DTC P0615 (1.5 L Engine)

DTC P0615  : Starter Cut Relay Diagnosis Circuit Malfunction

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 A (8P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	Relay circuit board connector A (8P): disconnected
   	PCM connector A (50P): disconnected
   Test point 1	Relay circuit board connector A (8P) (female terminals) No. 8:
   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. D20 (10 A)
   Location	Under-dash fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 6.

   NO 

   Check for a short in the IG1 STARTER CUT wire between the No. D20 (10 A) fuse and the relay circuit board. If the wire is OK, replace the under-dash fuse/relay box . Also replace the No. D20 (10 A) fuse.

6. Open wire check (IG1 STARTER CUT line)

   -1. Disconnect the following connectors.

   Under-dash fuse/relay box connector C (27P)

   Relay circuit board connector B (6P)

   -2. Connect terminals A and B with a jumper wire.

   Terminal A	Under-dash fuse/relay box connector C (27P) (female terminals) No. 23:
   Terminal B	Body ground

   -3. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Relay circuit board connector B (6P): disconnected
   	Under-dash fuse/relay box connector C (27P): disconnected
   	Under-dash fuse/relay box connector C (27P) No. 23: jumped to body ground
   Test point 1	Relay circuit board connector B (6P) (female terminals) No. 4:
   Test point 2	Body ground

   Courtesy of HONDA, U.S.A., INC.

   Is there continuity?

   YES 

   Go to step 7.

   NO 

   Repair an open in the IG1 STARTER CUT wire between the relay circuit board and the under-dash fuse/relay box.

7. Relay circuit board check

   -1. Remove and test the relay circuit board .

   Is the relay circuit board OK?

   YES 

   Replace the under-dash fuse/relay box .

   NO 

   Replace the relay circuit board .
