DTC CONFIRMATION PROCEDURE

CAUTION:
Be careful of the driving speed

.

1.PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION

1. Start the engine.

2. Maintain the following conditions.

Accelerator pedal position : 0.0/8 Brake pedal : Depressed
Vehicle speed : 0 km/h (0 MPH)

3. Shift the selector lever through entire positions from “P” to “L”. (Hold the selector lever at each position for 10 seconds or more.)
4. Check the first trip DTC.

Is “P0705” detected? YES >> Go to TM-394, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK TCM INPUT SIGNALS

With CONSULT-III

1. Turn ignition switch ON.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Select “D POSITION SW”, “N POSITION SW”, “R POSITION SW”, “P POSITION SW” and “L POSITION SW”.

4. Shift the selector lever through entire positions from “P” to “L” and check ON/OFF of each monitor item.

Without CONSULT-III.

1. Turn the ignition switch OFF.

2. Disconnect the TCM connector.

3. Turn ignition switch ON.

4. Shift the selector lever from “P” to “L” and check the voltage between the TCM harness connector terminal and the ground.

Is the check result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO-1 [“D POSITION SW” is “ON” when selector is not in “D” position. (Or connector terminal 4 is at power voltage.)]>>GO TO 2.

NO-2 [“N POSITION SW” is “ON” when selector is not in “N” position. (Or connector terminal 5 is at power voltage.)]>>GO TO 4.

NO-3 [“R POSITION SW” is “ON” when selector is not in “R” position. (Or connector terminal 6 is at power voltage.)]>>GO TO 6.

NO-4 [“P POSITION SW” is “ON” when selector is not in “P” position. (Or connector terminal 7 is at power voltage.)]>>GO TO 8.

NO-5 [“L POSITION SW” is “ON” when selector is not in “L” position. (Or connector terminal 2 is at power voltage.)]>>GO TO 10.

2.CHECK D POSITION SW CIRCUIT (PART 1)

1. Turn the ignition switch OFF.

2. Disconnect the TCM connector.

3. Check the continuity between the TCM harness connector terminals.

Is the check result normal? YES >> GO TO 3.

NO >> Repair or replace the malfunctioning parts.

3.CHECK D POSITION SW CIRCUIT (PART 2)

1. Disconnect the transmission position switch connector.

2. Turn ignition switch ON.

3. Check the voltage between the TCM harness connector and ground.

Is the check result normal? YES >> GO TO 12.

NO >> Repair or replace the malfunctioning parts.

4.CHECK N POSITION SW CIRCUIT (PART 1)

1. Turn the ignition switch OFF.

2. Disconnect the TCM connector.

3. Check the continuity between the TCM harness connector terminals.

Is the check result normal? YES >> GO TO 5.

NO >> Repair or replace the malfunctioning parts.

5.CHECK N POSITION SW CIRCUIT (PART 2)

1. Disconnect the transmission position switch connector.

2. Turn ignition switch ON.

3. Check the voltage between the TCM harness connector and ground.

Is the check result normal? YES >> GO TO 12.

NO >> Repair or replace the malfunctioning parts.

6.CHECK P POSITION SW CIRCUIT (PART 1)

1. Turn the ignition switch OFF.

2. Disconnect the TCM connector.

3. Check the continuity between the TCM harness connector terminals.

Is the check result normal? YES >> GO TO 7.

NO >> Repair or replace the malfunctioning parts.

7.CHECK P POSITION SW CIRCUIT (PART 2)

1. Disconnect the transmission position switch connector.

2. Turn ignition switch ON.

3. Check the voltage between the TCM harness connector and ground.

Is the check result normal? YES >> GO TO 12.

NO >> Repair or replace the malfunctioning parts.

8.CHECK R POSITION SW CIRCUIT (PART1)

1. Turn the ignition switch OFF.

2. Disconnect the TCM connector.

3. Check the continuity between the TCM harness connector terminals

Is the check result normal? YES >> GO TO 9.

NO >> Repair or replace the malfunctioning parts.

9.CHECK R POSITION SW CIRCUIT (PART 2)

1. Disconnect the transmission position switch connector.

2. Turn ignition switch ON.

3. Check the voltage between the TCM harness connector and ground.

Is the check result normal? YES >> GO TO 12.

NO >> Repair or replace the malfunctioning parts.

10.CHECK 1: L POSITION SWITCH CIRCUIT (PART 1)

1. Turn the ignition switch OFF.

2. Disconnect the TCM connector.

3. Check the continuity between the TCM harness connector terminals.

Is the check result normal? YES >> GO TO 11.

NO >> Repair or replace the malfunctioning parts.

11.CHECK 2: L POSITION SWITCH CIRCUIT (PART 2)

1. Disconnect the transmission position switch connector.

2. Turn ignition switch ON.

3. Check the voltage between the TCM harness connector and ground.

Is the check result normal? YES >> GO TO 12.

NO >> Repair or replace the malfunctioning parts.

12.CHECK TRANSMISSION RANGE SWITCH

Check the transmission range switch. Refer to TM-398, "Component Inspection (Transmission Range Switch)".

Is the check result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO >> Repair or replace the malfunctioning parts.

Component Inspection (Transmission Range Switch)

1.CHECK TRANSMISSION RANGE SWITCH

Check the continuity between the transmission range switch connector terminals.
