Wiper and Washer Systems: Service Precautions

CAUTION:
^ Before removing and installing the GEM/CTM or its connectors, disconnect the battery. Failure to follow this caution will result in GEM/CTM storing many erroneous DTCs and it may exhibit erratic operation after installation.
^ Be careful when probing the Battery Junction Box (BJB), Central Junction Box (CJB) or any connectors. Damage will result to the connector receptacle if the probe or terminal being used is too large.
^ Electronic modules are sensitive to electrical charges. If exposed to these charges, damage may result.
