1. TEST FOR INTERMITTENT CONDITION Turn the ignition on. Using a scan tool, record and erase Diagnostic Trouble Codes (DTCs). Turn the turn signal on. Turn the puddle lamps on, if equipped with puddle lamp mirror. Turn the rear defogger on, if equipped with heated mirror. Press and release the Mirror Select switch to select the Passenger Outside Rearview Mirror. 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. Is the DTC active? Yes Go To 2 . No The conditions that caused this code to set are not present at this time. For vehicle's equipped with folding outside rearview mirrors, repeat test with mirror folded. If DTC is now active, Refer to 2 . Otherwise, use the wiring diagram/schematic as a guide and inspect the wiring and connectors. Perform the BODY VERIFICATION TEST.
