id050221801000

DTC P0707

Transaxle range (TR) switch circuit low input

DETECTION CONDITION

•  When all conditions below are satisfied and 100 s or more have passed.

―  Vehicle speed 20 km/h {12 mph} or more

―  Engine speed 530 rpm or more

―  Voltage at TCM terminal U 0.5 V or less

Diagnostic support note:

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle.

•  The PENDING CODE is available if the TCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA is available.

•  The AT warning light illuminates.

•  The DTC is stored in the TCM memory.

POSSIBLE CAUSE

•  TR switch malfunction

•  Short to ground in wiring harness between TR switch terminal C and TCM terminal U

•  TR switch signal and TR switch ground circuits shorted each other

•  TCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Bulletins and/or on-line repair information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT TR SWITCH CONNECTOR • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect for poor connection at TR switch terminals B and C (part-side) (such as damaged/pulled-out pins, corrosion) • Are TR switch terminals normal?	Yes	Go to the next step.
3		No	Repair terminals or replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION[FS5A-EL].)
4	INSPECT TR SWITCH • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect for resistance between TR switch terminals B and C (part-side). • Is the resistance normal? (See TRANSAXLE RANGE (TR) SWITCH INSPECTION[FN4A-EL].)	Yes	Go to the next step.
4		No	Replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION[FS5A-EL].)
5	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection at terminals U and V (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
5		No	Go to the next step.
6	INSPECT TR SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between TR switch terminal C (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness for short to ground, then go to Step 8.
6		No	Go to the next step.
7	INSPECT TR SWITCH CIRCUIT FOR SHORT CIRCUIT • Inspect for continuity between TR switch terminals B and C (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for short circuit, then go to the next step.
7		No	Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0707 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the M-MDS. • Drive the vehicle for 100 s or more under the following conditions: ― Engine speed (RPM PID): 530 rpm or more ― Vehicle speed (VSS PID): 20 km/h {12 mph} or more • Is the PENDING CODE present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION[FS5A-EL].)
8		No	No concern is detected. Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[FS5A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection.
9		No	DTC troubleshooting completed.
