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 control switch uses circuits 940 (DB/OG), 942 (RD/OG), 943 (VT/OG), 944 (DG/OG) and 945 (YE/BK) to control the exterior mirror motor movement. The exterior mirror switch controls the LH exterior mirror motor movement by switching voltage and ground to circuits 940 (DB/OG), 942 (RD/OG) and 945 (YE/BK). The exterior mirror switch controls the RH exterior mirror motor movement by switching voltage and ground to circuits 943 (VT/OG), 944 (DG/OG) and 945 (YE/BK).

Mirror Movement
- When the LH/RH exterior mirror motor receives ground through circuit 940 (DB/OG)/943 (VT/OG) and power through circuit 945 (YE/BK), the LH/RH exterior mirror motor will operate downward.
- When the LH/RH exterior mirror motor receives power through circuit 940 (DB/OG)/943 (VT/OG) and ground through circuit 945 (YE/BK), the LH/RH exterior mirror motor will operate upward.
- When the LH/RH exterior mirror motor receives ground through circuit 942 (RD/OG)/944 (DG/OG) and power through circuit 945 (YE/BK), the LH/RH exterior mirror motor will operate right.
- When the LH/RH exterior mirror motor receives power through circuit 942 (RD/OG)/944 (DG/OG) and ground through circuit 945 (YE/BK), the LH/RH exterior mirror motor will operate left.

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