Diagnostic Test

WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

DTC IS ACTIVE
NOTE:
If there are any other DTCs present (in ANY OTHER portion of the Engine/PCM system), perform the Diagnostics for those DTCs before continuing with this one.
1. Ignition on, engine not running.
2. With the scan tool, erase DTCs in the Powertrain Control Module (PCM).
3. Start the engine and allow it to reach normal operating temperature.
4. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .
ASD RELAY
1. Turn the ignition off.
2. Install a known good relay in place of the ASD Relay.
3. Turn the ignition on.
4. With the scan tool, erase DTCs.
5. Perform several ignition key cycles, pausing for at least 40 seconds between each cycle.
6. Turn the ignition on.
7. With the scan tool, read ECM DTCs.
  Did this DTC set again?
  
  Yes
  - Go To 3
  No
  - Repair is complete.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
(K51) ASD RELAY CONTROL CIRCUIT SHORT TO GROUND
1. Turn the ignition off.
2. Remove the ASD Relay from the PDC.
3. Disconnect the PCM C1 harness connector.
4. Measure the resistance between ground and the (K51) ASD Relay Control circuit at the PCM C1 harness connector while wiggling the wiring harness and connectors.
  Does the resistance remain above 10k Ohms while wiggling the wiring harness and connectors?
  
  Yes
  - Go To 5
  No
  - Go To 4
POWER DISTRIBUTION CENTER
1. Disconnect the PDC C3 harness connector.
2. Measure the resistance between ground and the (K51) ASD Relay Control circuit at the PCM C1 harness connector while wiggling the wiring harness and connectors.
  Does the resistance remain above 10k Ohms while wiggling the wiring harness and connectors?
  
  Yes
  - Replace the Power Distribution Center in accordance with the service information.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Repair the (K51) ASD Relay Control circuit for a short to ground.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
ASD RELAY OUTPUT CIRCUIT SHORTED TO VOLTAGE
1. Reconnect the PCM C1 harness connector.
2. Turn the ignition on.
3. Measure the voltage on the ASD Relay Output circuit at the ASD Relay Output terminal.
  Is the voltage above 1.0 Volts?
  
  Yes
  - Go To 6
  No
  - Go To 7
POWER DISTRIBUTION CENTER
1. Turn the ignition off.
2. Disconnect the PDC C3 harness connector.
3. Turn the ignition on.
4. Measure the voltage on the ASD Relay Output circuit at the ASD Relay Output terminal.
  Is the voltage above 1.0 Volts?
  
  Yes
  - Replace the Power Distribution Center in accordance with the service information.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Refer to the Fuses/Relay-ASD System Wiring Diagram Information. Determine which of the 3 ASD Relay Output circuits (F342, F343, or F344) is above 1.0 Volts (with the ASD Relay disconnected) and repair that circuit for a short to voltage.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
CHECK THE PCM POWER AND GROUND CIRCUITS
1. Turn the ignition off.
2. Reconnect the ASD Relay.
3. Refer to DIAGNOSIS AND TESTING and perform CHECKING THE PCM POWER AND GROUNDS and verify proper Ignition, Battery and Ground circuits at the PCM.
  Were any problem found with the PCM Ignition, Battery or Ground circuits?
  
  Yes
  - Repair or replace as necessary.
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Replace the Powertrain Control Module in accordance with the service information. Refer to REMOVAL .
  - Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
