On-board diagnosis
Enable criteria:
- Ignition ON.
Fault criteria:
- No communication with CIM for 1.25 s.
System reaction to a fault:
- No TCS/ESP function
Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
Diagnostic help
- In order to read DTC from TCS/ESP, communication with CIM is required. If the DTC is stored and read with the diagnostic instrument, it indicates intermittent bus lead fault.
