Diagnostic procedure

STEP	INSPECTION		ACTION
1	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.
1		No	Go to the next step.
2	INSPECT ATF CONDITION • Inspect the ATF condition. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [FS5A-EL].) • Is it normal?	Yes	Go to the next step.
2		No	Replace the ATF, then go to Step 9. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [FS5A-EL].)
3	INSPECT ATF LEVEL • Inspect the ATF level. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [FS5A-EL].) • Is it normal?	Yes	Go to the next step.
3		No	Add ATF to the specified level, then go to Step 9. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [FS5A-EL].)
4	INSPECT SOLENOID VALVE • Inspect the following solenoid valves: (See SOLENOID VALVE INSPECTION (PRIMARY CONTROL VALVE BODY) [FS5A-EL].) ― Pressure control solenoid A ― Shift solenoid A ― Shift solenoid C • Is there any malfunction?	Yes	Replace the solenoid valve, then go to Step 9. (See SOLENOID VALVE REMOVAL/INSTALLATION (PRIMARY CONTROL VALVE BODY) [FS5A-EL].)
4		No	Go to the next step.
5	INSPECT LINE PRESSURE • Perform the “Line Pressures Test”. (See MECHANICAL SYSTEM TEST [FS5A-EL].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to test result, then go to Step 9.
5		No	Go to the next step.
6	INSPECT STALL SPEED • Perform the “Stall Test”. (See MECHANICAL SYSTEM TEST [FS5A-EL].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to test result, then go to Step 9.
6		No	Go to the next step.
7	INSPECT TURBINE SPEED WHILE DRIVING VEHICLE • Connect the M-MDS. • Start the engine. • Measure the PID “TSS” while driving vehicle under the following conditions: ― Selector lever position: D range ― Gear position: 3GR ― Vehicle speed: 60 km/h {37 mph} • Is the PID “TSS“ approx.2,542 RPM (MZR 2.0, MZR 2.5) / approx.2,510 RPM (MZR 2.0 DISI)?	Yes	Go to Step 9.
7		No	Go to the next step.
8	INSPECT PRIMARY CONTROL VALVE BODY • Remove the primary control valve body. (See PRIMARY CONTROL VALVE BODY REMOVAL [FS5A-EL].) • Disassemble the primary control valve body. • Inspect the following parts: ― Shift valve ― Return spring ― Hydraulic passage • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to inspection result, then go to next step.
8		No	Replace the transaxle, then go to the next step. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [FS5A-EL].)
9	VERIFY TROUBLESHOOTING OF DTC P0733:00 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. Drive the vehicle under the following conditions for 2 s or more. ― 3GR ― Vehicle speed: more than 25 km/h {16 mph} (MZR 2.0, MZR 2.0 DISI) / more than 26 km/h {17 mph} (MZR 2.5) ― TCC operation: Off 2. Drive the vehicle under the following conditions for 5 s or more. ― Accelerator pedal position: 0—6.25% ― Vehicle speed: more than 38 km/h {24 mph} • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [FS5A-EL].)
9		No	Go to the next step.
10	VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FS5A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FS5A-EL].)
10		No	DTC troubleshooting completed.
