Test C: A Single Mirror Does Not Function With Switch Logic - Non-Memory Mirrors

PINPOINT TEST C: A SINGLE MIRROR DOES NOT FUNCTION WITH SWITCH LOGIC - NON-MEMORY MIRRORS

Normal Operation
The exterior mirror switch controls the LH exterior mirror movement by switching voltage and ground to circuits CPM16 (BN/BU), CPM17 (BU/GN) and CPM23 (GY). The exterior mirror switch controls the RH exterior mirror movement by switching voltage and ground to circuits CPM20 (BN/WH), CPM21 (YE/VT) and CPM23 (GY).

- When the LH/RH exterior mirror motor receives power through circuit CPM16 (BN/BU) or CPM20 (BN/WH) and ground through circuit CPM23 (GY), the LH or RH exterior mirror motor will operate right.
- When LH/RH exterior mirror motor receives ground through circuit CPM16 (BN/BU) or CPM20 (BN/WH) and power through circuit CPM23 (GY), the LH or RH exterior mirror motor will operate left.
- When the LH/RH exterior mirror motor receives power through circuit CPM17 (BU/GN) or CPM21 (YE/VT) and ground through circuit CPM23 (GY), the LH or RH exterior mirror motor will operate upward.
- When LH/RH exterior mirror motor receives ground through circuit CPM17 (BU/GN) or CPM21 (YE/VT) and power through circuit CPM23 (GY), the LH or RH exterior mirror motor will operate downward.

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