DTC P0705

Transaxle range (TR) switch circuit malfunction (short circuit)

DETECTION CONDITION

• If all conditions below satisfied and 100 s or more have passed, the PCM determines that there is a malfunction.
- Any of D, S, or L range of TR switch ON.
- Engine speed 530 rpm or more.
- P/N position or R position of TR switch ON.
Diagnostic support note:
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle.
• A PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• The HOLD indicator light flashes.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• TR switch malfunction
• Short to power supply between TR switch terminal C and PCM terminal 3E
• Short to power supply between TR switch terminal G and PCM terminal 3H
• Short to power supply between TR switch terminal F and PCM terminal 3K
• Short to power supply between TR switch terminal E and PCM terminal 3N
• Damaged connector between TR switch and PCM
• PCM 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.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2

VERIFY RELATED 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 CONNECTOR

• Turn the ignition switch to the LOCK position.
• Disconnect the TR switch connector.
• Inspect the pins for bent terminals using a mirror.
• Are the TR switch terminals normal?
Yes
Go to the next step.
No
Repair terminals or replace the TR switch, then go to Step 6.
4

INSPECT TR SWITCH CONTINUITY

• Is there continuity between the TR switch (part-side) terminals?
Yes
Go to the next step.
No
Replace the TR switch, then go to Step 6.
5

INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER

• Turn the ignition switch to the ON position (engine off).
• Measure voltage at TR switch (wiring harness-side) terminals C, E, F and G.
• Is the voltage 0 V at the TR switch (wiring harness-side) connector?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to the next step.

VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED

• Make sure to reconnect all the disconnected connectors.
• Clear the DTC from the memory using the WDS or equivalent.
• Run engine at 530 rpm or more.
• Drive the vehicle in each range (D, S, and L) at an engine speed of 530 rpm or more (VSS PID) for 100 s or more.
• Are any DTCs present?
Yes
Replace the PCM, then go to the next step.
No
No concern is detected. Go to the next step.
