4
INSPECT POSITION MEMORY CONTROL MODULE CIRCUIT FOR OPEN CIRCUIT
•  Position memory control module and mirror position sensor connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Mirror position sensor terminal 2A—Position memory control module terminal 2F
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for possible open circuit, then go to the next step.
