Symptom 4: ABS Function Does Not OperateEFS005UB
CAUTION:
ABS does not operate when speed is 10 km/h (6 MPH) or lower.
1.CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
OK or NG
OK >> GO TO procedure 3 “CHECK WHEEL SENSOR AND SENSOR ROTOR” of symptom1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
NG >> Perform self-diagnosis. Refer toBRC-18, "
Self-Diagnosis".
Symptom 5: Pedal Vibration or ABS Operation Sound OccursEFS005UC
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
lWhen shifting gears
lWhen driving on slippery road
lDuring cornering at high speed
lWhen passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
lWhen pulling away just after starting engine [at approximately 10 km/h (6 MPH) or more]
1.SYMPTOM CHECK 1
Check if there is pedal vibration or operation noise when the engine is started.
Do symptoms occur?
YES >> GO TO 2.
NO >> Perform self-diagnosis. Refer toBRC-18, "
Self-Diagnosis".
2.SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO procedure 3²CHECK WHEEL SENSOR AND SENSOR ROTOR²of symptom 1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
Symptom 6: ABS Warning Lamp Indication Is Not NormalEFS005UD
NOTE:
Lighting condition of ABS warning lamp refer toBRC-24, "
BASIC INSPECTION 3 ABS WARNING LAMP AND
BRAKE WARNING LAMP INSPECTION".
1.CHECK COMBINATION METER INDICATION
Check the combination meter indication and operation. Refer toDI-13, "
Self-Diagnosis Mode of Combination
Meter".
OK or NG
OK >> GO TO 2.
NG >> Combination meter is malfunctioning. Check combination meter. Refer toDI-4, "
COMBINATION
METERS".

Fuel Injection Control SystemEBS01KCE
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.
