Lighting and Horns: Service Precautions

CAUTION:
^ Before removing and installing the GEM/CTM or its connectors, disconnect the battery. Failure to follow this caution will result in the GEM/CTM storing many erroneous DTCs and it may exhibit erratic operation after installation.
^ Be careful when probing the central junction box, battery junction box, or any connectors. Damage will result to the connector receptacle if the probe or terminal being used is too large.
