Is there continuity?

YES -Substitute a known-good throttle actuator control module (see THROTTLE ACTUATOR
CONTROL MODULE REPLACEMENT ), then go to step 19 and recheck. If DTC P2176 is not
indicated, replace the original throttle actuator control module (see THROTTLE ACTUATOR
CONTROL MODULE REPLACEMENT ), then go to step 19.

NO -Repair open in the wires between the throttle body and the throttle actuator control module (motor
drive lines), then go to step 19.

17. Turn the ignition switch OFF.

18. Replace the throttle body (see THROTTLE BODY REMOVAL/INSTALLATION ).

19. Reconnect all connectors.

20. Turn the ignition switch ON (II).

21. Reset the ECM/PCM with the HDS.

22. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

23. Turn the ignition switch OFF.

24. Turn the ignition switch ON (II), and wait 10 seconds.

25. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P2176 indicated?

YES -Check for poor connections or loose terminals at the throttle body and the throttle actuator control
module, clean the throttle body (see THROTTLE BODY CLEANING ), then go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

DTC P2552: THROTTLE ACTUATOR CONTROL MODULE RELAY MALFUNCTION

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Do the ETCS TEST in the INSPECTION MENU with the HDS.

Is the RELAY circuit OK ?

YES -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
the throttle actuator control module relay, the throttle actuator control module, and the ECM/PCM.

NO -Go to step 4.

4. Turn the ignition switch OFF.

5. Remove the throttle actuator control module relay (A).

6. Test the throttle actuator control module relay (see POWER RELAY TEST ).

Is the relay OK?

YES -Go to step 7.

NO -Replace the throttle actuator control module relay, then go to step 10.

7. Jump the SCS line with the HDS.

8. Disconnect ECM/PCM connector D (17P).

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot, and
review the general troubleshooting information (see GENERAL
TROUBLESHOOTING INFORMATION ).

Is there continuity?

YES -Repair short in the wire between the throttle actuator control module relay and the ECM/PCM
(D15), then go to step 10.

NO -Go to step 17.

10. Reconnect all connectors.

11. Turn the ignition switch ON (II).

12. Reset the ECM/PCM with the HDS.

13. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

14. Turn the ignition switch OFF.

15. Turn the ignition switch ON (II), and wait 10 seconds.

16. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P2552 indicated?

YES -Check for poor connections or loose terminals at the throttle actuator control module relay, the
throttle actuator control module, and the ECM/PCM, then go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

17. Reconnect all connectors.

18. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).

19. Turn the ignition switch OFF.

20. Turn the ignition switch ON (II), and wait 10 seconds.

21. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P2552 indicated?

YES -Check for poor connections or loose terminals at the throttle actuator control module relay, the
throttle actuator control module, and the ECM/PCM. If the ECM/PCM was updated, substitute a known-
good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step 19. If the ECM/PCM was
substituted, go to step 1.

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING.

DTC U0107: LOST COMMUNICATION WITH THROTTLE ACTUATOR CONTROL MODULE

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Check for Temporary DTCs or DTCs with the HDS.

Is DTC U0107 indicated?

YES -Check for poor connections or loose terminals at the throttle body, the throttle actuator control
module relay, the throttle actuator control module, and the ECM/PCM, then go to step 50. If the
connections are OK, go to step 6.

NO -Go to step 4.

4. Start the engine.

5. Check for Temporary DTCs or DTCs with the HDS.

Is DTC U0107 indicated?

YES -Go to step 46.

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
the throttle body, the throttle actuator control module relay, the throttle actuator control module, and the
ECM/PCM.

6. Clear the DTC with the HDS.

7. Turn the ignition switch OFF.

8. Disconnect the intake air duct from the throttle body.

9. Press the accelerator pedal to the floor.
