DTC P0705

Transaxle range (TR) switch circuit malfunction (short to ground)

DETECTION CONDITION

•  Two or more range signals are input from TR switch for 100 s or more.

POSSIBLE CAUSE

•  Short to ground in wiring harness between TR switch terminal A and PCM terminal 1N

•  Short to ground in wiring harness between TR switch terminal C and PCM terminal 1J

•  Short to ground in wiring harness between TR switch terminal D and PCM terminal 1S

•  Short to ground in wiring harness between TR switch terminal G and PCM terminal 1L

•  Short to ground in wiring harness between TR switch terminal F and PCM terminal 1P

•  Short to ground in wiring harness between TR switch terminal E and PCM terminal 1K

•  Damaged connector between TR switch and PCM

•  TR switch malfunction

•  PCM malfunction

DTC P0705	Transaxle range (TR) switch circuit malfunction (short to ground)
DETECTION CONDITION	• Two or more range signals are input from TR switch for 100 s or more. ― Engine speed 530 rpm or more Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • A PENDING CODE is not available. • FREEZE FRAME DATA is available. • The O/D OFF indicator light illuminates. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Short to ground in wiring harness between TR switch terminal A and PCM terminal 1N • Short to ground in wiring harness between TR switch terminal C and PCM terminal 1J • Short to ground in wiring harness between TR switch terminal D and PCM terminal 1S • Short to ground in wiring harness between TR switch terminal G and PCM terminal 1L • Short to ground in wiring harness between TR switch terminal F and PCM terminal 1P • Short to ground in wiring harness between TR switch terminal E and PCM terminal 1K • Damaged connector between TR switch and PCM • TR switch malfunction • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service 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? • Turn the ignition switch to the ON position (engine OFF). • Inspect PCM terminal voltages. (See PCM INSPECTION[L3].) ― PCM terminal 1N • P position: 0 V • Other positions and all ranges: B+ ― PCM terminal 1J • R position: 0 V • Other positions and all ranges: B+ ― PCM terminal 1S • N position: 0 V • Other positions and all ranges: B+ ― PCM terminal 1L • D range: 0 V • Other ranges and all positions: B+ ― PCM terminal 1P • 2 range: 0 V • Other ranges and all positions: B+ ― PCM terminal 1K • 1 range: 0 V • Other ranges and all position: B+ • Are two or more of following terminal voltage at the same time when shifting selector lever from P position to 1 range?	Yes	Go to the next step.
3		No	Go to intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING[L3].)
4	INSPECT TR SWITCH CONNECTOR • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect for bent terminals of pins using mirror. • Are 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[GF4AX-EL].)
5	INSPECT TR SWITCH CIRCUIT MALFUNCTION • Turn the ignition switch to the ON position (engine OFF). • Does PCM terminal voltage change from B+ to 0 V when 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 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[GF4AX-EL].)	Yes	Go to Step 8.
6		No	Replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION[GF4AX-EL].)
7	INSPECT TR SWITCH CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between PCM terminals (wiring harness-side) and body ground. ― PCM terminal: 1J, 1K, 1L, 1N, 1P, 1S • Is there continuity?	Yes	Repair or replace the wiring harness, then go to the next step.
7		No	Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using M-MDS. • Drive vehicle in each range (P, R, N, D, 2, and 1) for 100 s or more. • Is same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[L3].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE[GF4AX-EL].) • Is there any DTC present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[GF4AX-EL].)
9		No	DTC troubleshooting completed.
