On-board diagnosis
Type of diagnosis:
Enable criteria:
| The following diagnostic trouble codes may not be generated: |
Fault criteria:
| When input voltage is below 0.21V for more than 0.6 seconds. |
Dependent:
System reaction to a fault:
| The control module uses 0°C as a substitute value. |
OK report:
| Input conditions fulfilled without a fault reported. |
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. |
