24. Jump the SCS line with the HDS.
25. Disconnect PCM connector C (49P).
26. Disconnect the EGR valve 5P connector.
27. At the EGR valve side, measure the resistance between EGR valve 5P connector terminals No. 2 and No. 3.
Is there 100 kOhms or more?
YES -
Go to step 46.
NO -
Go to step 28.
28. At the EGR valve side, measure the resistance between EGR valve 5P connector terminals No. 2 and No. 4.

NO -
Go to step 29.
29. Check for continuity between PCM connector terminal C10 and body ground.
Is there continuity?
YES -
Repair a short in the wire between the PCM(C10) and the EGR valve, then go to step 45.
NO -
Go to step 30.
30. Connect EGR valve 5P connector terminal No. 1 to body ground with a jumper wire.
31. Check for continuity between PCM connector terminal C10 and body ground.
Is there continuity?
YES -
Go to step 32.
NO -
Repair an open in the wire between the PCM (C10) and the EGR valve, then go to step 47.
32. Check for continuity between EGR valve 5P connector terminal No. 5 and body ground.
Is there continuity?
YES -
Go to step 33.
NO -
Repair an open in the wire between the EGR valve and G101, then go to step 47.
33. Reconnect PCM connectors C (49P).
34. At the EGR valve side, connect the battery positive terminal to EGR valve 5P connector terminal No. 1 with a jumper wire.
35. 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?
YES -
Go to step 53.
NO -
Go to step 36.
36. Turn the ignition switch to LOCK (0).
37. Remove the EGR valve Service and Repair.
38. Clean any carbon build-up on the EGR valve with throttle plate cleaner.
39. Reinstall the EGR valve Service and Repair.
40. Reconnect all connectors.
41. Turn the ignition switch to ON (II).
42. Reset the PCM with the HDS.
43. Do the PCM idle learn procedure PCM Idle Learn Procedure.
44. Do the EGR TEST in the INSPECTION MENU with the HDS.
Is the result OK?
YES -
Go to step 52.
NO -
Go to step 45.
