Hva betyr feilkoden?

The code indicates an over temperature in connection with the control of the A/C compressor solenoid. The solenoid is driven by an internal power stage in the control module, and the fault concerns the output of that power stage. The code is set when the control module detects the fault with the engine running and the A/C function activated.

Mulige årsaker

Signal line from the engine control module short-circuited to voltage
Damaged solenoid in the A/C compressor
Internal fault in the engine control module

Hva du kan gjøre

1Start the engine, switch on the A/C and test-drive to see whether the fault returns
2Read and clear the fault code, and check that the air conditioning works after the test drive
3Look at the connectors and wiring to the A/C compressor solenoid for loose contacts, oxidation and chafing
4Use a multimeter to check that the signal line from the engine control module has no contact with voltage, with the connectors disconnected
5If the fault remains, have a workshop check the A/C compressor solenoid and the engine control module

Symptomer du kan merke4
