NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Try to start the engine.

   -4. Check for Pending or Confirmed DTCs with the HDS.

   P0615 Starter Cut Relay Diagnosis Circuit Malfunction

   Is DTC P0615 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the relay circuit board, and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

2. DTC check

   -1. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC
   P16F3 Starter Cut Relay 1 Control Circuit Low Voltage
   P16F4 Starter Cut Relay 2 Control Circuit Low Voltage

   Are DTC P16F3 and P16F4 indicated?

   YES 

   Go to the troubleshooting for DTC P16F3 and P16F4 .

   NO 

   Go to step 3.

3. Determine possible failure area (START DIAG line, others)

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Try to start the engine.

   Does the engine start?

   YES 

   Go to step 4.

   NO 

   Go to step 5.

4. Open wire check (START DIAG line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Jump the SCS line with the HDS, and wait more than 1 minute.

   -3. Disconnect the following connectors.

   PCM connector A (50P)

   Relay circuit board connector C (22P)

   -4. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Relay circuit board connector C (22P): disconnected
   	PCM connector A (50P): disconnected
   Test point 1	Relay circuit board connector C (22P) (female terminals) No. 14:
   Test point 2	PCM connector A (50P) No. 19

   Is there continuity?

   YES 

   The START DIAG wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

   NO 

   Repair an open in the START DIAG wire between the PCM (A19) and the relay circuit board.

5. Fuse check

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Check the following fuse.

   Fuse

   No. A43

   Is the fuse OK?

   YES 

   Go to step 6.

   NO 

   Check for a short in the IG1 STARTER CUT wire between the No. A43 fuse and the relay circuit board. Also replace the No. A43 fuse.

6. Open wire check (IG1 STARTER CUT line)

   -1. Disconnect the following connector.

   Relay circuit board connector C (22P)

   -2. Turn the vehicle to the ON mode.

   -3. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode
   	Relay circuit board connector C (22P): disconnected
   Test point 1	Relay circuit board connector C (22P) (female terminals) No. 20:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The IG1 STARTER CUT wire is OK. Replace the relay circuit board .

   NO 

   Repair an open in the IG1 STARTER CUT wire between the relay circuit board and the No. A43 fuse .
