Diagnostic ProcedureUCS005QU
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “TURBINE REV” while driving. Check the
value changes according to driving speed.
OK or NG

NG >> GO TO 2.
2. CHECK TURBINE REVOLUTION SENSOR (POWER TRAIN REVOLUTION SENSOR)
With CONSULT-II
1. Start engine.
2. Check power supply to turbine revolution sensor (power train revolution sensor) by voltage between TCM
connector terminals. Refer to AT- 1 8 3 , "
Wiring Diagram — AT — MAIN" and AT-177, "Wiring Diagram —
AT — PT/SEN" .
3. If OK, check the pulse when vehicle cruises.
OK or NG
