Test Mode Procedure

TEST MODE PROCEDURE

SPEED SENSOR SIGNAL CHECK (TEST MODE) (USING HAND-HELD TESTER)

HINT:
- If the ignition switch is turned from on (IG) to off during test mode (SIGNAL CHECK), the DTCs of the sensor check function will be erased.
- During test mode (SIGNAL CHECK), the skid control ECU records DTCs, if the abnormal sensor signal is received.

a. Procedures for test mode:
1. Turn the ignition switch off.
2. Move the shift lever to the P position.




3. Connect the hand-held tester to the DLC3.
4. Turn the ignition switch on (IG).




5. Select "SIGNAL CHECK" on the hand-held tester screen.

HINT: Refer to the hand-held tester operator's manual for further details.




6. Check that the ABS warning light comes on for several seconds and then blinks in test mode.

HINT: If the ABS warning light does not blink, inspect the ABS warning light circuit.
Trouble area
ABS warning light circuit (Remains on)
ABS warning light (Does not come on)

7. Start the engine.

b. Check the speed sensor signal.
1. Drive the vehicle straight forward.
Accelerate the vehicle to a speed of 34 mph (55 km/h) or more.
2. Depress the brake pedal 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.
- The ABS warning light goes off when the sensor signal check has been completed and the brake pedal is depressed.
- The ABS warning light comes on immediately after a malfunction has been detected during the speed sensor signal check.

3. Stop the vehicle.
4. Read the DTCs by following the tester screen.

HINT: See the list of DTCs shown in step 3.

SPEED SENSOR SIGNAL CHECK (TEST MODE) (USING SST CHECK WIRE)

HINT:
- If the ignition switch is turned from on (IG) to off during test mode, the DTCs of the sensor signal check function will be erased.
- During test mode (SIGNAL CHECK), the skid control ECU records DTCs, if the abnormal sensor is received.

a. Procedures for test mode:
1. Turn the ignition switch off.
2. Move the shift lever to the P position.




3. Using SST, connect terminals TS and CG of the DLC3.

SST 09843-18040

4. Turn the ignition switch on (IG).




5. Check that the ABS warning light comes on for several seconds and then blinks in test mode.

HINT: If the ABS warning light does not blink, inspect the ABS warning light circuit and TS terminal circuit.

Trouble area
ABS warning light circuit (Remains on)
ABS warning light circuit (Does not come on)
TS and CG terminal circuit

6. Start the engine.

b. Check the speed sensor signal:
1. Drive the vehicle straight forward.
Accelerate the vehicle to a speed of 34 mph (55 km/h) or more.

2. Depress the brake pedal and check that the ABS warning light goes off.

HINT:
- The sensor check may not be completed if the vehicle has its wheels spun or its steering wheel turned during this check.
- The ABS warning light goes off when the sensor signal check has been completed and the brake pedal is depressed.
- The ABS warning light comes on immediately after a malfunction has been detected during the speed sensor signal check.

3. Stop the vehicle.




4. Using SST, connect terminals TC and CG of the DLC3.

SST 09843-18040

5. Read the number of blinks of the ABS warning light.




HINT:
- See the list of DTCs shown in step 3.
- If every sensor is normal, a normal code will be output (A cycle of 0.25 second ON and 0.25 second OFF is repeated).
- If 2 or more malfunctions are indicated at the same time, the lowest numbered code will be displayed first.

6. After performing the check, turn the ignition switch off, and remove the SST from the DLC3.

SST 09843-18040

7. Turn the ignition switch on (IG).

HINT: If the ignition switch is not turned to the ON position after the SST is removed from the DLC3, the previous TEST MODE will continue.
