id0502a1801000

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 above. - Engine speed 530 rpm or above. - Voltage at PCM terminal 1X is below 0.5 V. Diagnostic support note: • This is a continuous monitor (CCM). • MIL illuminates if PCM detects the above malfunction condition during first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • HOLD indicator light flashes. • DTC is stored in the PCM memory.
POSSIBLE CAUSE | • TR switch malfunction • Short to ground between TR switch terminal C and PCM terminal 1X • TR switch signal and TR switch ground circuits are shorted to each other • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME PID DATA been recorded? | Yes | Go to next step.
No | Record FREEZE FRAME PID DATA on repair order, then go to next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Check for related Service Bulletins availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to available repair information. • If vehicle is not repaired, go to next step.
No | Go to next step.
3 | INSPECT TR SWITCH CONNECTOR • Turn ignition key OFF. • Disconnect TR switch connector. • Inspect for bent terminals of TR switch terminals B and C (part-side). • Are TR switch terminals normal? | Yes | Go to next step.
No | Repair terminals or replace TR switch, then go to Step 7. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [FN4A-EL].)
4 | INSPECT TR SWITCH • Turn the ignition switch off. • Disconnect TR switch connector. • Inspect for resistance between TR switch terminals B and C (part-side). • Is resistance normal? (See TRANSAXLE RANGE (TR) SWITCH INSPECTION [FN4A-EL].) | Yes | Go to next step.
No | Adjust TR switch, then go to Step 7. (See TRANSAXLE RANGE (TR) SWITCH ADJUSTMENT [FN4A-EL].)
5 | INSPECT TR SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Disconnect PCM connector • Check for continuity between TR switch terminal C (harness-side) and body ground. • Is there continuity? | Yes | Repair or replace harness for short to ground, then Go to step 7.
No | Go to next step.
6 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Disconnect PCM connector. • Check for poor connection at terminals 1X and 1AN (damaged/pulled-out pins, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace terminal, then Go to step 9.
No | Go to next step.
7 | INSPECT TR SWITCH CIRCUIT FOR SHORT • Check for continuity between TR switch terminals B and C (harness-side). • Is there continuity? | Yes | Repair or replace harness for short, then go to next step.
No | Go to next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0707 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Drive vehicle for 100 s or more under following conditions. - Engine speed (RPM PID) 530 rpm or above - Vehicle speed (VSS PID) 20 km/h {12 mph} or above • Is pending code present? | Yes | Replace PCM, then go to next step. (See PCM REMOVAL/INSTALLATION.)
No | No concern is detected. Go to next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [FN4A-EL].) • Are any DTCs present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
