- Check Engine
- Cruise control not working.
- Limp home

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:
- When the ECM is awake, diagnosis is active (even with the ignition off).

Fault criteria:
- When voltage on output exceeds 4.7 V.

Dependent:
- None

System reaction to a fault:
- Correction of mass air flow/combustion for fuel calculation is blocked.
- Limited acceleration and idle function.
- Cruise control blocked.
- Secondary air switched off.

OK report:
- Fault criterion not fulfilled and vehicle speed over 0 km/h for more than 60 s.

Fault handling:
Type III
(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.
