How to Use A Programmed Smart Cable

NOTE:
^ If the PCM broadcast code stored in the Smart Cable is different than the code needed by the PCM, go to How to Reprogram a Smart Cable.

^ If the red light (# 3) on the Smart Cable comes on or flashes at any time during the procedure, the update was not completed. Go to How to Diagnose a Faulty Smart Cable.

* 1. Use the PGM Tester with the 5N201 or later software to check for and clear any existing ABS DTCs.

^ For 1996-97 SLX, go to step 4.

^ For 1998-99 SLX, go to step 1. *

2. Turn the ignition switch to LOCK (0).

3. Open the hood, and locate the Electronic Hydraulic Control Unit (EHCU) directly behind the passenger-side headlight assembly.





4. Disconnect the EHCU connector from the EHCU by pulling out the locking slide, then pulling the base of the connector straight up.

5. Turn the ignition switch to ON (II).





6. Connect the Smart Cable's large blue connector to the vehicle DLC (data link connector). Connect the other end of the Smart Cable to the DLC port on the Smart Cable Box. The green light (# 1) on the Smart Cable flashes, then glows steadily.

NOTE:
If the yellow (# 2) and green lights flash and then glow steadily, the PCM broadcast code already matches the code in the Smart Cable. Go to step 9.

7. Momentarily push and release the START button on the Smart Cable to begin the PCM Update. While the PCM is updating for 1 to 3 minutes, the yellow light on the Smart Cable flashes, and the green light glows steadily.

To avoid permanent PCM damage, do not disconnect the Smart Cable or turn the ignition switch to ACC (I) or Lock (0) while the yellow light is flashing.

8. When the yellow and green lights glow steadily, indicating that the update is complete, disconnect the Smart Cable from the DLC.

9. Turn the ignition switch to Lock (0).

* 10. Reconnect the EHCU connector to the EHCU if needed. *

11. Use the PGM Tester to clear any remaining DTCs

12. Recheck the broadcast code with the PGM Tester. The code must match the update you just installed.

13. If the vehicle still has the problem you tried to correct with the update, refer to the appropriate service manual or ETM for troubleshooting information.
