On-board diagnosis
Type of diagnosis:
Enable criteria:
| Vehicle speed above 30 km/h for more than 30 seconds. |
Fault criteria:
| Radio receiver, left-hand front, short circuited to another radio receiver. |
System reaction to a fault:
| The control module stores the most recently received transfer and uses it for continued functionality. |
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.
Diagnostic help
In case of a fault, the control module may need up to 10 minutes in an active state before it can diagnose the fault.
