TEST MODE (SENSOR SIGNAL CHECK)Yaw rate sensor, deceleration sensor, master cylinder sensor and speed sensor, checks can be performed.
PROCEDURES FOR SENSOR SIGNAL CHECK (USING SST CHECK WIRE)
a. Turn the ignition switch off.
b. Using SST, connect terminals TS and CG of the DLC3.
SST 09843-18040
c. Check that the steering wheel is in the straight-ahead position and move the shift lever to the P position.
d. Turn the ignition switch to the ON position.
e. Check that the ABS warning light and VSC warning light blink as shown in illustration.
HINT: If the ABS warning light and VSC warning light do not blink, inspect the ABS warning light circuit and VSC warning light circuit.
Trouble area
ABS warning light circuit
VSC warning light circuit
f. Start the engine.
DECELERATION SENSOR CHECK (USING SST CHECK WIRE)
a. Check that the ABS warning light is blinking in TEST MODE.
b. Keep the vehicle in the stationary condition on a level surface for 1 second or more.
MASTER CYLINDER PRESSURE SENSOR CHECK (USING SST CHECK WIRE)
a. Check that the ABS warning light is blinking in TEST MODE.
b. Leave the vehicle in a stationary condition and the brake pedal in free condition for 1 second or more, and quickly depress the brake pedal with a force of 98 N (10 kgf, 22 lbf) or more for 1 second or more.
HINT: At this time, the ABS warning light comes on for 3 seconds.
SPEED SENSOR CHECK (USING SST CHECK WIRE)
a. Check the ABS warning light is blinking of TEST MODE.
b. Start the sensor signal check.
1. Drive the vehicle straight forward.
Drive the vehicle at a speed of 28 mph (45 km/h) or higher for several seconds and check that the ABS warning light goes off.
HINT: The sensor check may not be completed if the vehicle has its wheel spun or its steering wheel turned during this check.
2. Stop the vehicle.
c. Signal check results.
d. Read the DTCs
1. Using SST, connect terminals TC and CG of the DLC3.
SST 09843-18040
2. Read the number of blinks of the ABS warning light.
HINT:
- See the list of DTC (Refer to step 13).
- If every sensor is normal, the normal code is output (A cycle of 0.25 second ON and 0.25 second OFF is repeated).
- If more than 1 malfunction is detected at the same time, the lowest numbered code will be displayed first.
3. After the check, disconnect the SST from terminal TC and CG of the DLC3.
YAW RATE SENSOR CHECK (USING SST CHECK WIRE)
a. Check the VSC warning lamp is blinking of TEST MODE.
b. Shift the shift lever to the D range and drive the vehicle at the vehicle speed of approx. 3 mph (5 km/h), turn the steering wheel either to left or right 90 ° or more, and maintain 180 ° circular drive for the vehicle.
c. Stop the vehicle and shift the shift lever to the P position, check that the skid control buzzer sounds for 3 sec.
HINT:
- If the skid control buzzer sounds, the sensor check is completed normally.
- If the skid control buzzer does not sound, check the skid control buzzer circuit, then perform the sensor check again.
- If the skid control buzzer still won't sound, there is a malfunction in the VSC sensor, so check the DTC.
- Drive the vehicle in a 180 ° circle. At the end of the turn, the direction of the vehicle should be within 180 ° ≤ 5 ° of its start position.
- Do not spin the wheels.
d. Using SST, connect terminals TC and CG of DLC3.
SST 09843-18040
e. Read the number of blinks of the VSC warning light.
HINT:
- See the list of DTC.
- If every sensor is normal, there is a normal code output. (A cycle of 0.25 sec. ON and 0.25 sec. OFF is repeated.)
- If 2 or more malfunctions are indicated at the same time, the lowest numbered code will be displayed 1st.
f. After performing the check, disconnect the SST from terminals TS and CG, TC and CG of DLC3 and turn the ignition switch OFF.
