Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
Driver/Passenger Mirror Motor Right Control | B1605 02 | B1605 04 | B1605 01 | -- |
Driver/Passenger Mirror Right/Down Motors Common | B1544 02 | B1544 04 | B1544 01 | -- |
Driver/Passenger Mirror Motor Down Control | B1600 02 | B1600 04 | B1600 01 | -- |
The Driver Door Switch (DDS) or Passenger Door Switch (PDS) controls the mirror horizontal and vertical motors through the use of bi-directional motor controls. When the mirror is commanded up, voltage is supplied to the mirror vertical motor through the Driver/Passenger Mirror Motor Right/Down Motors Common circuit and ground is supplied through the Driver/Passenger Mirror Motor Down Control circuit. When the mirror is commanded down, voltage is supplied to the mirror vertical motor through the Driver/Passenger Mirror Motor Down Control circuit and ground is supplied through the Driver/Passenger Mirror Motor Right/Down Motors Common circuit.
Horizontal controls operate in the same manner with the Driver/Passenger Mirror Motor Right/Down Motors Common circuit supplying voltage and the Driver/Passenger Mirror Motor Right Control circuit supply a ground to the mirror horizontal motor when the mirror is commanded right. When the mirror is commanded left, voltage is supplied to the mirror horizontal motor through the Driver/Passenger Mirror Motor Right Control circuit and ground is supplied through the Driver/Passenger Mirror Motor Right/Down Motors Common circuit.
The power mirror is being commanded left, right, up, or down.
An improper voltage level is detected on the Driver/Passenger Mirror Motor Right/Down Motors Common circuit while the mirror is being commanded.
An improper voltage level is detected on the Driver/Passenger Mirror Motor Down Control circuit while the mirror is being commanded.
An improper voltage level is detected on the Driver/Passenger Mirror Motor Right Control circuit while the mirror is being commanded.
Mirror movement is suspended so long as the fault is present.
• | A current DTC will clear when the fault is no longer present. |
• | A history DTC will clear after 40 malfunction-free ignition cycles. |
Outside Rearview Mirror Schematics
Outside Mirror Description and Operation
Command the left and right outside mirror to move up, down, left and right using the mirror directional switch. The mirror should move in the commanded direction.

⇒ | If less the specified value, test the appropriate control circuit for a short to ground. |
⇒ | If not within the specified range, test both control circuit for an open/high resistance. If the circuits test normal, test or replace the rearview mirror motor. |
⇒ | If not within the specified range, test both control circuit for an open/high resistance. If the circuits test normal, test or replace the rearview mirror motor. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
