Pinpoint Test A: The Mirrors are Inoperative - Non-Memory Mirrors

Refer to Wiring Diagram Set 124, Power Mirrors for schematic and connector information. Diagrams By Number

Normal Operation

Under normal operation, the exterior mirror control switch receives voltage through circuit SBP13 (GY/RD) and ground through circuit GD133 (BK). The exterior mirror control switch uses circuit CPM23 (GY) as the common circuit for both exterior mirror motor up/down and right/left movement.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Exterior mirror control switch



PINPOINT TEST A: THE MIRRORS ARE INOPERATIVE - NON-MEMORY MIRRORS

-------------------------------------------------
A1 CHECK THE EXTERIOR MIRROR CONTROL SWITCH


- Disconnect: Exterior Mirror Control Switch C527.
- Carry out the Exterior Mirror Control Switch component test.

- Did the exterior mirror control switch pass the component test?

Yes
GO to A2.

No
INSTALL a new exterior mirror control switch. REFER to Exterior Mirror Control Switch Service and Repair. TEST the system for normal operation.

-------------------------------------------------
A2 CHECK THE VOLTAGE TO THE EXTERIOR MIRROR CONTROL SWITCH - CIRCUIT SBP13 (GY/RD)


- Ignition ON.
- Measure the voltage between exterior mirror control switch C527-3, circuit SBP13 (GY/RD), harness side and ground.




- Is the voltage greater than 10 volts?

Yes
GO to A3.

No
VERIFY Smart Junction Box (SJB) fuse 13 (5A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short. TEST the system for normal operation.

-------------------------------------------------
A3 CHECK CIRCUIT GD133 (BK) FOR AN OPEN


- Ignition OFF.
- Measure the resistance between exterior mirror control switch C527-1, circuit GD133 (BK), harness side and ground.




- Is the resistance less than 5 ohms?

Yes
GO to A4.

No
REPAIR the circuit. TEST the system for normal operation.

-------------------------------------------------
A4 CHECK CIRCUIT CPM23 (GY) FOR A SHORT TO VOLTAGE


- Ignition ON.
- Measure the voltage between exterior mirror control switch C527-6, circuit CPM23 (GY), harness side and ground.




- Is any voltage present?

Yes
REPAIR the circuit. TEST the system for normal operation.

No
GO to A5.

-------------------------------------------------
A5 CHECK CIRCUIT CPM23 (GY) FOR A SHORT TO GROUND


- Ignition OFF.
- Measure the resistance between exterior mirror control switch C527-6, circuit CPM23 (GY), harness side and ground.




- Is the resistance greater than 10,000 ohms?

Yes
REPAIR the open in circuit CPM23 (GY). TEST the system for normal operation.

No
REPAIR the short in circuit CPM23 (GY). TEST the system for normal operation.
