Wheel Speed and Modulator Control

When the wheel speed drops sharply below the vehicle speed, the inlet valve closes to retain the caliper fluid pressure.

When the wheel speed drops further, the outlet valve opens momentarily to reduce the caliper fluid pressure. The pump

motor starts at this time.

As the wheel speed is restored, the inlet valve opens momentarily to increase the caliper fluid pressure.

Wheel Sensor

The wheel sensors are the magnetic contactless type.

As the gear pulser teeth rotate past the wheel sensor's magnetic coil, AC current is generated. The AC frequency changes

in accordance with the wheel speed. The ABS control unit detects the wheel sensor signal frequency and thereby detects

the wheel speed.

There are four wheel sensors, one for each wheel.

The gear pulser has 50 teeth.

DISCHARGE LINE

This vehicle uses HFC-134a (R-134a) refrigerant which does not contain chlorofluorocarbons. Pay attention to the follow-

ing service items:

Do not mix refrigerants CFC-12 (R-12) and HFC-134a (R-134a). They are not compatible.

Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (ND-OIL 8) designed for the R-134a compressor.

Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil will result in compressor failure.

All A/C system parts (compressor, discharge line, suction line, evaporator, condenser, receiver/dryer, expansion valve.

O-rings for joints) have to be proper for refrigerant R-134a. Do not confuse with R-12 parts.

Use a halogen gas leak detector designed for refrigerant R-134a.

R-12 and R-134a refrigerant servicing equipment are not interchangeable. Use only a Recovery/Recycling/Charging System

that is U.L.-listed and is certified to meet the requirements of SAE J2210 to service R-134a air conditioning systems.

Always recover the refrigerant R-134a with an approved Recovery/Recycling/Charging System before disconnecting

any A/C fitting.
