NO - Go to step 22.






22. Disconnect PCM connector C (44P).

23. Check for continuity between PCM connector terminal C14 and input shaft (mainshaft) speed sensor connector terminal No. 3.

Is there continuity?
YES - Go to step 24.

NO - Repair open in the wire between the input shaft (mainshaft) speed sensor connector and PCM connector terminal C14, then go to step 40.






24. Connect PCM connector B (44P).

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

26. Measure the voltage between input shaft (mainshaft) speed sensor connector terminals No. 2 and No. 3.

Is there about 5 V?
YES - Go to step 31.

NO - Go to step 27.






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

28. Jump the SCS line with the HDS.

29. Disconnect PCM connector B (44P).

30. Check for continuity between PCM connector terminal B17 and input shaft (mainshaft) speed sensor connector terminal No. 2.

Is there continuity?
YES - Go to step 35.

NO - Repair open in the wire between PCM connector terminal B17 and the input shaft (mainshaft) speed sensor, then go to step 40.






31. Connect the input shaft (mainshaft) speed sensor connector.

32. Clear the DTC with the HDS.

33. Start the engine, and disable the VSA by pressing the VSA OFF switch. Run the vehicle in either 2nd, 3rd, 4th, or 5th gear (not 1st) with the shift lever in S (sequential sportshift mode) at speeds over 12 mph (20 km/h) and an engine speed of 500 rpm or higher, for at least 10 seconds. Slow down and stop the wheels.

34. Monitor the OBD STATUS for P0716 or P0717 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate FAILED?
YES - Replace the input shaft (mainshaft) speed sensor, A/T Input Shaft (Mainshaft) Speed Sensor Replacement then go to step 40.

NO - Go to step 36.


35. Reconnect all connectors.

36. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. How to Troubleshoot A/T Systems

37. Start the engine, and disable the VSA by pressing the VSA OFF switch. Run the vehicle in either 2nd, 3rd, 4th, or 5th gear (not 1st) with the shift lever in S (sequential sportshift mode) at speeds over 12 mph (20 km/h) and an engine speed of 500 rpm or higher, for at least 10 seconds.

39. Monitor the OBD STATUS for P0716 or P0717 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. Service and Repair If any other DTCs were indicated on step 38, go to the indicated DTC's troubleshooting.

NO - Check for poor connections and loose terminals at the input shaft (mainshaft) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 37 and recheck.
