  1. Clean the mating surface of valve cover and transmission side. CAUTION: When cleaning the mating surface of the transmission side, be careful not to allow any dust, foreign matter and used liquid gasket to enter the transmission.
  2. Check the control valve body for dust and other foreign matter.
  3. Install the O-ring to the transmission harness. NOTE: Use new O-rings. Apply CVTF to the O-ring.
  4. Install the transmission harness to the valve cover. Tightening torque: 7 N.m (0.7 kgf-m, 5.2 ft-lb)
  5. Install the gasket to the transmission. NOTE: Use a new gasket.
  6. Apply liquid gasket to the oval hole of gasket. Liquid gasket: THREE BOND 1215 (Part No. 004403007) or equivalent
  7. Connect the transmission harness connector to the control valve body, and install the valve cover. CAUTION: Be careful not to catch the sheet of the ST. Tightening torque: 8 N.m (0.8 kgf-m, 5.9 ft-lb)
  8. Remove the ST (SHEET SPECIAL TOOL).
  9. Install the transmission harness connector to the harness stay.
  10. Install the transmission harness stay and transmission ground terminal. NOTE: Install the transmission ground terminal in the direction within the range of approx. 30° (A). Tightening torque: T1: 7 N.m (0.7 kgf-m, 5.2 ft-lb) T2: 14 N.m (1.4 kgf-m, 10.3 ft-lb)
  11. Install the transmission case cover. Tightening torque: 8 N.m (0.8 kgf-m, 5.9 ft-lb)
  12. Install the pitching stopper bracket and transmission radio ground cord. Tightening torque: 41 N.m (4.2 kgf-m, 30.2 ft-lb)
  13. Install the air breather hose to the pitching stopper bracket.
  14. Install the pitching stopper. Tightening torque: T1: 50 N.m (5.1 kgf-m, 36.9 ft-lb) T2: 58 N.m (5.9 kgf-m, 42.8 ft-lb)
  15. Connect the following harness connectors. Transmission harness connectors Inhibitor harness connector Transmission radio ground terminal Tightening torque: 13 N.m (1.3 kgf-m, 9.6 ft-lb)
  16. Install the air intake boot assembly. < Ref. to «INSTALLATION»(ref-662120-S17609314842014101300000) , Air Intake Boot. >
  17. Adjust the CVTF level. < Ref. to «ADJUSTMENT»(ref-662125-S03981071882014101300000) , CVTF. >

StepCheckYesNo
1 CHECK X MODE SWITCH. Turn the ignition switch to OFF. Disconnect the connector from body integrated unit. Measure the resistance when the X mode switch is operated. Connector & terminal (B281) No. 14 - Chassis groundDoes the resistance change as below? 1 Mohms or more --> less than 10 ohmsGo to step 5 .Go to step 2 .
2 CHECK HARNESS BETWEEN BODY INTEGRATED UNIT AND X MODE SWITCH CONNECTOR. Measure the resistance of harness between the body integrated unit connector and X mode switch connector. Connector & terminal (B281) No. 14 - (B185) No. 4Is the resistance less than 10 ohms?Go to step 3 .Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit of harness between the body integrated unit connector and X mode switch connector Poor contact of connector
3 CHECK HARNESS BETWEEN BODY INTEGRATED UNIT AND X MODE SWITCH CONNECTOR. Measure the resistance of harness between X mode switch connector and chassis ground. Connector & terminal (B185) No. 4 - Chassis groundIs the resistance 1 Mohms or more?Go to step 4 .Repair the ground short circuit of harness between body integrated unit and X mode switch connector.
4 CHECK HARNESS BETWEEN X MODE SWITCH CONNECTOR AND CHASSIS GROUND. Measure the resistance between body integrated unit connector and chassis ground. Connector & terminal (B185) No. 5 - Chassis groundIs the resistance less than 10 ohms?Repair the poor contact of X mode switch connector. Replace the X mode switch if faulty. < Ref. to X MODE SWITCH . > < Ref. to X MODE SWITCH . >Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between X mode switch connector and chassis ground Poor contact of joint connector
5 RECHECK FAULT. Connect all connectors. Switch to X mode.Is there any fault?Repair poor contact in the body integrated unit connector. Replace the meter case assembly if defective.The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
NOTE
In this case, repair the following item: Open circuit of harness between the body integrated unit connector and X mode switch connector Poor contact of connector
NOTE
In this case, repair the following item: Open circuit in harness between X mode switch connector and chassis ground Poor contact of joint connector
NOTE
In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
