Warning Devices

The Central Timer Module (CTM) is equipped with a self-diagnostic feature. This feature will allow you to actuate four of the CTM outputs. Actuate the outputs one at a time in the following order:
^ Turn the wipers on low speed
^ Illuminate the heated rear window switch indicator
^ Illuminate the interior lamp
^ Illuminate the safety bell warning indicator in the instrument cluster

To prepare the vehicle for the self-diagnostic mode turn the windshield wiper switch to the low speed position, interior lamp to the 12 SEC position and close both doors. To enter the self diagnostic feature of the CTM hold the heated rear window switch while turning the ignition key to the on position, then release the heated rear window switch. The CTM is now in self-diagnostic mode and waiting for a command to activate the four outputs. Use the heated rear window switch to turn on and then off each of the four CTM outputs.

To exit the self-diagnostic mode, turn the ignition key off.
