DTC DETECTION LOGIC

DTC	Trouble diagnosis name	DTC detection condition	Possible causes
P0706	Transmission Range Sensor "A" Circuit Range/Performance	The following diagnosis conditions are met and the position signal is OFF continuously for 15 seconds or more. - Diagnosis condition - TCM power supply voltage: 10 V <TCM power supply voltage <16 V	Harness or connector (Open circuit between transmission position SW and TCM) Transmission position switch Control cable

DTC CONFIRMATION PROCEDURE

1.PREPARATION BEFORE WORK

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

>> GO TO 2.

2.PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch to ON.
2. Shift the selector lever to the entire position from P to 1. (Hold the selector lever at each position for 20 seconds or more.)
3. Check the first trip DTC.

Is "P0706" detected?

YES >> Go to TM, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK CONTROL CABLE

Check the control cable. Refer to TM, "Inspection and Adjustment".

Is the check result normal?

YES >> GO TO 2.

NO >> Adjust the control cable Refer to TM, "Inspection and Adjustment".

2.CHECK POWER CIRCUIT

1. Turn the ignition switch OFF.
2. Disconnect the transmission range switch connector.
3. Turn the ignition switch ON.
4. Check the voltage between the transmission range switch harness connector and ground. 

Is the check result normal?

YES >> GO TO 3.

NO >> GO TO 6.

3.CHECK CIRCUIT BETWEEN TRANSMISSION RANGE SWITCH AND TCM (CHECK 1)

1. Turn the ignition switch OFF.
2. Disconnect the TCM connector. 
3. Check the continuity between the transmission range switch harness connector and the TCM harness connector.   

Is the check result normal?

YES >> GO TO 4.

NO >> Repair or replace the malfunctioning parts.

4.CHECK CIRCUIT BETWEEN TRANSMISSION RANGE SWITCH AND TCM (CHECK 2)

Check the continuity between the transmission range switch harness connector and ground. 

Is the check result normal?

YES >> GO TO 5.

NO >> Repair or replace the malfunctioning parts.

5.CHECK TRANSMISSION RANGE SWITCH

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

Is the check result normal?

YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".

NO >> Repair or replace the malfunctioning parts.

6.CHECK CIRCUIT BETWEEN IPDM E/R AND TRANSMISSION RANGE SWITCH (CHECK 1)

1. Disconnect the IPDM E/R connector.
2. Check the continuity between the IPDM E/R harness connector and the transmission range switch. 

Is the check result normal?

YES >> GO TO 7.

NO >> Repair or replace the malfunctioning parts.

7.CHECK CIRCUIT BETWEEN IPDM E/R AND TRANSMISSION RANGE SWITCH (CHECK 2)

Check the continuity between the IPDM E/R harness connector and ground. 

Is the check result normal?

YES >> GO TO 8.

NO >> Repair or replace the malfunctioning parts.

8.DETECTION OF MALFUNCTION ITEMS

• Check the following items:
• Harness open circuit or short circuit between the ignition switch and IPDM E/R. Refer to PG, "Wiring Diagram - Ignition Power Supply -".
• 10 A fuse (#49, IPDM E/R). Refer to PG, "IPDM E/R Terminal Arrangement".
• IPDM E/R

Is the check result normal?

YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".

Component Inspection (Transmission Range Switch)

1.CHECK TRANSMISSION RANGE SWITCH

Check the continuity between the transmission range switch connector terminals. 

Is the check result normal?

YES >> INSPECTION END

NO >> There is a malfunction of the transmission range switch. Replace the transaxle assembly. Refer to TM, "Removal and Installation".
