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
(A106) FUSED B(+) CIRCUIT OPEN OR SHORTED
(Z911) GROUND CIRCUIT OPEN
(D51) CAN C BUS (-) CIRCUIT OPEN
(D52) CAN C BUS (+) CIRCUIT OPEN
WIRELESS IGNITION NODE (WIN)

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 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.
CHECK THE (A106) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT

1. Turn the ignition off.
2. Disconnect the Wireless Ignition Node harness connector.
3. Using a 12-volt test light connected to ground, check the (A106) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 3.
  No
  - Repair the open or short in the (A106) Fused B(+) circuit.
  - Perform the WIN VERIFICATION TEST. Refer to Standard Procedure .
CHECK THE (Z911) GROUND CIRCUIT FOR AN OPEN

1. Using a 12-volt test light connected to 12-volts, check the (Z911) Ground circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 4.
  No
  - Repair the open in the (Z911) Ground circuit.
  - Perform the WIN VERIFICATION TEST. Refer to Standard Procedure .
CHECK THE (D52) CAN C BUS (+) CIRCUIT FOR AN OPEN

1. Disconnect the TIPM C7 harness connector.
2. Measure the resistance of the (D52) CAN C Bus (+) circuit between the TIPM C7 harness connector and the Wireless Ignition Node harness connector.
  Is resistance below 5.0 Ohms?
  
  Yes
  - Go To 5.
  No
  - Repair the open in the (D52) CAN C Bus (+) circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

1. Measure the resistance of the (D51) CAN C Bus (-) circuit between the TIPM C7 harness connector and the Wireless Ignition Node harness connector.
  Is resistance below 5.0 Ohms?
  
  Yes
  - Replace the Wireless Ignition Node in accordance with the Service Information. Refer to RECEIVER, Wireless Ignition Node , Removal .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Repair the open in the (D51) CAN C Bus (-) circuit.
