Is there continuity? YES - Repair short to body ground in the appropriate sensor circut between the torque sensor and EPS control unit.n NO - Go to 9.

9. | Reconnect the negative cable to the battery.

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

11. | Measure the voltage between the appropriate EPS control unit connector B (14P) terminal and body ground (see table).
Terminal name | EPS control unit connector B terminal No.

13. | Check for continuity between the appropriate EPS control unit connector B (14P) terminal and body ground (see table). Is there continuty? YES - Go to 14. NO - Repair open in the appropriate torque sensor wire circuit between the EPS control unit and the torque sensor.n

14. | Turn the ignition switch OFF.

15. | Disconnect the negative cable from the battery.

16. | Substitute a know-good EPS control unit, and connect the all disconnected connectors.

17. | Reconnect the negative cable to the battery.

18. | Start the engine. Does the EPS indicator come on? YES - Go to 19. NO - Check for loose EPS control unit connectors. If necessary, substitute a known-good EPS control unit and retest.n

19. | Stop the engine, and verify the DTC. Is DTC11, DTC15 or DTC16 indicated? YES - Check for loose torque sensor connectors. If necessary, substitute a known-good steering gearbox and recheck.n NO - Perform the appropriate troubleshooting for the code indicated.n
