Outline of Laser Beam Aiming Adjustment ProcedureEKS007TI
CAUTION:
The laser beam aiming adjustment cannot be performed without CONSULT-II.
The laser beam aiming adjustment must be performed every time the ICC sensor is removed,
installed or has been moved as a result of a collision.
1. Prepare the vehicle and the work area.
2. Set up the ICC target board.
3. Adjust the sensor following the procedure on CONSULT-II.
4. Check system operation after the adjustment.
PreparationEKS007PC
Place the vehicle on level ground. Shift the transmission into "P" position and release the parking brake.
Adjust the tire pressure to the specified value.
See that there is no load in the vehicle. Coolant, engine oil and fuel should be filled to correct level.
Check that the vehicle suspension has been adjusted to the standard height by the load leveling rear air
suspension system. Refer to RSU-12, "
Basic Inspection" .
Clean the ICC sensor with a soft cloth.
Setting up the ICC Target BoardEKS007PE
CAUTION:
Accuracy in setting up the ICC target board is essential for the laser beam aiming adjustment.
ADJUSTING HEIGHT OF THE ICC TARGET BOARD
1. Attach a triangle scale as shown.Tool number : KV99110100 (J-45718)

The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.
HFC-134a (R-134a) Service Tools and EquipmentEJS002BQ
Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubri-
cant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used refrigerant/lubricant contamination will
occur and compressor failure will result.
