2. Line pressure check
   CAUTION:

   • Wash the equipment and hoses with appropriate detergent before and after measurement.
   • Always perform the inspection after the engine check and adjustment.
   • Perform the inspection at an oil temperature (60 to 90°C) in normal driving condition.
   • Perform the inspection with the A/C OFF.
   • Do not perform the inspection continuously for 5 seconds or more at stall. (Time from the accelerator full close to full open, stall speed reading and the accelerator full close)
   • After performing the stall test, be sure to cool down the engine for at least 1 minute with the select lever set in P or N position, and at an idle speed of 1200 r/min or less.
   • If the stall speed is higher than the specified range, finish the stall test in as short a time as possible, in order to prevent the automatic transmission from being damaged.
   • Perform the stall test in normal mode.
   1. Remove the under cover No. 1.
   2. Remove the under cover No. 2.
   3. Remove the exhaust pipe ASSY FR.
   4. Attach the SST on the transmission.

      SST 18681AA040, 498897700, 498575400

      CAUTION:

      • Use 18681AA040 with genuine O-ring (17006AA000) attached.
      • Route the hose so that it does not contact the exhaust pipe.

   5. Install the center exhaust pipe.
   6. Firmly apply the parking brake and set the wheel stoppers.
   7. Remove the test plug, install the gauge and start the engine.
   8. Firmly depress the brake pedal with left foot and shift to D or R position, then check the hydraulic pressure at idling and stalling.
      STANDARD VALUE
      
      

      Shift position	While idling [MPa {kgf/cm2 }]	While stalling [MPa {kgf/cm2 }]
      D position	0.35 to 0.43 {3.6 to 4.4}	1.20 to 1.38 {12.2 to 14.0}
      R position	0.76 to 0.95 {7.7 to 9.7}	1.41 to 1.63 {14.4 to 16.6}

      NOTE: When there is an open or short circuit in the line pressure control solenoid ASSY (SLT) system, the line pressure reaches the maximum.

      NG: Repair or replacement of transmission valve body ASSY (refer to TRANSMISSION VALVE BODY ASSY )

      OK: Go to next step

3. Check of transmission 3 way solenoid ASSY (S4) system unit
   1. Remove the transmission 3 way solenoid ASSY (S4). (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  0)
   2. Check the transmission 3 way solenoid ASSY (S4) unit. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  6)

      NG: Replacement of the transmission 3 way solenoid ASSY (S4) (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  0)

      OK: Go to next step

4. Check of clutch control solenoid No. 1 (SL2) unit
   1. Check the clutch control solenoid No. 1 (SL2) unit. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  3)

      NG: Repair or replacement of transmission valve body ASSY (refer to TRANSMISSION VALVE BODY ASSY )

      OK: Go to next step

5. Check of transmission valve body ASSY unit
   1. Check the transmission valve body ASSY. (Refer to TRANSMISSION VALVE BODY ASSY )

      Criteria: There is no malfunction and foreign objects on the solenoid installation portions.

      NG: Repair or replacement of transmission valve body ASSY (refer to TRANSMISSION VALVE BODY ASSY )

      OK: Repair or replacement of automatic transmission ASSY (refer to REMOVAL )
