Diagnostic Test

WARNING: This page is about a different car, the 2015 RAM 3500 HD and 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. Using a scan tool, record and erase the Diagnostic Trouble Codes (DTCs).
    3. Turn the driver side turn signal on.
    4. Turn the approach lamps on, if equipped.
    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 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. 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 and repair as necessary. If no problems are found, test complete.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

    3. Turn the ignition on.
    4. Measure the voltage between ground and the (A856) 5-volt Supply circuit at the Driver Door Module (Module Side) connector.

      Is the Voltage above 4.5 Volts?

      Yes 

      • Go To  3

      No 

  3. CHECK THE (A856) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO GROUND 
    1. Turn the ignition off.
    2. Check for continuity between ground and the (A856) 5-Volt Supply circuit at the Driver Outside Rearview Mirror C1 connector.

      Is there continuity between ground and the (A856) 5-Volt Supply circuit?

      Yes 

      • Repair the (A856) 5-Volt Supply circuit for a short to ground.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  4
  4. CHECK THE (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    1. Check for continuity between ground and the (P67) Driver Mirror Vertical Position Signal circuit at the Driver Outside Rearview Mirror C1 harness connector.

      Is there continuity between ground and the (P67) Driver Mirror Vertical Position Signal circuit?

      Yes 

      • Repair the (P67) Driver Mirror Vertical Position Signal circuit for a short to ground.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  5
  5. CHECK THE (P65) DRIVER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    1. Check for continuity between ground and the (P65) Driver Mirror Horizontal Position Signal circuit at the Driver Outside Rearview Mirror C1 harness connector.

      Is there continuity between ground and the (P65) Driver Mirror Horizontal Position Signal circuit?

      Yes 

      • Repair the (P65) Driver Mirror Horizontal Position Signal circuit for a short to ground.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  6
  6. CHECK (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR AN OPEN 
    1. Connect an ohmmeter between the (P67) Driver Mirror Vertical Position Signal circuit and the (P69) Driver Mirror Sensor ground circuit at the Driver Outside Rearview Mirror C1 (Component Side) harness connector.
    2. Manually move the mirror Up and Down while observing the ohmmeter.

      Does the resistance measure between approximately 1.2K Ohms and 2.4K Ohms as you move the mirror from Up to Down?

      Yes 

      • Go To  7

      No 

  7. CHECK (P65) DRIVER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR AN OPEN 
    1. Connect an ohmmeter between the (P65) Driver Mirror Horizontal Position Signal circuit and the (P69) Driver Mirror Sensor ground circuit at the Driver Outside Rearview Mirror C1 (Component Side) harness connector.
    2. Manually move the mirror Left to Right while observing the ohmmeter.
