DTC P0707 [FN4A-EL]

B3E050219090W08

DTC P0707 | Transaxle range (TR) switch circuit low input
--- | ---

DETECTION CONDITION

• When all conditions below are satisfied and 100 s or more have passed.

  - Vehicle speed 20 km/h {12 mph} or more
  - Engine speed 530 rpm or more
  - Voltage at PCM terminal 1X (Z6)/1S (LF) below 0.5 V

Diagnostic support note:
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
• A PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• The AT warning light illuminates.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE | • TR switch malfunction • Short to ground in wiring harness between TR switch terminal C and PCM terminal 1X (Z6)/1S (LF) • TR switch signal and TR switch ground circuits shorted each other • 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 for poor connection at TR switch terminals B and C (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 TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION.)

INSPECT TR SWITCH

• Turn the ignition switch to the LOCK position.
• Disconnect the TR switch connector.
• Inspect for resistance between TR switch terminals B and C (part-side).
• Is the resistance normal?
(See TRANSAXLE RANGE (TR) SWITCH INSPECTION.)

Yes

Go to the next step.

No | Replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION.)
5 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Disconnect the PCM connector. • Inspect for poor connection at terminals 1X (Z6)/1S (LF) and 1AN(Z6)/1AA (LF) (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 8.
No | Go to the next step.
6 | INSPECT TR SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between TR switch terminal C (wiring harness-side) and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness for short to ground, then go to Step 8.
No | Go to the next step.
7 | INSPECT TR SWITCH CIRCUIT FOR SHORT CIRCUIT • Inspect for continuity between TR switch terminals B and C (wiring harness-side). • Is there continuity? | Yes | Repair or replace the wiring harness for short circuit, then go to the next step.
No | Go to the next step.

VERIFY TROUBLESHOOTING OF DTC P0707 COMPLETED

• Make sure to reconnect all the disconnected connectors.
• Clear the DTC from the memory using the WDS or equivalent.
• Drive the vehicle for 100 s or more under the following conditions:

  - Engine speed (RPM PID): 530 rpm or more
  - Vehicle speed (VSS PID): 20 km/h {12 mph} or more

• Is the PENDING CODE present?

Yes

Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [ZJ, Z6].)
(See PCM REMOVAL/INSTALLATION [LF].)

No | No concern is detected. Go to the next step.
9 | 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.
No | DTC troubleshooting completed.
