Keyless/Power Door Locks/Security System (Driver's and Passenger's MICU, Door Multiplex Control Unit, and Front Passenger's Power Window Switch) Input Test

Front Passenger's Power Window Switch

1. Turn the ignition switch to LOCK (0), and remove the front passenger's power window switch.

1. Disconnect the 37P connector from the front passenger's power window switch.

1. Inspect the connector and socket terminals to be sure they are all making good contact.
   - If the terminals are bent, loose, or corroded, repair them as necessary and recheck the system.
   - If the terminals look OK, go to Step 20 .

1. With the connector still disconnected, make these input tests at the connector.
   - If any test indicates a problem, find and correct the cause, then recheck the system.
   - If the input test proves OK, go to Step 21 .

   BLK

   Under all conditions

   Check for continuity to ground: There should be continuity.

   - Poor ground (G505)
   - An open in the wire

   Front passenger's door lock knob switch in UNLOCK

   Measure the voltage to ground: There should be less than 1 V.

   - Poor ground (G505)
   - Faulty front passenger's door lock knob switch
   - An open in the wire

   Front passenger's door lock knob switch in LOCK

   Measure the voltage to ground: There should be 5 V or more.

   - Faulty front passenger's door lock knob switch
   - A short to ground in the wire

1. If multiple failures are found on more than one control unit, replace the driver's under-dash fuse/relay box (includes the driver's MICU). If input failures are related to a particular control unit, replace the control unit.
