DTC CONFIRMATION PROCEDURE
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “Data Monitor” mode for “TRANSMISSION”.
3. Make sure that output voltage of line temperature sensor is within the range below.
4. Start engine and wait for at least 5 consecutive seconds.
With GST
Follow the procedure “With CONSULT-III”.
Is
“P0845 TR PRS SENS/B CIRC” detected?
YES >> Go to TM-80, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003849012
1.CHECK INPUT SIGNAL
1. Start engine.
2. Check voltage between TCM connector terminal and ground.
Is the inspection result normal?
YES >> GO TO 8.
NO >> GO TO 2.
2.CHECK SENSOR POWER AND SENSOR GROUND
Check voltage between TCM connector terminals.
