Signal Faulty. Permanent Fault

Signal faulty. Permanent fault

Checking the connectors








- Ignition off.
- Check rear electronic module (REM) and left and right boot lighting connector for contact resistance and oxidation as described in Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault and loose contact as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check especially for damage.
- Do the necessary corrective action.
- Install the components, connect the connectors, etc.
- Ignition on.
Read the status of the diagnostic trouble code.
If the status is now intermittent, fault was caused by a poor contact in the connectors.

Additional information:
- To access the boot lighting, see Bulb, cargo compartment lighting, replacing Service and Repair
- To disconnect the rear electronic module connector (REM), see Integrated relay/fusebox cargo compartment/Rear electronic module (REM), replacing Integrated Relay/Fusebox Cargo Compartment/Rear Electronic Module (REM), Replacing.
