Pinpoint Test C: DTC P0615:12 Or P0617:12

Starting System

Pinpoint Test C: DTC P0615:12 or P0617:12

Refer to Wiring Diagram Set 20, Starting System for schematic and connector information Electrical Diagrams.

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Normal Operation - (Without Intelligent Access)

When the ignition is turned to the START position, the PCM receives a request to start the engine and supplies voltage to the starter relay coil. The PCM monitors the start request circuit for faults. If voltage is detected on the start request circuit and the starter relay is not in an active state, the PCM sets a DTC.

- DTC P0617:12 (Starter Relay Circuit High: Circuit Short to Battery)- sets when the PCM detects excessive current on the starter relay circuit and the output is not activated.

Normal Operation - With Intelligent Access (IA)

When the start/stop switch is pressed and released along with either the brake pedal (vehicles equipped with automatic transmission) or Clutch Pedal Position (CPP) switch (vehicles equipped with manual transmission) input, the Remote Function Actuator (RFA) module receives a request from the Intelligent Access (IA) key to start the engine. The RFA (Remote Function Actuator) module then supplies voltage to the starter relay coil. The RFA (Remote Function Actuator) module monitors the start request circuit for faults. If voltage is detected on the start request circuit and the starter relay is not in an active state, the RFA (Remote Function Actuator) module sets a DTC.

- DTC P0615:12 (Starter Relay Circuit High: Circuit Short to Battery)- sets when the RFA module detects current output above threshold on the starter relay circuit and the output is not activated.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- RFA (Remote Function Actuator) module

- PCM

- Starter relay

PINPOINT TEST C : DTCs P0615:12 OR P0617:12

C1 CHECK THE STARTER REQUEST CIRCUIT FOR A SHORT TO VOLTAGE

- Ignition OFF.

- Disconnect: Starter Relay.

- Disconnect: RFA (Remote Function Actuator) module C3503C (vehicles equipped with IA (Intelligent Access)) or PCM C175B (vehicles without IA (Intelligent Access)).

- Disconnect: ACM (Audio Control Module) C240A.

- Ignition ON.

- Measure the voltage between BJB (Battery Junction Box) starter relay cavity 1, circuit CDC54 (WH/GN), harness side and ground.





Is any voltage present?

Yes
REPAIR circuit CDC54 (WH/GN). TEST the system for normal operation.

No
GO to C2.

C2 CHECK THE STARTER MOTOR RELAY

- Swap the starter relay with a known good relay.

- Enter the following diagnostic mode on the scan tool: Self Test- RFA (Remote Function Actuator) module (vehicles equipped with IA (Intelligent Access)) or PCM (vehicles without IA (Intelligent Access)).

Was RFA (Remote Function Actuator) DTC P0615:12 or PCM DTC P0617:12 retrieved on-demand during self-test?

Yes

For vehicles without IA (Intelligent Access), GO to C3.

For vehicles with IA (Intelligent Access), GO to C4.

No
INSTALL a new starter relay. TEST the system for normal operation.

C3 CHECK FOR CORRECT PCM OPERATION

- Ignition OFF.

- Disconnect all PCM connectors.

- Check the connectors for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all PCM connectors and make sure they seat correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new PCM. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

C4 CHECK FOR CORRECT RFA (Remote Function Actuator) MODULE OPERATION

- Ignition OFF.

- Disconnect all RFA (Remote Function Actuator) module connectors.

- Check the connectors for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all RFA (Remote Function Actuator) module connectors and make sure they seat correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new RFA (Remote Function Actuator) module. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
