Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN INTERMITTENT CONDITION 
    1. Turn the ignition on and open one of the front doors.
      NOTE:

      A front door must remain open whenever checking or erasing Amplifier DTCs.

    2. Using the scan tool, record and erase the Amplifier DTCs.
    3. Cycle the ignition switch from on to off, wait five seconds and then back to on.
    4. Turn the Radio on.
    5. Adjust the speakers to the front and center.
    6. Using the scan tool, read the active Amplifier DTCs.

      Does the scan tool display active: B1464-00-CHANNEL 1 AUDIO SPEAKER OUTPUT - CIRCUIT SHORTED TOGETHER?

      Yes 

      • Go To  2

      No 

      • Test complete, 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.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

      NOTE:

      The graphic shows the connector for reference only. Measure at the speaker terminals.

      Is the resistance of the speaker less than 1 Ohm?

      Yes

      Is the resistance below 10K Ohms?

      Yes 

      • Repair the (X209) Left I/P Speaker (+) circuit for a short to the (X299) Left I/P Speaker (-) circuit.
