Fault criteria:
| The cause of the fault is a short circuit of the I-bus anywhere in the connecting wiring harness or internally in a connecting control module. |
System reaction to a fault:
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. |
| • | 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. |
