Diagnostic ProcedureBCS0010L
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 “VHCL/S SE-A/T” while driving.
Check the value changes according to driving speed.
OK or NG
OK >> GO TO 8.
NG >> GO TO 2.
2. CHECK REVOLUTION SENSOR
With CONSULT-II
1. Start engine.
2. Check power supply to revolution sensor by voltage between TCM connector terminals. Refer to AT- 1 5 8 ,
"Wiring Diagram — AT — MAIN" .
3. If OK check the pulse when vehicle cruises.
OK or NG
OK >> GO TO 8.
NG >> GO TO 3.

3. CHECK POWER AND SENSOR GROUND
1. Turn ignition switch OFF.
2. Disconnect revolution sensor harness connector.
3. Turn ignition switch ON. (Do not start engine.)
4. Check voltage between revolution sensor harness connector
terminals.
5. Check voltage between revolution sensor harness connector
terminal and ground.
6. If OK, check harness for short to ground and short power.
7. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG - 1 >> Battery voltage is not supplied between terminals 1 and 3, terminals 1 and ground: GO TO 6.
NG - 2 >> Battery voltage is not supplied between terminals 1 and 3 only: GO TO 7.
4. CHECK HARNESS BETWEEN TCM AND REVOLUTION SENSOR
1. Turn ignition switch OFF.
2. Disconnect TCM connector and revolution sensor harness connector.
3. Check continuity between TCM connector terminal and revolu-
tion sensor harness connector terminal.
4. If OK, check harness for short to ground and short power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 5.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
5. CHECK TCM
1. Check TCM input/output signals. Refer to AT- 6 4 , "
TCM Terminals and Reference Value" .
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> GO TO 8.
NG >> Repair or replace damaged parts.
