  1. Check for continuity between ECM connector terminal B30 and body ground.
Is there continuity?
YES -
Repair short in the wire between the ECM (B30) and the EGR valve, then go to Step 44 .

Go to Step 20 .

  1. Check for continuity between ECM connector terminal B30 and EGR valve 5P connector terminal No. 2.
Is there continuity?
YES -
Go to Step 21 .
NO -
Repair open in the wire between the ECM (B30) and the EGR valve, then go to Step 44 .
  1. Turn the ignition switch to LOCK (0).
  1. If not already done, disconnect the EGR valve 5P connector.

  1. At the EGR valve side, measure the resistance between EGR valve 5P connector terminals No. 2 and No. 3.
Is there 100 kΩ or more?
YES -
Go to Step 43 .
NO -
Go to Step 24 .

  1. At the EGR valve side, measure the resistance between EGR valve 5P connector terminals No. 2 and No. 4.
Is there 100 kΩ or more?
YES -
Go to Step 43 .
NO -
Go to Step 25 .
  1. If not already done, jump the SCS line with the HDS.
  1. If not already done, disconnect ECM connector B (49P).

  1. Check for continuity between ECM connector terminal B2 and body ground.
Is there continuity?
YES -
Repair short in the wire between the ECM (B2) and the EGR valve, then go to Step 44 .
NO -
Go to Step 28 .

  1. Check for continuity between ECM connector terminal B2 and EGR valve 5P connector terminal No. 1.
Is there continuity?
YES -
Go to Step 29 .
NO -
Repair open in the wire between the ECM (B2) and the EGR valve, then go to Step 44 .

  1. Check for continuity between EGR valve 5P connector terminal No. 5 and body ground.
Is there continuity?
YES -
Go to Step 30 .
NO -
Repair open in the wire between the EGR valve and G101, then go to Step 44 .
  1. Reconnect ECM connector B (49P).

  1. At the EGR valve side, connect the battery positive terminal to EGR valve 5P connector terminal No. 1 with a jumper wire.
  1. Start the engine, and let it idle. Then connect the battery negative terminal to EGR valve 5P connector terminal No. 5 with a jumper wire.
Does the engine stall or run roughly?
YES -
Go to Step 51 .
NO -
Go to Step 33 .
  1. Turn the ignition switch to LOCK (0).
  1. Clean the intake manifold EGR port and the EGR pipe with throttle plate and induction cleaner. Also, clean the passage inside the EGR valve with throttle plate and induction cleaner.
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Reset the ECM with the HDS.
  1. Do the EGR TEST in the INSPECTION MENU with the HDS.
Is the result OK?
YES -
Go to Step 49 .
NO -
Go to Step 42 .
  1. Turn the ignition switch to LOCK (0).
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Reset the ECM with the HDS.
  1. Do the EGR TEST in the INSPECTION MENU with the HDS.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P2413 indicated?
YES -
Check for poor connections or loose terminals at the EGR valve and the ECM, then go to Step 1 .
NO -
Go to Step 50 .
  1. Monitor the OBD STATUS for DTC P2413 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES -
Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in Step 49 , go to the indicated DTC's troubleshooting.■
NO -
If the screen indicates FAILED, check for poor connections or loose terminals at the EGR valve and the ECM, then go to Step 1 . If the screen indicates EXECUTING, keep testing until a result comes on. If the screen indicates OUT OF CONDITION or NOT COMPLETED, go to Step 47 .
  1. Reconnect all connectors.
  1. Do the EGR TEST in the INSPECTION MENU with the HDS.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P2413 indicated?
YES -
Check for poor connections or loose terminals at the EGR valve and the ECM. If the ECM was updated, substitute a known-good ECM, then go to Step 52 . If the ECM was substituted, go to Step 1 .
NO -
Go to Step 55 .
  1. Monitor the OBD STATUS for DTC P2413 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES -
If the ECM was updated, troubleshooting is complete. If the ECM was substituted, replace the original ECM. If any other Temporary DTCs or DTCs were indicated in Step 54 , go to the indicated DTC's troubleshooting.■
NO -
If the screen indicates FAILED, check for poor connections or loose terminals at the EGR valve and the ECM. If the ECM was updated, substitute a known-good ECM, then go to Step 53 . If the ECM was substituted, go to Step 1 . If the screen indicates EXECUTING, keep testing until a result comes on. If the screen indicates OUT OF CONDITION or NOT COMPLETED, go to Step 53 .
