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 1AS 0.5 V or less
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 1AS
• 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.
4

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?
Yes
Go to the next step.
No
Replace the TR switch, then go to Step 8.
5

INSPECT PCM CONNECTOR FOR POOR CONNECTION

• Disconnect the PCM connector.
• Inspect for poor connection at terminals 1AS and 1AG (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.
8

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.
No
No concern is detected. Go to the next step.
9

VERIFY AFTER REPAIR PROCEDURE

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