DTC DEFINITION
DTC DETECTION
CONDITION
DTC SET
CONDITION
POSSIBLE CAUSES
P0705
Multi-Function
switch: prohibited
position
Vehicle is driving
The Transaxle
Control Module
(TCM) detects the
voltage is out of
range when moving
the shift lever from
the
⬙P⬙ position to
the
⬙N⬙ position.
• Multi-Function
Switch
• Harness or
connectors (The
sensor circuit is open
or shorted)
• TCM
DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start the engine and warm it to normal operating temperature.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle & Transfer Case for more information).
NOTE :
• If using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still connected.
Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.
• Using the appropriate diagnostic test tool in this way will help prevent electrical connector terminal damage.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
DIAGNOSIS & TESTING
Diagnostic Procedure
1.
CHECK A/T SOLENOID SIGNAL
• Turn ignition switch on.
• With the scan tool, select view DTC and data stream for A/T.
• Monitor the value of the multi-function switch and compare to the following table.

Do the circuits check OK, and do the reverse lamps also illuminate?
Yes
>>
The transaxle range switch is normal.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
No
>>
Go to the next step.

Does the switch check OK?
Yes
>>
If the test results for the TCM electrical connector is normal, and the test results for the transaxle
assembly is not normal, repair the circuits between the TCM electrical connector and transaxle shift range switch.
No
>>
If the test results for the TCM electrical connector pin 34 and pin 42 are normal, and the test results
for the transaxle range switch pin A8 and A4 are normal, repair the circuit between the TCM electrical
connector pin 34 and transaxle range switch electrical connector pin A8.
If the test results are not normal in one switch position, replace the transaxle range switch. If the test
results are not normal at two or more switch positions, adjust the transaxle range switch before replac-
ing it. After adjusting the transaxle range switch, verify the adjustment with the table. If the test results
are still not normal, replace the transaxle range switch.
