you should
consult the corresponding trouble diagnosis page.
Customer Complaints - Trouble Diagnosis
If the test with the CONSULT-II is OK, but the customer complaint still present, the malfunction should be
treated by customer complaints.
Vehicle(s): E11 with K9K
