Diagnostic Test
- CHECK FOR AN ACTIVE DTC
- Turn the ignition on.
- Using a scan tool, record and erase the Diagnostic Trouble Codes (DTCs).
- Turn the driver side turn signal on.
- Turn the approach lamps on, if equipped.
- Turn the rear defogger on, if equipped with heated mirror.
- Press and release the Mirror Select switch to select the Driver Outside Rearview Mirror.
- Operate the Mirror Adjust Switch in all directions several times while monitoring the scan tool for DTCs in the DDM.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 DTC to set, if present.
Is the DTC active?
Yes
- Go To 2
No
- The condition or conditions that originally set this DTC are not present at this time.
