DTC P0705 [JA5A-EL]


DTC P0705	Transaxle range (TR) switch circuit malfunction (short circuit)
DETECTION CONDITION	• If two or more range signals are input from TR switch for 5 s or more, the TCM determines that there is a malfunction. Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the TCM detects the above malfunction conditions in two consecutive drive cycles. • PENDING CODE is available above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The HOLD indicator light flashes. • The DTC is stored in the TCM memory.
POSSIBLE CAUSE	• TCM malfunction. • Short to power supply in wiring harness between TR switch terminal A and TCM terminal 2B • Short to power supply in wiring harness between TR switch terminal E and TCM terminal 1W • Short to power supply in wiring harness between TR switch terminal D and TCM terminal 1T • Short to power supply in wiring harness between TR switch terminal G and TCM terminal 1Z • Short to power supply in wiring harness between TR switch terminal I and TCM terminal 1AA • Short to power supply in wiring harness between TR switch terminal F and TCM terminal 2C • Damaged connector between TR switch and TCM • TR switch malfunction


STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME PID 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.
2		No	Go to the next step.
3	VERIFY CURRENT INPUT SIGNAL STATUS-IS CONCERN INTERMITTENT OR CONSTANT? • Connect volt meter to TCM. • Turn the ignition switch to the ON position (engine off). • Inspect the TCM terminal voltage. (See TCM INSPECTION [JA5A-EL] (VIN: JMZ LW19J7# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J# 300001-301513).) (See TCM INSPECTION [JA5A-EL] (VIN: JM0 LW10J300 301406-, JMZ LW69J7# 307683-, JM8 LW28J# 301514-, JM8 LW28A# 301514- (Assumed)).) - TCM terminal 2B • P position: B+ • Other positions and all ranges: 0 V - TCM terminal 1W • R position: B+ • Other positions and all ranges: 0 V - TCM terminal 1T - N position: B+ - Other positions and all ranges: 0 V - TCM terminal 1Z • D range: B+ • Other ranges and all positions: 0 V - TCM terminal 1AA • S range: B+ • Other ranges and all positions: 0 V - TCM terminal 2C • L range: B+ • Other ranges and all position: 0 V • Are two or more of following terminal voltage at the same time when shifting selector lever from the P position to L range?	Yes	Go to the next step.
3		No	Go to the intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [AJ].)
4	INSPECT TR SWITCH CONNECTOR • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect the pins for bent terminals using a mirror. • Are the TR switch terminals normal?	Yes	Go to the next step.
4		No	Repair the terminals or replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5A-EL].)
5	INSPECT TR SWITCH CIRCUIT MALFUNCTION • Turn the ignition switch to the ON position (engine off). • Does the TCM terminal voltage change from B+ to 0 V when the TR switch connector is disconnected?	Yes	Go to the next step.
5		No	Go to Step 7.
6	INSPECT TR SWITCH CONTINUITY • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect the TR switch for continuity in positions/ranges failed in Step 4. • Is there continuity between the TR switch terminals (part side)? (See TRANSAXLE RANGE (TR) SWITCH INSPECTION [JA5A-EL].)	Yes	Go to Step 8.
6		No	Replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5A-EL].)
7	INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Measure the voltage at TR switch terminal A, E, D, G, I, and F (wiring harness-side). • Is there 0 V at the TR switch wiring harness-side connector?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness, then go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the WDS or equivalent. • Turn the ignition switch to the ON position (engine off). • Drive the vehicle in each range (P, R, N, D, S, and L) for 5 s or more. • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [JA5A-EL].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [JA5A-EL].)
9		No	DTC troubleshooting completed.
