RE0F08B

DTC P0705 PARK/NEUTRAL POSITION SWITCH





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




CONSULT-III Reference Value in Data Monitor Mode









On Board Diagnosis Logic
- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "P0705 PNP SW/CIRC" with CONSULT-III is detected when TCM does not receive the correct voltage signal (based on the gear position) from the switch.




Possible Cause
- Harness or connectors
(PNP switches circuit is open or shorted.)
- PNP 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-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
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 "Diagnosis Procedure".

WITH GST
Follow the procedure "WITH CONSULT-III".




Wiring Diagram - CVT - PNP/SW






TCM TERMINALS AND REFERENCE VALUES
Refer to TCM Terminal And Reference Value .




Diagnosis Procedure
1. CHECK PNP SW SIGNALS
With CONSULT-III
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". Refer to "CONSULT-III Reference Value in Data Monitor Mode".







Without CONSULT-III





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 PNP SWITCH CIRCUIT
Check the following. If NG, repair or replace damaged parts.
- Harness for short or open between ignition switch and PNP 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 PNP SWITCH
1. Turn ignition switch OFF.
2. Disconnect TCM connector and PNP switch connector.





3. Check continuity between TCM connector terminals and PNP 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 PNP switch. Refer to "Component Inspection".
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5.ADJUSTMENT OF CONTROL CABLE
Adjustment of control cable. Refer to CVT RE0F08B. 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 "DTC Confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >> GO TO 7.
7.CHECK TCM
1. Check TCM input/output signals. Refer to TCM Terminal And Reference Value.
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. Refer to Transaxle Assembly.




Component Inspection

PNP SWITCH
1. Change selector lever to various positions to check the continuity between terminals on the PNP 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. Refer to CVT RE0F08B CVT RE0F08B,
.
4. If NG, even when the control cable is disconnected, replace the transaxle assembly. Refer to Transaxle Assembly .
