Diagnosis Procedure
INFOID:0000000005928808
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
3. Start vehicle and read out the value of “VSP SENSOR”.
OK or NG
OK >> GO TO 8.
NG >> GO TO 2.
2. CHECK SECONDARY SPEED SENSOR
With CONSULT-III
1. Start engine.
2. Check power supply to secondary speed sensor by voltage between TCM connector terminals 10, 19 and 42. Refer to CVT-37, "
Circuit Diagram" .
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 the secondary speed sensor harness connector.
3. Turn ignition switch ON.

3. Check continuity between TCM connector terminals and sec-
ondary speed sensor harness connector terminal. Refer to CVT-
37, "Circuit Diagram" .
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> 10 A fuse (No. 49, 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 SECO NDARY SPEED SENSOR (SENSOR GROUND)
1. Turn ignition switch OFF.
2. Disconnect TCM connector and secondary speed sensor harness connector.
3. Check continuity between TCM connector terminal and second- ary speed sensor harness connector terminal.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 8.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
8.CHECK DTC
Perform CVT-76, "
DTC Confirmation Procedure" .
OK or NG
OK >> INSPECTION END
NG >> GO TO 9.
9.CHECK TCM
1. Check TCM input/output signals. Refer to CVT-46, "
TCM Terminal and Reference Value" .
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> INSPECTION END
NG >> Repair or replace damaged parts.
