Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded on the repair order?	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 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 FOR ATF LEAKAGE • Verify that there is no ATF leaking from the transaxle case, and the connecting surfaces of the transaxle and the engine. • Is any ATF leakage verified?	Yes	After repairing the spot where there is ATF leakage, adjust the ATF level, then go to Step 8. (See AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT [AY6A-EL, AY6AX-EL].)
3		No	Go to the next step.
4	INSPECT ATF CONDITION • Inspect the ATF condition. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [AY6A-EL, AY6AX-EL].) • Is it normal?	Yes	Go to the next step.
4		No	Replace the ATF, then go to Step 8. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [AY6A-EL, AY6AX-EL].)
5	INSPECT LINE PRESSURE • Perform the “Line Pressures Test”. (See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to test result, then go to Step 8.
5		No	Go to the next step.
6	INSPECT STALL SPEED • Perform the “Stall Test”. (See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to test result, then go to Step 8.
6		No	Go to the next step.
7	INSPECT SOLENOID VALVE • Inspect the following solenoid valves: ― Shift solenoid A (See SHIFT SOLENOID A INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid B (See SHIFT SOLENOID B INSPECTION [AY6A-EL, AY6AX-EL].) ― Shift solenoid E (See SHIFT SOLENOID E INSPECTION [AY6A-EL, AY6AX-EL].) • Is there any malfunction?	Yes	Replace malfunctioning part according to test result, then go to the next step.
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Warm up the engine and transaxle. 3. Drive the vehicle in R position. • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
8		No	Go to the next step.
9	VERIFY NO DTCs ARE PRESENT • Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [AY6A-EL, AY6AX-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [AY6A-EL, AY6AX-EL].)
9		No	DTC troubleshooting completed.
