Recommended Posts

Behöver hjälp.

Har en Cadillac seville sts 2002. Nedre bromsljusen funkar ej medans bromsljusrampen fungerar.
Har kollar säkring som är okey. lamporna okey, kan det vara relä eller möjligtvis bromsljus switchen som är paj.

Finns det någon som har förslag på i vilken ordning jag ska checka felet.

 

Får också ett felmeddelande på panelen: SERVICE ELECTRIC SYS.
( Börjar bli smått orolig )

 

Får följande felkod

DTC Code: P1574 - Description: Stop Lamp Switch Circuit
Probable Causes:
1. Sensor or solenoid faulty
2. Connector terminal contact is damaged or corroded
3. Wire harness - Check harness for correct voltage, open, short to ground or short to voltage
4. Update control unit software - Check for the latest control unit update
5. Powertrain or Engine Control Module faulty
