DTC P0706 | Transaxle range (TR) switch circuit malfunction (open/ground short circuit)
--- | ---
DETECTION CONDITION | • No range signal is input from TR switch for 100 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. • FREEZE FRAME DATA is available. • AT warning light does not indication. • DTC is stored in TCM memory.
POSSIBLE CAUSE | • TR switch malfunction. • TR switch misadjustment • Short to ground between TR switch terminal A and TCM terminal 2B • Short to ground between TR switch terminal E and TCM terminal 1W • Short to ground between TR switch terminal D and TCM terminal 1T • Short to ground between TR switch terminal G and TCM terminal 1Z • Open circuit between TR switch terminal A and TCM terminal 2B • Open circuit between TR switch terminal E and TCM terminal 1W • Open circuit between TR switch terminal D and TCM terminal 1T • Open circuit between TR switch terminal G and TCM terminal 1Z • Open circuit between TR switch terminal C and IG key (ACC) • Short to ground between TR switch terminal C and IG key (ACC) • Damaged connector between TR switch and TCM. • TCM 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 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Turn ignition key to OFF. • Check for poor connection (damaged pulled-out terminals, corrosion, etc.). • Are terminals okay? | Yes | Go to next step.
No | Repair terminals, then go to Step 12.
4 | INSPECT TR SWITCH CIRCUIT • Connect voltmeter to TCM. • Inspect TCM terminal voltage. - TCM terminal 2B • P position: B+ • Other positions and all ranges: 0V - TCM terminal 1W • R position: B+ • Other position and all ranges: 0V - TCM terminal 1T • N position: B+ • Other position and all range: 0V - TCM terminal 1Z • D range: B+ • Other ranges and all positions: 0V • Are any of following terminal voltage turned on for even a moment while shifting selector lever slowly from P position to D range? | Yes | Adjust TR switch, then go to Step 12. (See TRANSAXLE RANGE (TR) SWITCH ADJUSTMENT [JA5AX-EL].)
No | Go to next step.
5 | INSPECT TR SWITCH CONNECTOR FOR POOR CONNECTION • Turn ignition key to OFF. • Check for poor connection (damaged pulled-out terminals, corrosion, etc.). • Are terminals okay? | Yes | Go to next step.
No | Repair terminals, then go to Step 12.
6 | INSPECT TR SWITCH CIRCUIT • Disconnect TR switch connector. • Connect voltmeter to TCM. • Turn ignition key to ON (engine OFF). • Connect harness side connector power line and signal line using jumper wire - P position: C and A - R position: C and E - N position: C and D - D range: C and G • Inspect if terminal voltage changes. - 0V to B+ • Does terminal voltage change? | Yes | Go to next step.
No | Go to Step 9.
7 | INSPECT TR SWITCH FOR OPEN CIRCUIT • Turn ignition key to OFF. • Inspect continuity between TR switch terminals (part side). - P position: C and A - R position: C and E - N position: C and D - D range: C and G • Is there continuity between TR switch terminals (part side)? (See TRANSAXLE RANGE (TR) SWITCH INSPECTION [JA5AX-EL].) | Yes | Go to Step 12.
No | Replace TR switch, then go to Step 12. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5AX-EL].)
8 | INSPECT TR SWITCH POWER CIRCUIT FOR OPEN CIRCUIT • Check voltage at TR switch terminal C (harness-side). • Is there B+ at TR switch terminal C (harness-side)? | Yes | Go to next step.
No | Inspect main fuse. • If okay, repair or replace wiring, then go to Step 12.
9 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn ignition key to OFF. • Check for poor connection (damaged pulled-out terminals, corrosion, etc.). • Are terminals okay? | Yes | Go to next step.
No | Repair terminals, then go to Step 12.
10 | INSPECT TR SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT • Check continuity between TR switch terminals (harness-side) and TCM terminals (harness-side). - P position: A and 2B - R position: E and 1W - N position: D and 1T - D range: G and 1Z • Is there continuity? | Yes | Go to next step.
No | Repair or replace harness, then go to Step 12.
11 | INSPECT TR SWITCH CIRCUIT FOR SHORT TO GROUND • Check continuity between TCM terminals (harness-side) and body ground. - P position: 2B and body ground - R position: 1W and body ground - N position: 1T and body ground - D range: 1Z and body ground • Is there continuity? | Yes | Go to next step.
No | Repair or replace harness, then go to next step.
12 | VERIFY TROUBLESHOOTING OF DTC P0706 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Drive vehicle in each range (P, R, N, and D) for 100 s or more. • Is there pending code present? | Yes | Replace TCM, then go to next step. (See TCM REMOVAL/INSTALLATION [JA5AX-EL].)
No | Go to next step.
13 | 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.
