SUSPENSION CONTROL SYSTEM ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK FLUID LEVEL IN RESERVOIR

   
   

   1. 

      With the vehicle empty, after setting the vehicle height to NORMAL from LO, check the indicator to make sure the vehicle height is NORMAL and check that the fluid level in the reservoir tank is within the specified range (MAX, MIN).

      Tech Tips

      After changing the vehicle height from LO to NORMAL, do not stop the engine for 25 seconds because the pressure control for the main accumulator is operating. After that, check the fluid level.

2. INSPECT FOR SUSPENSION FLUID LEAK

   
   

   1. Check the torque value of the rear No. 5 height control tube union nuts.

      Torque:

      without union nut wrench

      15 N*m  { 155 kgf*cm, 11 ft.*lbf }

      with union nut wrench

      14 N*m  { 143 kgf*cm, 10 ft.*lbf }

      Tech Tips

      
      

      • Use a torque wrench with a fulcrum length of 300 mm (11.8 in.).

      • The torque value for use with a union nut wrench is effective when the union nut wrench is parallel to the torque wrench.

   2. Check for fluid leakage from the parts and connections.
