DTC CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
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
ACC PEDAL OPEN : More than 1.0/8
RANGE : "D" position
Driving location : Driving the vehicle uphill (increased engine load) will help maintain the driving conditions required for this test.
With GST
Follow the procedure "With CONSULT".
Diagnosis Procedure
Regarding Wiring Diagram information, refer to TM-126, "Wiring Diagram".
1.CHECK SECONDARY SPEED SENSOR
With CONSULT
Check the pulse when vehicle drive.
2.CHECK POWER AND SENSOR GROUND
5. Check voltage between secondary speed sensor vehicle side harness connector terminal and ground.
3.CHECK HARNESS BETWEEN TCM AND SECONDARY SPEED SENSOR (SENSOR GROUND)
Turn ignition switch OFF.
Disconnect TCM connector.
Check continuity between TCM vehicle side harness connector terminal and ground.
4.CHECK HARNESS BETWEEN TCM AND SECONDARY SPEED SENSOR (PART 1)
Check continuity between TCM vehicle side harness connector terminal and secondary speed sensor vehicle side harness connector terminal.
5.CHECK HARNESS BETWEEN TCM AND SECONDARY SPEED SENSOR (PART 2)
Check continuity between TCM vehicle side harness connector terminal and ground.
6.CHECK HARNESS BETWEEN IPDM E/R AND SECONDARY SPEED SENSOR (POWER) (PART 1)
7.CHECK HARNESS BETWEEN IPDM E/R AND SECONDARY SPEED SENSOR (POWER) (PART 2)
Check continuity between IPDM E/R vehicle side harness connector terminal and ground.
8.CHECK HARNESS BETWEEN TCM AND SECONDARY SPEED SENSOR (SENSOR GROUND) (PART 1)
Turn ignition switch OFF.
Disconnect TCM connector.
Check continuity between TCM vehicle side harness connector terminal and secondary speed sensor vehicle side harness connector terminal.
9.CHECK HARNESS BETWEEN TCM AND SECONDARY SPEED SENSOR (SENSOR GROUND) (PART 2)
Check continuity between TCM vehicle side harness connector terminal and ground.
10.CHECK TCM
11.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
