DTC P0707 [SJ6A-EL]

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

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.
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.
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.
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.
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.
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.
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.
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].)
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].)
No | DTC troubleshooting completed.
