Diagnostic Test

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

Possible Causes
(A214) FUSED B (+) CIRCUIT OPEN OR SHORTED
(Z909) GROUND CIRCUIT OPEN
(D264) AND (D265) CAN INTERIOR (IHS) BUS (125K) CIRCUITS OPEN
PASSENGER DOOR MODULE

TEST FOR INTERMITTENT CONDITION
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. Using the scan tool, select ECU View.
  NOTE:
  A red "X" will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.
  
  Does the scan tool display a red "X" next to the module?
  
  Yes
  - Go To 2.
  No
  - The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched and partially broken wires and the wiring harness connectors for broken, bent, pushed out and corroded terminals.
(A214) FUSED B(+) CIRCUIT OPEN OR SHORTED

1. Turn the ignition off.
2. Disconnect the Passenger Door Module C3 harness connector.
3. Using a 12-volt test light connected to ground, check the (A214) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 3.
  No
  - Repair the (A214) Fused B(+) circuit for an open or short.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
(Z909) GROUND CIRCUIT OPEN

1. Using a 12-volt test light connected to 12-volts, check the (Z909) ground circuit.
  Does the test light illuminate brightly for each circuit?
  
  Yes
  - Go To 4.
  No
  - Repair the (Z909) ground circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
(D265) OR (D264) CAN IHS BUS (125K) CIRCUIT OPEN

1. Measure the resistance of the (D264) CAN IHS Bus (-) (125K) circuit between the TIPM C7 harness connector and the Passenger Door Module C3 harness connector.
2. Measure the resistance of the (D265) CAN IHS Bus (+) (125K) circuit between the TIPM C7 harness connector and the Passenger Door Module C3 harness connector.
  Is resistance below 5.0 Ohms on both circuits?
  
  Yes
  - Replace the Passenger Door Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Repair the (D265) or (D264) CAN IHS Bus (125K) circuit for an open. Inspect the connector for damage.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
