On-board diagnosis
Type of diagnosis:
Enable criteria:
Battery voltage must be between 11 - 16 V. |
Fault criteria:
When voltage on the output exceeds 2.0 V for more than 1 s. |
Dependent:
System reaction to a fault:
Switches off output to A/C relay. |
Engine torque limitation (which is a function of vehicle speed, intake air temperature and number of incorrect fan stages). |
OK report:
Fault criteria NOT fulfilled for 5 s. |
Fault handling:
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.
