On-board diagnosis
Type of diagnosis:
Enable criteria:
Fault criteria:
| Voltage is higher than 5,4 V for more than 0,2 s. |
System reaction to a fault:
| Limp Home, engine torque limitation. |
| The control module uses a substitute value for air mass of 800 mg/combustion and an atmospheric pressure of 70 kPa. |
OK report:
| Fault criteria NOT fulfilled for 0.2 s. |
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. |
