The ABS control unit continuously monitors the speed of each wheel. If one wheel is about to lock up, the ABS responds by automatically releasing and reapplying that wheel's brake.
The driver will feel a slight vibration in the brake pedal and may hear a chattering noise from the brake system. This is normal ABS system operation. Continue to depress the brake pedal without pumping the brakes.
A system malfunction or operation conditions are indicated by a warning.
Refer to Warning/Indicator Lights on .
WARNING
Do not rely on ABS as a substitute for safe driving:
The ABS cannot compensate for unsafe and reckless driving, excessive speed, tailgating (following another vehicle too closely), driving on ice and snow, and hydroplaning (reduced tire friction and road contact because of water on the road surface). You can still have an accident.
NOTE
•Braking distances may be longer on loose surfaces (snow or gravel, for example) which usually have a hard foundation. A vehicle with a normal braking system may require less distance to stop under these conditions because the tires will build up a wedge of surface layer when the wheels skid.
•The sound of the ABS operating may be heard when starting the engine or immediately after starting the vehicle, however, it does not indicate a malfunction.

Traction Control System (TCS)Engine Oil Control
Outline
The PCM reduces the oil pump load applied to the engine by controlling the
appropriate engine hydraulic pressure according to the engine operation conditions.
The engine hydraulic pressure switches in two steps. When hydraulic pressure
is not needed, the oil pump dischar ...
Magnetic Clutch Adjustment [Full Auto Air Conditioner]
1. Measure the clearance around the entire circumference between the pressure
plate and A/C compressor pulley using a thickness gauge.
2. Verify the clearance.
If not within the specification, remove the pressure plate and adjust the
clearance by changing the shim (0.2 mm {0.008 i ...
Fuel Injection Control System
Outline
Performs optimum fuel injection according to engine operation conditions.
The PCM determines the engine operation conditions based on the signals from
each input device and drives the fuel injectors at the optimal fuel injection
time (fuel injection amount) and the fuel ...
