38. Reconnect PCM connector A (73P).
39. Reconnect the EGR valve 6P connector.
40. Turn the ignition switch ON (II).
41. Reset the PCM with the HDS.
42. Do the PCM idle learn procedure.
43. Start the engine. Hold the engine speed at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, then let it idle.
44. Do the EGR TEST in the INSPECTION MENU with the HDS.
Is EGR system OK?
YES - Go to step 51.
NO - Go to step 45.
45. Turn the ignition switch OFF.
46. Replace the EGR valve.
47. Turn the ignition switch ON (II).
48. Reset the PCM with the HDS.
49. Do the PCM idle learn procedure.
50. Start the engine. Hold the engine speed at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, then let it idle.
51. Test-drive the vehicle under load for about 10 minutes. Try to keep the engine speed in the 1,700 - 2,500 rpm range.
52. Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P2413 is indicated, check for poor connections or loose terminals at the EGR valve and PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
