Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.

Possible Causes
(A107) (A111) FUSED B(+) CIRCUIT OPEN OR SHORTED
(Z905) GROUND CIRCUIT OPEN
(F941) IGNITION RUN/START CONTROL OUTPUT CIRCUIT OPEN OR SHORTED
(D52) CAN C BUS (+) CIRCUIT OPEN
(D51) CAN C BUS (-) CIRCUIT OPEN
ANTILOCK BRAKE MODULE (ABS)

TEST FOR INTERMITTENT CONDITION
NOTE:
Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.
1. Turn the ignition on.
  NOTE:
  Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. With the scan tool, read the module status.
  NOTE:
  Check the TIPM for any active CAN C hardware DTCs, perform DTC before proceeding.
  
  Does the scan tool indicate that the module is active on the bus?
  
  Yes
  - The no response condition is 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.
  No
  - Go To 2.
