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
(A209) FUSED B(+) CIRCUITS OPEN OR SHORTED
(Z908) GROUND CIRCUITS OPEN
(F202) IGNITION RUN/START CONTROL OUTPUT CIRCUIT OPEN OR SHORTED
(F1) IGNITION OFF/RUN/START CONTROL OUTPUT CIRCUIT OPEN OR SHORTED
(F342) FUSED ASD RELAY OUTPUT CIRCUIT OPEN OR SHORTED
(D65) CAN C BUS(+) CIRCUIT OPEN
(D64) CAN C BUS(-) CIRCUIT OPEN
POWERTRAIN CONTROL MODULE (PCM)

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. 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.
  
  NOTE:
  Check the TIPM for any active CAN C hardware DTCs, perform DTC before proceeding.
  
  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.
(A209) FUSED B(+) CIRCUITS OPEN OR SHORTED

1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
  CAUTION:
  Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the PCM Pinout Box (special tool #8815A, Kit, NGC, 38 Position) to perform diagnosis.
3. Using a 12-volt test light connected to ground, check the (A209) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 3.
  No
  - Repair the open or short to ground in the (A209) Fused B(+) circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(Z908) GROUND CIRCUITS OPEN

1. Disconnect the PCM C4 harness connector.
2. Using a 12-volt test light connected to 12-volts, check each (Z908) Ground circuit for the PCM C1 and PCM C4 harness connectors.
  Does the test light illuminate brightly for each circuit?
  
  Yes
  - Go To 4.
  No
  - Repair the open in the (Z908) Ground circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(F202) IGNITION RUN/START CONTROL OUTPUT CIRCUIT OPEN OR SHORTED

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F202) Ignition Run/Start Control Output circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 5.
  No
  - Repair the open or short to ground in the (F202) Ignition Run/Start Control Output circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(F1) IGNITION OFF/RUN/START CONTROL OUTPUT CIRCUIT OPEN OR SHORTED

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F1) Ignition Off/Run/Start Control Output circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 6.
  No
  - Repair the open or short to ground in the (F1) Ignition Off/Run/Start Control Output circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(F342) FUSED ASD RELAY OUTPUT CIRCUIT OPEN OR SHORTED

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F342) Fused ASD Relay Output circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To 7.
  No
  - Repair the open or short to ground in the (F342) Fused ASD Relay Output circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
