## EPS Indicator Circuit Troubleshooting

1. | Turn the ignition switch ON (II), start the engine and watch the EPS indicator. Does the EPS indicator come on? YES - If the EPS indicator comes on and goes off, it's OK. If the EPS indicator stays on blinks, alway check for an open or a short to ground in the SCS circuit. NO - Go to 2.

2. | Turn the ignition switch OFF, then ON (II) again and watch the brake system indicator. Does the brake system indicator come on? YES - Go to 3. NO - Repair open in the indicator power source circuit:n Blown No. 3 METER (7.5 A) fuse. Open in the wire between the No. 3 METER (7.5 A) fuse and gauge assembly. Open circuit inside the under-dash fuse/relay box.

3. | Turn the ignition switch OFF.

4. | Disconnect the gauge assembly 20P connector.

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

6. | Measure the voltage between the gauge assembly 22P connector terminal No. 2 and body ground. Is there battery voltage? YES - Go to 7. NO - Repair open in the wire between the gauge assembly and No. 3 METER (7.5 A) fuse.n

7. | Turn the ignition switch OFF.

8. | Check the EPS indicator bulb in the gauge assembly. Is the bulb OK? YES - Go to 9. NO - Repair the EPS indicatoer bulb.n

9. | Connect the gauge assembly 20P connector on the gauge assembly.

10. | Turn the ignition switch ON (II).

11. | Connect the gauge assembly 30P connector terminal No. 26 to body ground with a jumper wire. Does EPS indicator come on? YES - Go to 12. NO - Replace the bulb circuit board in the gauge assembly.n

12. | Turn the ignition switch OFF.

13. | Disconnect the negative cable from the battery.

14. | Disconnect the EPS control unit connector B (14P).

15. | Reconnect the negative cable to the battery.

16. | Turn the ignition switch ON (II).

17. | Connect the EPS control unit connector B (14P) terminal No. 13 to body ground with a jumper wire. Does EPS indicator come on? YES - Go to 18. NO - Repair open in the wire between the gauge assembly and EPS control unit.n

18. | Turn the ignition switch OFF.

19. | Disconnect the negative cable from the battery.

20. | Disconnect the EPS control unit connector A (4P).

21. | Check for continuity between body ground and the EPS control unit connector A (4P) terminal No. 4 to body ground. Is there continuty? YES - Go to 22. NO - Repair open in the wire between the EPS control unit and body ground (G451).n

22. | Reconnect the negative cable to the battery.

23. | Turn the ignition switch ON (II).

24. | Measure the voltage between the EPS control unit connector B (14P) terminal No. 6 and body ground. Is there battery voltage? YES - Go to 25. NO - Repair open in the wire between the EPS control unit connector B (14P) and No. 3 METER (7.5 A) fuse.n

25. | Turn the ignition switch OFF.

26. | Start the engine. Does EPS indicator go off? YES - Go to 27. NO - Repair short to body ground in the wire between the EPS indicator and EPS control unit.n

27. | Inspect the bulb circuit board in the gauge assembly. Is there normal? YES - Check for loose EPS control unit connectors. If necessary, substitute a known-good EPS control unit and recheck.n NO - Replace the bulb circuit board in the gauge assembly.n
