2. Connect the positive (+) lead from the voltmeter to terminal 3 and the negative (-) lead to terminal 4.
3. Set the door lock manual switch to UNLOCK, check that the voltage rises from 0 volts to battery voltage for approximately 0.2 seconds.







4. Reverse the polarity of the voltmeter leads.
5. Set the door lock manual switch to LOCK, check that the voltage rises from 0 volts to battery voltage for approximately 0.2 seconds.

If operation is not as specified, replace the relay.








INSPECT POWER MAIN RELAY CONTINUITY
