Fault criteria:
| When input voltage exceeds 25.5 V. |
Dependent:
System reaction to a fault:
OK report:
| Fault criteria NOT fulfilled for 2 s with engine running. |

| Type III without Check Engine. |
| (See section Fault handling III, "Other emission-related components and functions" for more information.) |
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.
