Test C: A Single Mirror Does Not Function With Switch Logic
PINPOINT TEST C: A SINGLE MIRROR DOES NOT FUNCTION WITH SWITCH LOGICNormal Operation
The exterior mirror switch controls the LH exterior mirror movement by switching voltage and ground to circuits 540 (RD), 541 (DB) and 542 (YE). The exterior mirror switch controls the RH exterior mirror movement by switching voltage and ground to circuits 542 (YE), 543 (DG) and 544 (VT).
Mirror Movement
- When the LH/RH exterior mirror motor receives ground through circuit 540 (RD)/543 (DG) and power through circuit 542 (YE), the LH/RH exterior mirror motor will operate left.
- When the LH/RH exterior mirror motor receives power through circuit 540 (RD)/543 (DG) and ground through circuit 542 (YE), the LH/RH exterior mirror motor will operate right.
- When the LH/RH exterior mirror motor receives ground through circuit 541 (DB)/544 (VT) and power through circuit 542 (YE), the LH/RH exterior mirror motor will operate downward.
- When the LH/RH exterior mirror motor receives power through circuit 541 (DB)/544 (VT) and ground through circuit 542 (YE), the LH/RH exterior mirror motor will operate upward.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Exterior mirror control switch
- Exterior mirror motor
- Exterior mirror
