Component Tests
SPEED SENSOR SIGNAL CHECKHINT:
- If the ignition switch is turned from ON to ACC or LOCK during test mode, DTC of sensor check function will be erased.
- During test mode, ECU records all DTC of sensor check function. By performing sensor signal check, the codes are erased if normality is confirmed. The codes left over are the codes where abnormality was found.
a. In case of not using hand-held tester:
Check the speed sensor signal.
1. Turn the ignition switch ON.
2. Using SST connect the terminals Ts and CG of DLC3.
SST 09843-18040
3. Start the engine.
4. Check that the ABS warning light blinks.
HINT: If the ABS warning light does not blink, inspect the ABS warning light circuit and Ts circuit.
5. Drive the vehicle straight forward.
HINT: Drive the vehicle faster than 45 km/h (28 mph) for several sec.
6. Stop the vehicle.
7. Using SST, connect the terminals Tc and CG of the DLC3.
SST 09843-18040
8. Read the number of blinks of the ABS warning light.
HINT:
- See the list of DTC shown.
- If every sensor is normal, a normal code is 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.
9. After doing the check, turn the ignition switch OFF, and remove the SST from the DLC3.

b. In case of using hand-held tester:
Check the sensor signal.
1. Do step (3) to (6).
2. Read the DTC by following the prompts on the tester screen.
HINT: Please refer to the hand-held tester operator's manual for further details.
