CVT

P0705 TRANSMISSION RANGE SWITCH A

Description

- The transmission range switch assembly includes a transaxle case.
- The transaxle range switch detects the selector lever position and sends a signal to the TCM.


CONSULT Reference Value in Data Monitor Mode








On Board Diagnosis Logic

- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "P0705" with CONSULT is detected when TCM does not receive the correct voltage signal (based on the gear position) from the switch.


Possible Cause

- Harness or connectors (transmission range switches circuit is open or shorted.)
- transmission range switch


DTC Confirmation Procedure


CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If "DTC Confirmation Procedure" has been previously performed, always turn ignition switch OFF and wait at least 10 seconds before performing the next test.
After the repair, touch "ERASE" on "SELF-DIAG RESULTS" and then perform the following procedure to confirm the malfunction is eliminated.

WITH CONSULT

1.Turn ignition switch ON. (Do not start engine.)
2.Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT.
3.Start engine.
4.Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.

VEHICLE SPEED: More than 10 km/h (6 MPH)
ENG SPEED: More than 450 rpm
ACC PEDAL OPEN: More than 1.0/8

5.If DTC is detected, go to .

WITH GST

Follow the procedure "WITH CONSULT".

Diagnosis Procedure


1. CHECK TRANSMISSION RANGE SWITCH SIGNALS

With CONSULT
1.Turn ignition switch ON. (Do not start engine.)
2.Select "DATA MONITOR" mode for "TRANSMISSION".
3.Change selector lever to "P", "R", "N", "D" and "L" positions to check the value of "P RANGE SW", "R
RANGE SW", "N RANGE SW", "D RANGE SW" and "L RANGE SW". .





Without CONSULT





1.Turn ignition switch ON. (Do not start engine.)
2.Change selector lever to "P", "R", "N", "D" and "L" positions to check voltage between the CVT unit harness connector terminals and ground.





OK or NG
OK- GO TO 6.
NG- GO TO 2.

2. CHECK TRANSMISSION RANGE SWITCH CIRCUIT

Check the following. If NG, repair or replace damaged parts.
- Harness for short or open between ignition switch and transmission range switch.
- 10A fuse (NO. 51, IPDM E/R)
OK or NG
OK- GO TO 6.
NG- GO TO 3.

3. CHECK HARNESS BETWEEN TCM AND TRANSMISSION RANGE SWITCH

1.Turn ignition switch OFF.
2.Disconnect TCM connector and transmission range switch connector.





3.Check continuity between TCM connector terminals and transmission range switch connector terminals.





4.If OK, check harness for short to ground and short to power.
5.Reinstall any part removed.
OK or NG
OK- GO TO 4.
NG- Repair or replace damaged parts.

4. DETECT MALFUNCTIONING ITEM

Check transmission range switch. .
OK or NG
OK - GO TO 5.
NG- Repair or replace damaged parts.

5. ADJUSTMENT OF CONTROL CABLE

Adjustment of control cable. Adjustments. Check the step 4 after adjusting control cable.
OK or NG
OK - GO TO 6.
NG- Repair or replace damaged parts.

6. CHECK DTC

Perform .
OK or NG
OK-INSPECTION END
NG- GO TO 7.

7. CHECK TCM

1.Check TCM input/output signals. Trouble Diagnosis.
2.If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK-INSPECTION END
NG- 1.Repair or replace damaged parts.
2.Replace the transaxle assembly. Transaxle Assembly.


Component Inspection


TRANSMISSION RANGE SWITCH






1.Change selector lever to various positions to check the continuity between terminals on the transmission range switch and ground.





2.If NG, check continuity with control cable disconnected. (Refer to step 1 above.)
3.If OK, with the control cable disconnected, adjust the control cable. Adjustments .
4.If NG, even when the control cable is disconnected, replace the transaxle assembly. Transaxle Assembly .
