Fault Code 9131

Fault Code 9131

B+

Diagnostic conditions
- Engine running

Possible cause of fault
- Open circuit of the charge lead between generator and battery (B+)

NOTE: The two voltage values at pin 61 and pin 30 are compared to each other in the instrument cluster. If the voltage value at pin 30 decreases severely compared to pin 61, the battery is not charged when the vehicle is in motion (e.g. open circuit in B+ wire) and fault 9131 is stored.

Affected pins
Instrument cluster connector B, pin 2 and pin 18
