DIAGNOSIS
1. Verify that the HDS has software version 1.013.008 installed. Previous versions will not do this diagnosis.
2. Connect the HDS to the 16P data link connector (DLC).
3. Turn the ignition switch to ON (II). Turn on the HDS.
4. At the screen prompts, enter the VIN and the odometer reading, and then verify the correct date/ time.
5. Select the Mode Menu. Then select Honda Systems.
6. From the System Selection Menu screen, select PGM F1.
7. From the Mode Menu screen, select Snapshot.
8. From the Trigger Type menu, select the Fast Sampling button.
9. From the High Speed menu screen, select these parameters: Engine Speed, VSS, ECT Sensor, Map Sensor, IP Sensor, EGR-L-Command, and EGR LIFT. Then select the Green Check button.
10. When the Trigger Type menu is displayed, select Manual, select Record Time for 30 seconds, and move the trigger point to the middle. Then select the Blue Check button. Check that the defaulted trigger point is in the middle.
11. With the engine completely warmed up, have an assistant drive the vehicle while you operate the HDS. Drive the vehicle between 40 and 55 mph on a smooth road surface. Apply light throttle with the transmission in 5th gear (between 1,500 and 2,000 rpm). If hesitation is felt, select the Snapshot Manual Trigger button.
NOTE:
The snapshot must be done with two people so that one person can drive and the other can operate the HDS.
12. When the drive is complete, the Snapshot dialog box is displayed. Select Yes, then select OK. At this point, the snapshot is stored
13. Select the Folder button, then select the current Snapshot that was just created.
14. Select the Tool button. Under the line graph column, select EGR L COMMAND and EGR LIFT.
15. Select the Line Graph button.
^ If the EGR LIFT graph follows the EGR L COMMAND graph, the EGR valve is OK. Troubleshoot other causes for the symptom.
^ If the EGR LIFT graph is different from the EGR L COMMAND graph, the EGR valve is bad. Go to REPAIR PROCEDURE.
REPAIR PROCEDURE
1. Remove the intake manifold cover.
2. Disconnect the EGR valve connector.
