DTC P0705

BHE050201026W06

DTC P0705 | Transmission range (TR) switch circuit malfunction (short to power supply)
--- | ---
DETECTION CONDITION | • Two or more range signals are input from the TR switch for 12 s or more. Diagnostic support note: • This is a continuous monitor (CCM). • MIL illuminates if TCM detects the above malfunction condition in two consecutive drive cycles. • PENDING CODE is available. • FREEZE FRAME DATA is available. • AT warning light illuminates. • DTC is stored in TCM memory.
POSSIBLE CAUSE | • TCM malfunction • Short to power supply in wiring harness between TR switch terminal A and TCM terminal 1D • Short to power supply in wiring harness between TR switch terminal E and TCM terminal 2C • Short to power supply in wiring harness between TR switch terminal D and TCM terminal 2B • Short to power supply in wiring harness between TR switch terminal G and TCM terminal 2E • Damaged connector between TR switch and TCM • TR switch malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | 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 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.
No | Go to the next step.
3 | VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Turn the ignition switch to the LOCK position. • Disconnect the TCM connector. • Turn the ignition switch to the ON position (engine off). • Inspect each TCM (wiring harness-side) terminal voltage. (See TCM INSPECTION.) – 1D • P position: B+ • Other positions and all ranges: 0 V – 2C • R position: B+ • Other positions and all ranges: 0 V – 2B – N position: B+ – Other positions and all ranges: 0 V – 2E • D range: B+ • Other ranges and all positions: 0 V • Are two or more of the above terminal voltage measurements indicated at the same time when shifting selector lever from P position to D range? | Yes | Go to the next step.
No | • Turn the ignition switch to the LOCK position. • Connect the TCM connector. • Go to the intermittent concern troubleshooting procedure, then go to Step 7. (See INTERMITTENT CONCERN TROUBLESHOOTING.)
4 | INSPECT TR SWITCH CONNECTOR • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect for bent terminals for bending using mirror. • Are the TR switch terminals normal? | Yes | Go to the next step.
No | Repair the terminals or replace the TR switch, then go to Step 7. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION.)
5 | INSPECT TR SWITCH • Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION.) • Is the TR switch normal? | Yes | Go to the next step.
No | Replace the TR switch, then go to Step 7. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION.)
6 | INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Measure the voltage at TR switch (wiring harness-side) terminals A, E, D, and G. • Is there 0 V at the TR switch harness-side connector terminals? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to the next step.
7 | VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED • Turn the ignition switch to the LOCK position. • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the WDS or equivalent. • Turn the ignition switch to the START position (engine on). • Drive the vehicle in each range (P, R, N, and D) for 12 s or more. • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION.)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [RC4A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [RC4A-EL].)
No | DTC troubleshooting completed.
