On-board diagnosis
Type of diagnosis:
Fault criteria:
| No communication with CIM and TCS/ESP for 1 s. |
OK report:
| Fault criteria NOT fulfilled. |
Checking the wiring harness
| • | Faults in the control module female connector can be the cause of the DTC. Check the connector with respect to oxidation, depressed pins and pin clamping force. |
| • | 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
Communication with CIM is required in order to read the trouble codes from the control module. If the trouble code is stored and read with the diagnostic tool, this is an indication of an intermittent fault in the bus lead.
