Electrical System Testing

Ignition ON and the engine OFF, command each VLOM solenoid ON and OFF using the scan tool. Standing next to the engine compartment, you should be able to hear the solenoid energize and de-energize with each command.

• If you cannot hear each solenoid energize and de-energize, then refer to DTC P3401, P3425, P3441, or P3449 .
