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