Diagnostic Test

ACTIVE DTC
1. Ignition on, engine not running.
2. With a scan tool, read DTCs.
  Is the DTC active at this time?
  
  Yes
  - Go To step 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
(T40) STARTER FEED CIRCUIT SHORTED TO GROUND
1. Turn the ignition.
2. Disconnect the Starter Relay.
3. Disconnect the C10 TIPM harness connector.
4. Measure the resistance between ground and the (T40) Starter Relay Output circuit in the C10 TIPM harness connector.
  Is the resistance below 100 ohms?
  
  Yes
  - Repair the short to ground in the (T40) Starter Relay Output circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Go to step 3
(T750) STARTER RELAY OUTPUT CIRCUIT SHORTED TO GROUND
1. Disconnect the Starter Solenoid connector.
2. Measure the resistance between ground and the (T750) Starter Relay Output circuit in the Starter Relay harness connector.
  Is the resistance below 100 ohms?
  
  Yes
  - Repair the short to ground in the (T750) Starter Relay Output circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Go to step 4
TIPM OPERATION
1. Reconnect the C10 TIPM harness connector.
2. Using a 12-volt test light connected ground, probe the (T40) Stater Relay Output circuit in the Starter Relay harness connector.
3. Crank the engine.
  Does the test light illuminate?
  
  Yes
  - Go to step 5
  No
  - Replace the Totally Integrated Power Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
STARTER RELAY
1. Turn the ignition off.
2. Install the Starter Relay.
  NOTE: The Stater Solenoid harness connector must still be disconnected at this time.
3. Crank the engine.
4. Using a 12-volt test light connected ground, probe the (T750) Stater Relay Output circuit in the Starter Solenoid harness connector.
  Does the test light illuminate?
  
  Yes
  - Replace the Starter.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Replace the Starter Relay.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
