Diagnostic Test

WARNING: This page is about a different car, the 2012 RAM Pickup and 2012 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. TEST FOR INTERMITTENT CONDITION 
    1. Turn the ignition on.
    2. Using a scan tool, record and erase Diagnostic Trouble Codes (DTC's).
    3. Turn the turn signal on, if equipped with turn signal mirror.
    4. Turn the puddle lamps on, if equipped with puddle lamp mirror.
    5. Turn the rear defogger on.
    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 DTC's.
      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, go to  2. Otherwise, use the wiring diagram/schematic as a guide and inspect the wiring and connectors.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  2. CHECK (C16) DRIVER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO GROUND
