DTC P0705 [FN4A-EL]

BME050201030206

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 • 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 | 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. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [FN4A-EL].)
4 | INSPECT TR SWITCH CONTINUITY • Is there continuity between the TR switch (part-side) terminals? (See TRANSAXLE RANGE (TR) SWITCH INSPECTION [FN4A-EL].) | Yes | Go to the next step.
No | Replace the TR switch, then go to Step 6. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [FN4A-EL].)
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.
6 | 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.
(See PCM REMOVAL/INSTALLATION [L3].)
No | No concern is detected. Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [FN4A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [FN4A-EL].)
No | DTC troubleshooting completed.
