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.
– 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.
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.
5

INSPECT TR SWITCH

• Inspect the TR switch.
• Is the TR switch normal?
Yes
Go to the next step.
No
Replace the TR switch, then go to Step 7.
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.
No
Go to the next step.
8

VERIFY AFTER REPAIR PROCEDURE

• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
