Windows: Service Precautions

CAUTION:
^ Electronic modules are sensitive to electrostatic discharges. If exposed to these charges, damage may result.
^ Disconnect the battery before removing and installing the Generic Electronic Module (GEM) or its connectors. Failure to follow this caution will result in the GEM storing many erroneous DTCs and possibly exhibiting erratic operation after installation.
^ Be careful when probing the I/P fuse panel, power distribution box or any connectors. Damage will result to the connector receptacle if the probe or terminal being used is too large.
