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 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.
^ Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
^ Do not handle the wiper motor abusively when diagnosing the wiper operations. Failure to follow this caution may result in damage to the motor magnets and will make the wiper motor inoperative. Rough handling of new replacement wiper motors may also damage the motor magnets.
