Fault Diagnosis: TRIONIC Engine
Management System
Application:
1993- 9000
Many TRIONIC system components which have been replaced are found to be fault-free when subsequently tested. To avoid the unnecessary
replacement of good components, follow the diagnostic guidelines in this PSI. To provide further assistance in diagnosis:
^
If malfunctions occur due to defective components, the cause for the failure must be determined by testing the components as described in the
relevant fault diagnosis instruction.
^
If the fault is of the intermittent type, it could be difficult to determine the cause. Tests with known good replacement components may then be
necessary.
^
If the same fault symptoms occur with the replacement component, the original component must be refitted. For example, changing a control module
following complaints about driveability with no previous fault diagnosis is unacceptable.
^
In many cases, trouble is caused by wiring harness faults, corroded cable terminals, pushed out connector pins, etc.
^
File a copy of this PSI in Service Manual 2:7 TRIONIC Engine Management System M1993 (P/N 03 46 924) to aid in future diagnosis.
