DESCRIPTION:
The following symptoms may occur in freezing conditions:
^ Car can not be locked with remote.
^ Driver information Module (DIM) message indicating one of the doors being open although all doors are closed.
^ Interior light stays on although all doors are closed.
The cause is water ingress and freezing on the cam lever for the ajar-switch in the lock unit, resulting in incorrect function of the ajar-switch.
From breakpoints shown above, extra grease has been introduced around the ajar-switch lever mechanism to avoid water freezing on this switch.
