Diagnostic Test

TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Turn the turn signal on.
4. Turn the puddle lamps on, if equipped with puddle lamp mirror.
5. Turn the rear defogger on, if equipped with heated mirror.
6. Press and release the Mirror Select switch to select the Driver Outside Rearview Mirror.
7. Operate the Mirror Adjust switch in all directions several times while monitoring the scan tool for DTCs.
  NOTE:
  After adjusting the mirror in one direction wait at least two seconds before adjusting the mirror in the opposite direction, as this will allow time for an active fault to set if present.
  
  Does the scan tool display: B164A-11-DRIVER MIRROR SIGNAL LAMP CONTROL - CIRCUIT SHORT TO GROUND?
  
  Yes
  - Go To 2.
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time. For vehicle's equipped with folding outside rearview mirrors, repeat the above test with the mirror folded. If this DTC is now active, Go To 2. For others, using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
