Operation CHARM: Car repair manuals for everyone.

Test Note

CAUTION:
^ Disconnect the battery before removing and installing the CTM.
^ 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 electrostatic discharges. If exposed to these charges, damage may result.

NOTE:
^ DTCs will be cleared from the CTM when the battery is disconnected.
^ If DTCs are recorded and the symptom is not present when performing the pinpoint tests, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
