Diagnostic Test

WARNING: This page is about a different car, the 2012 RAM Pickup and 2012 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FOR AN ACTIVE DTC
NOTE:
Before proceeding with this diagnostic procedure, verify the Clockspring harness connectors are properly seated and verify proper pin terminal tension. A loose connection at any of these connectors may cause this DTC to set.
1. Turn the ignition on.
2. With the scan tool, read DTCs.
  Does the scan tool display this DTC as active?
  
  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.

1. Turn the ignition off.
2. Disconnect the Right Steering Wheel Switch harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (A909) Fused B (+) circuit.
  Is the voltage above 10.0 volts?
  
  Yes
  - Go To 3.
  No
  - Using the Wiring Information as a guide, repair the (A909) Fused B (+) circuit for an open. Inspect the related fuse. If the fuse is open, check the circuit for a short to ground.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
(Z911) GROUND CIRCUIT FOR AN OPEN
1. Turn the ignition off.
2. Measure the resistance between ground and the (Z911) Ground circuit at the Right Steering Wheel Switch harness connector.
  Is the resistance below 10K Ohms?
  
  Yes
  - Go To 4.
  No
  - Using the Wiring Information as a guide, repair the (Z911) Ground circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
RIGHT STEERING WHEEL SWITCH
1. Turn the ignition on.
2. Measure the voltage of the (D506) LIN BUS circuit at the Right Steering Wheel Switch harness connector.
  Is the voltage above 5 volts?
  
  Yes
  - Replace the Right Steering Wheel Switch in accordance with the Service Information. Refer to SWITCH, SPEED CONTROL, REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 5.
(D506) LIN BUS CIRCUIT FOR AN OPEN BETWEEN THE CLOCKSPRING AND RIGHT STEERING WHEEL SWITCH
1. Turn the ignition off.
2. Disconnect the Clockspring C8 harness connector.
3. Measure the resistance of the (D506) LIN BUS circuit between the Clockspring C8 and Right Steering Wheel Switch harness connectors.
  Is the resistance below 10K Ohms?
  
  Yes
  - Go To 6.
  No
  - Repair the (D506) LIN BUS circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CLOCKSPRING
1. Disconnect the Clockspring C2 harness connector.
2. Turn the ignition on.
3. Measure the voltage of the (D506) LIN BUS circuit at the Clockspring C2 harness connector.
  Is the voltage above 5 volts?
  
  Yes
  - Replace the Clockspring in accordance with the Service Information. Refer to CLOCKSPRING, REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 7.
(D506) LIN BUS CIRCUIT FOR AN OPEN BETWEEN THE CLUSTER AND THE CLOCKSPRING
1. Turn the ignition off.
2. Disconnect the Cluster C3 harness connector.
3. Measure the resistance of the (D506) LIN BUS circuit between the Clockspring C2 and Cluster C3 harness connectors.
  Is the resistance below 10K Ohms?
  
  Yes
  - Replace the Cluster in accordance with the Service Information. Refer to REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Repair the (D506) LIN BUS circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
