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.
- 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.
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.
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)?
Yes
Go to Step 8.
No
Replace TR switch, then go to Step 8.
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.
No
Go to next step.
9
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to applicable DTC inspection.
No
Troubleshooting completed.
