P0705

Description

- The transmission range switch is installed to upper part of transaxle case.
- The transmission range switch detects the selector lever position and sends a signal to the TCM.


CONSULT Reference Value








On Board Diagnosis Logic

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


Possible Cause

- Harness or connectors (The transmission range switch 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.

1.Turn ignition switch ON.
2.Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT.
3.Read out "P", "R", "N", "D" and "L" position switches moving selector lever to each position.





Without CONSULT
1.Turn ignition switch ON.
2.Check voltage between TCM connector terminals and ground while moving selector lever through each position.





OK or NG
OK- GO TO 5.
NG- GO TO 2.

2. CHECK TRANSMISSION RANGE SWITCH

1.Turn ignition switch OFF.
2.Disconnect transmission range switch harness connector.





3.Check continuity between transmission range switch harness connector terminals.





OK or NG
OK- GO TO 4.
NG- GO TO 3.

3. CHECK CONTROL CABLE ADJUSTMENT

Check transmission range switch again with control cable disconnected from manual shaft of A/T assembly.
Refer to test group 2.
OK or NG
OK- Adjust control cable. Shift Control System.

Component Inspection


TRANSMISSION RANGE SWITCH






1.Check continuity between transmission range switch harness connector terminals.










2.If NG, check again with control cable (2) disconnected from manual shaft of CVT assembly. Refer to step 1.
(1): Manual shaft (A): Lock nut
3.If OK on step 2, adjust control cable (2). Shift Control System.
4.If NG on step 2, remove transmission range switch from CVT
and check continuity of transmission range switch terminals.
Refer to step 1.
5.If OK on step 4, adjust transmission range switch. CVT Shift Control System.
6.If NG on step 4, replace transmission range switch. Service and Repair.
