Step 1: Fault Code Readings
Registered fault codes (whether active or inactive) can
quickly point to faults; however, they also can be a
fault-finding aid for the symptom. Freeze frames of
information for specific fault codes may also be helpful for
finding causes for the symptom.
Fault tracing using relevant service information
should always be carried out for relevant fault codes.
Components/functions of special interest:
•
MID 128, Engine ECU
PID 84 Vehicle speed
PID 91 Accelerator pedal
