Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed. • *1:

(a) Drive the vehicle at 12 mph (20 km/h) for 30 seconds or more and check that the ABS warning light goes off.

(a)Keep the vehicle in the stationary condition for 5 seconds or more and depress the brake pedal lightly 2 or 3 times.

(b)Drive the vehicle at the vehicle speed of 31 mph (50 km/h) and keep depressing the brake pedal strongly for approximately 3 seconds.

(c) Repeat the above operation 3 times or more and check that the ABS warning light goes off.

In some cases, the intelligent tester cannot be used when the ABS warning light remains on.

DESCRIPTION

The speed sensor detects wheel speed and transmits the appropriate signals to the skid control ECU. These signals are used for control of the ABS system. Each of the front and rear rotors has 48 serrations. When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces AC voltage. Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the skid control ECU to detect the speed of each wheel. DTCs C1271/71, C1272/72, C1275/75 and C1276/76 are output only in the test mode (SIGNAL CHECK).
