TURBINE REVOLUTION SENSOR

Data are reference value and are measured between each terminal and ground.
Diagnostic ProcedureBCS0012H
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
OK >> GO TO 8.
NG >> GO TO 2.
2. CHECK TURBINE 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 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.

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.
6. CHECK HARNESS BETWEEN TCM AND TURBINE REVOLUTION SENSOR (POWER)
1. Turn ignition switch OFF.
2. Disconnect the turbine revolution sensor (power train revolution sensor) harness connector.
3. Check continuity between TCM connector terminals and turbine
revolution sensor (power train revolution sensor) harness con-
nector terminal. Refer to AT- 4 2 , "
Circuit Diagram" and AT- 1 5 8 ,
"Wiring Diagram — AT — MAIN" .
4. If OK, check harness for short to ground and short power.
5. Reinstall any part removed.
OK or NG
OK >> 10A fuse (No.83, located in the IPDM E/R) or ignition switch are malfunctioning.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
7. CHECK HARNESS BETWEEN TCM AND TURBINE REVOLUTION SENSOR (SENSOR GROUND)
1. Turn ignition switch OFF.
2. Disconnect the turbine revolution sensor (power train revolution sensor) harness connector.
3. Check continuity between TCM connector terminal and turbine
revolution sensor (power train revolution sensor) harness con-
nector 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.

CAN COMMUNICATION LINEPFP:31940
DescriptionBCS0012P
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicBCS0012Q
Diagnostic trouble code “CAN COMM CIRCUIT” with CONSULT-II or 12th judgement flicker without CON-
SULT-II is detected when TCM cannot communicate to other control units.
Possible CauseBCS0012R
Harness or connector
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureBCS0012S
CAUTION:
If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Wait at least 6 seconds or start engine and wait for at least 6
seconds.
4. If DTC is detected, go to AT- 1 3 5 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Turn ignition switch ON.
2. Wait at least 6 seconds or start engine and wait at least 6 seconds.
3. Perform self-diagnosis. Refer to AT- 7 6 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT- 1 3 5 , "
Diagnostic Procedure" .
