SPECIAL TOOLS

CAUTION:
^ Disconnect the battery before removing and installing the Central Timer Module (CTM).
^ Be careful when probing the fuse junction panel, power distribution box or any connectors. Damage will result to the connector receptacle if the probe or terminal being used is too large.

NOTE:
^ Diagnostic Trouble Codes (DTCs) will be cleared from the CTM when the battery is disconnected.
^ If DTCs are recorded and the symptom is not present when performing the pinpoint tests, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
