id050208801000

DTC P0707

Transmission range (TR) switch circuit low input (short to ground)

DETECTION CONDITION

•  A signal input from the TR switch to the TCM corresponds to two contact points or more.

Diagnostic support note:

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

•  The AT warning light illuminates if the TCM detects the above malfunction condition during the first drive cycle.

•  PENDING CODE is not available.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the TCM memory.

POSSIBLE CAUSE

•  TR switch misadjustment

•  TCM connector or terminal malfunction

•  Short to power supply in wiring harness between TR switch terminal B and TCM terminal 2O

•  Short to power supply in wiring harness between TR switch terminal C and TCM terminal 2M

•  Short to power supply in wiring harness between TR switch terminal H and TCM terminal 2N

•  Short to power supply in wiring harness between TR switch terminal D and TCM terminal 2K

•  TR switch connector or terminal malfunction

•  TCM malfunction

POSSIBLE CAUSE	• TR switch misadjustment • TCM connector or terminal malfunction • Short to power supply in wiring harness between TR switch terminal B and TCM terminal 2O • Short to power supply in wiring harness between TR switch terminal C and TCM terminal 2M • Short to power supply in wiring harness between TR switch terminal H and TCM terminal 2N • Short to power supply in wiring harness between TR switch terminal D and TCM terminal 2K • TR switch connector or terminal malfunction • TCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded on the repair order?	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 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 CIRCUIT • Connect the TCM connector. • Turn the ignition switch to the ON position. (engine off) • Inspect the voltage between TCM terminal (wiring harness-side) and body GND. ― TCM terminal 2O • P position: B+ • Other positions and all ranges: 0V ― TCM terminal 2M • R position: B+ • Other position and all ranges: 0V ― TCM terminal 2N • N position: B+ • Other position and all range: 0V ― TCM terminal 2K • D range: B+ • Other ranges and all positions: 0V • Are any of following terminal voltage turned on for even a moment while shifting selector lever slowly from P position to D range?	Yes	Go to Step 8.
3		No	Go to the next step.
4	INSPECT TR SWITCH CIRCUIT • Are all terminal voltage 0 V in Step 3?	Yes	Go to Step 8.
4		No	Go to the next step.
5	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the TCM connector. • Inspect for poor connection at TCM terminals 2O, 2K, 2M and 2N (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminal, then go to Step 8.
5		No	Go to the next step.
6	INSPECT TR SWITCH CONNECTOR FOR POOR CONNECTION • Disconnect the TR switch connector. • Inspect for poor connection at TR switch terminals B, C, D and H (part-side) (such as damaged/pulled-out pins, corrosion) • Are TR switch terminals normal?	Yes	Go to the next step.
6		No	Repair terminals or replace the TR switch, then go to Step 8. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
7	INSPECT TR SWITCH • Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION [SJ6A-EL].) • Is the TR switch normal?	Yes	Repair or replace the wiring harness for open circuit, then go to the next step.
7		No	Replace the TR switch, then go to the next step. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
8	VERIFY TROUBLESHOOTING OF DTC P0707 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Warm-up the engine to normal operating temperature. 3. Depress the brake pedal, and shift the selector lever from P to D for 2 s or more. • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
8		No	Go to the next step.
9	VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See AUTOMATIC TRANSMISSION ON-BOARD DIAGNOSTIC FUNCTION [SJ6A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SJ6A-EL].)
9		No	DTC troubleshooting completed.
