DTC P2709 [FS5A-EL]


DTC P2709	Shift solenoid F malfunction (electrical)
DETECTION CONDITION	• If TCM detects either of the following conditions while driving in 5GR at D range, the TCM determines that shift solenoid F circuit has a malfunction. - Shift solenoid F voltage stuck at B+ after engine start - Shift solenoid F voltage stuck at 0 V after engine start Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the TCM detects the above malfunction conditions during the first drive cycle. • The PENDING CODE is available if the TCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The AT warning light illuminates. • The DTC is stored in the TCM memory.
POSSIBLE CAUSE	• Shift solenoid F malfunction • Short to ground in wiring harness between transaxle connector (secondary) terminal B and TCM terminal 1J • Short to power supply in wiring harness between transaxle connector (secondary) terminal B and TCM terminal 1J • Open circuit in wiring harness between shift solenoid F terminal A and transaxle connector (secondary) terminal B • Open circuit in wiring harness between transaxle connector (secondary) terminal B and TCM terminal 1J • Damaged connector between shift solenoid F and TCM • TCM malfunction


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 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	INSPECT TRANSAXLE CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the transaxle connector (secondary). • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is the connection normal?	Yes	Go to the next step.
3		No	Repair or replace the connector and/or terminals, then go to Step 11.
4	INSPECT RESISTANCE • Inspect the resistance between transaxle connector (secondary) terminal B (transaxle case side) and body ground. • Is the resistance within 10.9-26.2 ohms? (See Resistance Inspection (On-Vehicle Inspection).)	Yes	Go to Step 7.
4		No	Go to the next step.
5	INSPECT SHIFT SOLENOID D CONNECTOR FOR POOR CONNECTION • Disconnect the shift solenoid F connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is the connection normal?	Yes	Go to the next step.
5		No	Repair or replace the connector and/or terminals, then go to Step 11.
6	INSPECT RESISTANCE • Inspect the resistance between shift solenoid F terminal A (part-side) and body ground. • Is the resistance within 10.9-26.2 ohms? (See Resistance Inspection (On-Vehicle Inspection).)	Yes	Replace the solenoid wiring harness, then go to Step 11.
6		No	Verify shift solenoid F installation. • If solenoid installed correctly, replace the solenoid, then go to Step 11. (See SOLENOID VALVE REMOVAL/INSTALLATION (SECONDARY CONTROL VALVE BODY) [FS5A-EL].)
7	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is the connection normal?	Yes	Go to the next step.
7		No	Repair or replace the connector and/or terminals, then go to Step 11.
8	INSPECT TRANSAXLE CONNECTOR CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between TCM terminal 1J (wiring harness-side) and transaxle connector (secondary) terminal B (wiring harness-side). • Is there continuity between terminals?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness, then go to Step 11.
9	INSPECT TRANSAXLE CONNECTOR CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Inspect the voltage at transaxle connector (secondary) terminal B (wiring harness-side). • Is the voltage 0 V?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness, then go to Step 11.
10	INSPECT TCM CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch to the LOCK position. • Inspect for continuity between TCM terminal 1J (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 11.
10		No	Go to the next step.
11	VERIFY TROUBLESHOOTING OF DTC P2709 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the WDS or equivalent. • Drive the vehicle in D range and make sure that gears shift smoothly from 1GR to 5GR. • Are any DTCs present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [FS5A-EL].)
11		No	No concern is detected. Go to the next step.
12	VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [FS5A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection.
12		No	DTC troubleshooting completed.
