Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, read DTCs.

      Is the DTC active?

      No 

      • The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chaffed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
  2. BRAKE WEAR SENSOR
