Diagnostic procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE: Recording can be facilitated using the screen capture of the PC function. Record the freeze frame data/snap shot data.	—	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.
		No	Go to the next step.
3	INSPECT TCM CONNECTOR FOR POOR CONNECTION Switch the ignition off. Disconnect the TCM connector. Inspect for poor connection at TCM terminals 2Z and 2O (such as damaged/pulled-out pins, corrosion). Are terminals normal?	Yes	Go to the next step.
		No	Repair or replace the connector and/or terminal, then go to Step 13.
4	INSPECT RESISTANCE OF SHIFT SOLENOID F CIRCUIT Inspect for resistance between TCM terminals 2Z and 2O (wiring harness-side). Is the resistance within 5.0—5.6 ohms? (See SOLENOID VALVE INSPECTION [SJ6A-EL].)	Yes	Go to the next step.
		No	Go to go to Step 7.
5	INSPECT SHIFT SOLENOID F CIRCUIT FOR SHORT TO GROUND Disconnect the coupler component connector. Inspect for continuity between TCM terminals (wiring harness-side) and body ground. Terminal 2Z and body ground Terminal 2O and body ground Is there continuity?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: Shift solenoid F terminal B—TCM terminal 2Z Shift solenoid F terminal A—TCM terminal 2O If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to ground. Go to Step 13.
6	INSPECT SHIFT SOLENOID F CIRCUIT FOR SHORT TO GROUND Inspect for continuity between coupler component terminals (wiring harness-side) and body ground. Terminal F and body ground Terminal E and body ground Is there continuity?	Yes	Go to go to Step 13.
		No	Repair or replace the coupler component, then go to the next step.
7	INSPECT COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION Switch the ignition off. Disconnect the coupler component connector. Inspect for poor connection at coupler component terminals H and G (such as damaged/pulled-out pins, corrosion). Are terminals normal?	Yes	Go to the next step.
		No	Repair or replace the connector and/or terminal, then go to Step 13.
8	INSPECT RESISTANCE OF SHIFT SOLENOID F CIRCUIT Inspect the resistance between coupler component (transmission case side) terminals H and G. Is the resistance within 5.0—5.6 ohms? (See SOLENOID VALVE INSPECTION [SJ6A-EL].)	Yes	Go to the next step.
		No	Go to Step 10.
9	INSPECT SHIFT SOLENOID F CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between TCM terminals and coupler component terminals (wiring harness-side). Terminal 2Z and terminal F Terminal 2O and terminal E Is there continuity?	Yes	Go to Step 13.
		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: TCM terminal 2Z—Coupler component terminal F TCM terminal 2O—Coupler component terminal E If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 13.
10	INSPECT SHIFT SOLENOID F CONNECTOR FOR POOR CONNECTION Disconnect the shift solenoid F connector. Inspect for poor connection at shift solenoid F terminals A and B (such as damaged/pulled-out pins, corrosion). Are terminals normal?	Yes	Go to the next step.
		No	Repair or replace the connector and/or terminal, then go to Step 13.
11	INSPECT SHIFT SOLENOID F Inspect the shift solenoid F. (See SOLENOID VALVE INSPECTION [SJ6A-EL].) Is the shift solenoid F normal?	Yes	Go to the next step.
		No	Replace the control valve body, then go to Step 13. (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].) (See CONTROL VALVE BODY INSTALLATION [SJ6A-EL].)
12	INSPECT SHIFT SOLENOID F CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between coupler component terminals and shift solenoid F terminals (wiring harness-side). Terminal F and terminal B Terminal E and terminal A Is there continuity?	Yes	Go to the next step.
		No	Repair or replace the coupler component, then go to the next step.
13	VERIFY SAME DTC IS NOT PRESENT Always reconnect all disconnected connectors. Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) Perform the following procedure to ensure that the DTC has been resolved: Start the engine. Warm-up the engine and transmission. Drive the vehicle in D position and make sure that the gears shift smoothly from 1GR to 6GR. Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
		No	Go to the next step.
14	VERIFY DTC TROUBLESHOOTING COMPLETED Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (SJ6A-EL)].)
		No	DTC troubleshooting completed.
