DPMS (Door Multiplex Control Unit) Input Test

1. Turn the ignition switch to LOCK (0).

1. Remove the power window master switch.
   NOTE: Be careful not to scratch the door trim.

1. Disconnect the 37P connector (A) from the power window master switch (B).

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 5 .

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 all the input tests prove OK, go to Step 6 .

   - Faulty LED
   - Poor ground (G501)
   - An open in the wire

   26

   PNK

   Ignition switch ON (II)

   Connect the No. 14 and No. 26 terminals:The driving position memory switch lights should come on.

   - Faulty driving position memory switch

   [ ]: | RHD model

1. Reconnect the connector to the power window master switch, and make these input tests at the connector.
   - If any test indicates a problem, find and correct the cause, then recheck the system.
   - If all the input tests prove OK, the door multiplex control unit must be faulty; replace the power window master switch.
   NOTE: After replacing the power window master switch, reset the power window control unit.
