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

   -4. Turn the vehicle to the ON mode.

   -5. Select the EVAP TEST (ELCM) in the INSPECTION MENU, then select EVAP Leak Check Module Test with the HDS.

   EVAP TEST (ELCM)

   Is the result OK?

   YES 

   If the test result is PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the EVAP leak check module 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 .

   NO 

   The failure is duplicated. Go to step 2.

2. Open wire check (GND line)

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

   -2. Disconnect the following connector.

   EVAP leak check module 8P connector

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

   Test condition	Vehicle OFF (LOCK) mode
   	EVAP leak check module 8P connector: disconnected
   Test point 1	EVAP leak check module 8P connector (female terminals) No. 4:
   Test point 2	Body ground

   YES 

   Go to step 3.

   NO 

   Repair an open in the GND wire between the EVAP leak check module and body ground (G504).

3. Open wire check (ELCMP line)

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

   -2. Disconnect the following connector.

   PCM connector E (80P)

   -3. Connect terminals A and B with a jumper wire.

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

   Test condition	Vehicle OFF (LOCK) mode
   	PCM connector E (80P): disconnected
   	EVAP leak check module 8P connector: disconnected
   	EVAP leak check module 8P connector No. 3: jumped to body ground
   Test point 2	PCM connector E (80P) No. 47
   Test point 1	Body ground

   Is there continuity?

   YES 

   Replace the EVAP leak check module .

   NO 

   Repair an open in the ELCMP wire between the PCM (E47) and the EVAP leak check module.
