DTC P0705 [JA5AX-EL]

id050206809900

DTC P0705 | Transaxle range (TR) switch circuit malfunction (short circuit)
--- | ---
DETECTION CONDITION | • Two or more range signals are input from TR switch for 5 s or more. Diagnostic support note: • This is a continuous monitor (CCM). • MIL illuminates if TCM detects the above malfunction conditions in two consecutive drive cycles. • PENDING CODE is available above malfunction condition during first drive cycle. • FREEZE FRAME DATA is available. • AT warning light does not indication. • DTC is stored in TCM memory.
POSSIBLE CAUSE | • TCM malfunction. • Short to power between TR switch terminal A and TCM terminal 2B • Short to power between TR switch terminal E and TCM terminal 1W • Short to power between TR switch terminal D and TCM terminal 1T • Short to power between TR switch terminal G and TCM terminal 1Z • Damaged connector between TR switch and TCM • TR switch 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 and/or on-line repair information 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 | VERIFY CURRENT INPUT SIGNAL STATUS-IS CONCERN INTERMITTENT OR CONSTANT? • Connect volt meter to TCM. • Turn ignition key to ON (engine OFF). • Inspect TCM terminal voltages. (See TCM INSPECTION [JA5AX-EL].) - TCM terminal 2B • P position: B+ • Other positions and all ranges: 0V - TCM terminal 1W • R position: B+ • Other positions and all ranges: 0V - TCM terminal 1T - N position: B+ - Other positions and all ranges: 0V - TCM terminal 1Z • D range: B+ • Other ranges and all positions: 0V • Are two or more of following terminal voltage at the same time when shifting selector lever from P position to D range? | Yes | Go to next step.
No | Go to intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [L8, LF, L3].)
4 | INSPECT TR SWITCH CONNECTOR • Turn ignition key OFF. • Disconnect TR switch connector. • Inspect bent terminals of pins using mirror. • Are TR switch terminals okay? | Yes | Go to next step.
No | Repair terminals or replace TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5AX-EL].)
5 | INSPECT TR SWITCH CIRCUIT MALFUNCTION • Connect voltmeter to TCM. • Turn ignition key to ON (engine OFF). • Does TCM terminal voltage change from B+ to 0V when TR switch connector is disconnected? | Yes | Go to next step.
No | Go to Step 7.
6 | INSPECT TR SWITCH CONTINUITY • Turn ignition key to OFF. • Disconnect TR switch connector. • Inspect TR switch for continuity in positions/ranges failed in Step 4. • Is there continuity between TR switch terminals (part side)? (See TRANSAXLE RANGE (TR) SWITCH INSPECTION [JA5AX-EL].) | Yes | Go to Step 8.
No | Replace TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5AX-EL].)
7 | INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER • Turn ignition key to ON (engine OFF). • Measure voltage at TR switch terminal A, E, D, G, I, and F (harness-side). • Is there 0 V at TR switch harness side connector? | Yes | Go to next step.
No | Repair or replace wiring, then go to next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Turn ignition key to on (engine off). • Drive vehicle in each range (P, R, N, and D) for 5 s or more. • Is same DTC present? | Yes | Replace TCM, then go to next step. (See TCM REMOVAL/INSTALLATION [JA5AX-EL].)
No | Go to next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5AX-EL].) • Is there any DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
