DTC P24BE

DTC P24BE  : Canister Change Over Valve Control Circuit Low Voltage

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 in the Function Test Menu, then select EVAP Leak Check Module Test with the HDS.

   EVAP TEST

   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. Fuse check

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

   -2. Check the No. B11 fuse .

   Is the fuse OK?

   YES 

   Go to step 3.

   NO 

   Replace the No. B11 fuse. Also check for a short in the No. B11 fuse circuit if needed.

3. Open wire check (DBW RLY OUT line)

   -1. Disconnect the following connector.

   EVAP leak check module 8P connector

   -2. Turn the vehicle to the ON mode.

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

   Test condition	Vehicle ON mode
   	EVAP leak check module 8P connector: disconnected
   Test point 1	EVAP leak check module 8P connector (female terminals) No. 5:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The DBW RLY OUT wire is OK. Go to step 4.

   NO 

   Repair an open in the DBW RLY OUT wire between the under-hood fuse/relay box and the EVAP leak check module.

4. Shorted wire check (VSV 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 connector.

   PCM connector A (50P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	EVAP leak check module 8P connector: disconnected
   	PCM connector A (50P): disconnected
   Test point 1	PCM connector A (50P) No. 6
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the VSV wire between the PCM (A6) and the EVAP leak check module.

   NO 

   The VSV wire is not shorted. Go to step 5.

5. Open wire check (VSV line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	EVAP leak check module 8P connector: disconnected
   	PCM connector A (50P): disconnected
   Test point 1	PCM connector A (50P) No. 6
   Test point 2	EVAP leak check module 8P connector (female terminals) No. 1:

   Is there continuity?

   YES 

   The VSV wire is OK. Go to step 6.

   NO 

   Repair an open in the VSV wire between the PCM (A6) and the EVAP leak check module.

6. EVAP leak check module check

   -1. Substitute a known-good EVAP leak check module .

   -2. Reconnect all connectors.

   -3. Exit the SCS mode with the HDS.

   -4. Turn the vehicle to the ON mode.

   -5. Reset the PCM with the HDS .

   Reset PCM

   -6. Select the EVAP TEST in the Function Test Menu, then select EVAP Leak Check Module Test with the HDS.

   EVAP TEST

   Is the result OK?

   YES 

   If the test result is PASSED, replace the original EVAP leak check module . 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. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
