Diagnostic Test

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN ACTIVE DTC 
    NOTE:

    Make sure the battery is fully charged.

    1. Turn the ignition on.
    2. With the scan tool, create a Vehicle Scan Report and attach it to the repair order.
    3. With the scan tool, select: "RFH" and "System Tests".
    4. Perform the Door Handle Verification Test. This will activate the Module to retest for DTCs.
    5. With the scan tool, read the Active DTCs and wait one (1) minute.

      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.
  2. TEST HANDLE FUNCTIONS 
    1. Lower the driver door window.
    2. Turn the ignition off.
    3. Have the FOBIK outside and within 10 cm. to 1.5 m. (4 in. to 5 ft.) of the driver door handle.
      NOTE:

      In the next steps, wait two (2) seconds between each Lock and Unlock activation as there is a two second delay after each Lock action.

    4. With the scan tool, select "RFH", "Data" and scroll to "Passive Entry Function Carried Out".
    5. Press the Lock button and observe "Passive lock at left front door".
    6. Grab the door handle and observe "Passive entry at left front door".
    7. Repeat steps 5 and 6 two more times.

      Is the Module receiving the inputs on the screen as you do them?

      Yes
