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 Module (DDM) or Passenger Door Module (PDM) controls the mirror horizontal and vertical motors through the use of bi-directional motor controls. When the mirror is commanded up and down, voltage or ground is supplied to the mirror vertical motor through the mirror motor vertical control circuit and voltage or ground is supplied through the mirror motor common control circuit.
Horizontal controls operate in the same manner with the mirror motor horizontal control circuit supplying voltage or ground and the mirror motor common control circuit suppling voltage or ground to the mirror horizontal motor when the mirror is commanded right and left.
Battery voltage must be between 9-16 volts.
An improper voltage level is detected on the driver/passenger mirror motor common control circuit while the mirror is being commanded.
An improper voltage level is detected on the driver/passenger mirror motor vertical control circuit while the mirror is being commanded.
An improper voltage level is detected on the driver/passenger mirror motor horizontal control circuit while the mirror is being commanded.
Mirror movement is suspended as 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 fault free ignition cycles. |

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