Diagnostic trouble code (DTC) information REM -6A07

Condition 

The rear electronic module (REM) uses a number of relays to control the lock units in the rear doors for locking and unlocking.

The rear electronic module (REM) also activates the child-proof lock. A switch in the lock unit indicates that the child-proof lock is activated. The switch provides a ground when the lock motor is in the locked position.

The diagnostic trouble code (DTC) is stored if the rear electronic module (REM) detects that the child-proof lock in one of the rear doors indicates that the child-proof lock is unlocked when it should be locked.

The diagnostic trouble code (DTC) can be diagnosed when the child-proof lock is activated.
