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

When the wheel speed drops sharply below the vehicle speed, the outlet valve opens momentarily to reduce the caliper

This vehicle uses HFC-I34a (R-l34a) refrigerant which does not contain chlorofluorocarbons. Pay attention to the follow-ing service items:
. Do not mix refrigerants CFC-12 (R-12) and HFC-l34a (R-134a). They are not compatible.. Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (SP-10) designed for the R-134a compressor.Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil will result in compressor failure.. Afl Ay'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 stationthat is U.L.iisted and is certified to meet the requirements of SAE J2210 to service R-134a air conditioning system.. Always recover the refrigerant R-134a with an approved recovery/recycling/charging station before disconnecting anylVC fitting.

A/C Service Tips and Precautions
The air conditioner system uses HFC-'134a (R-134a) refrigerant and polyalkyleneglycol {PAG) refrigerant oil*, which are not
compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do
not attempt to use R-12 servicing equipmenu damage to the air conditioner system or your servicing equipment will
resutr.
*KEIHIN SP-10:
. P/N 38897 - Pl3 - A01AH: 120 m{ (4 fl.oz, il.2 lmp.oz)
. P/N 38899 - Pl3 - A01: 40 mf 11113tl.oz,1.4 lmp.oz)
Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a
from the air conditioner system,
CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or misl can irritats eyes, nose and throat. Avoid
breathing the air conditioner refrigerant and lubricant vapor or mist,
lf accidental system discharge occurs, ventilate work area before resuming service.
R 134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed
air.
E@ Some mixtures of air and R-13,1a have been shown to be combustible at elevat€d pressures and can result
in fire or explosion causing iniury or property damage. Never use complessed air to pressure test R-l3,[a service equip-
ment or vehicle air conditioner systems.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
1. Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
2. Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't
remove the caps or plugs until just before you reconnect each line.
3. Before connecting any hose or line. apply a few drops of refrigerant oilto the O-ring,
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When discharging the system, use a R l34a refrigerant recovery/recycling/charging station; don't release refrigerant
into the atmosphere.
6. Add refrigerant oil after replacing the following parts.
Note these items when handling refrigerant oil:
o To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriger-
ant oils.
. lmmediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
. Do not spill the refrigerant oil on the vehicle; it may damage the painu if the refrigerant oil contacts the paint, wash
it off immediately.
