Power Mirror System: Testing: Notes
NOTE:
Before performing following tests, ensure circuit ground, circuit harness wiring and circuit fuse are okay. Also, ensure all circuit connections are clean and tight.
NOTE:
For testing of heated mirrors, see REAR WINDOW & MIRROR
DEFOGGERS article.
NOTE:
To identify connectors and wire colors, see WIRING DIAGRAMS
.
CAUTION:
To prevent damage to terminals, Connector Test Adaptor Kit (J-35616-A) must be used whenever a diagnostic procedure requires checking or probing terminals. To locate and identify terminals, see WIRING DIAGRAMS
.
NOTE:
Using scan tool, check for DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES (DTCS)
under SELF-DIAGNOSTICS. If DTCs exist, perform appropriate DTC test. See POWER MIRROR DTCS
table. If no DTCs exist, perform appropriate symptom test. After repair is complete, clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES (DTCS)
under SELF-DIAGNOSTICS. Recheck system operation.
