Sensor Signal Check (Test Mode) (Using SST Check Wire)

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

If the ignition switch is turned from the ON to the ACC or LOCK position during test mode, DTCs of the sensor check function will be erased.







a. Procedures for sensor signal check
1. Turn the ignition switch off.
2. Check that the shift lever is in the P position.
3. Using SST, connect terminals TS and CG of the DLC3.

b. Start the sensor signal check.
1. Drive vehicle straight forward. Drive the vehicle at a speed of 34 mph (55 km/h) or higher for several seconds and check that the ABS warning light goes off.

NOTE:
- The speed sensor check may not be completed if it is started while turning the steering wheel or spinning the wheels.
- If sensor check has not been completed, the ABS warning light blinks while driving and the ABS system does not operate.

2. Stop the vehicle.




c. Read the DTCs
1. Using SST, connect terminals TC and CG of the DLC3.

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

HINT:
- See the list of DTC (Refer to step 4).
- 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 2 or more malfunctions are indicated at the same time, the lowest numbered code will be displayed 1st.




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