Pinpoint Test 3

PINPOINT TEST 3: A SINGLE MIRROR DOES NOT FUNCTION WITH SWITCH LOGIC

Step 1 - 2:









Normal Operation
The exterior mirror control switch uses circuits (R), (DL), (Y), (DG) and (V) to control the exterior rear view mirror movement.
- When power is directed through circuits (R) and (DG) and ground through circuit (Y), the LH/RH exterior rear view mirror will operate left.
- When ground is directed through circuits (R) and (DG) and power through circuit (Y), the LH/RH exterior rear view mirror will operate right.
- When power is directed through circuits (DL and /(V) and ground through circuit (Y), the LH/RH exterior rear view mirror will operate down.
- When ground is directed through circuits (DL) and (V) and power through circuit (Y), the LH/RH exterior rear view mirror will operate up.

Possible Causes
- circuit (R) open
- circuit (DL) open
- circuit (Y) open
- circuit (DG) open
- circuit (V) open
- exterior mirror control switch
