Wiper and Washer Systems: Service Precautions

CAUTION:
- Disconnect the battery before removing and installing the GEM/CTM or its connectors. 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, 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 electrostatic discharges. If exposed to these charges, damage may result.
