Displaying & Reading Trouble Codes

NOTE: This is the only information provided by the manufacturer for Reading Diagnostic Trouble Codes for this system.

PRE-CHECK

1. DIAGNOSIS SYSTEM




a. Check the indicator.
When the ignition switch is turned ON, check that the ABS warning light goes on for 3 seconds.

HINT: If the indicator check result is not normal, proceed to troubleshooting for the ABS warning light circuit.

b. Check the DTC.




1. Using SST, connect terminals Tc and CG of the DLC3.
SST 09843-18040

2. Turn the ignition switch ON.
3. Read the DTC from the ABS warning light on the combination meter.

NOTE: Pay due attention to the terminal connecting position to avoid a malfunction.






HINT:
- If no code appears, inspect the ABS warning light circuit or diagnostic circuit.
- As an example, the blinking patterns for normal code and codes 11 and 21 are shown.

4. Codes are explained in Trouble Code Descriptions.
5. After completing the check, disconnect terminals Tc and CG of the DLC3, and turn off the display.

If 2 or more malfunctions are indicated at the same time the lowest numbered DTC will be displayed 1st.




c. Clear the DTC.

1. Using SST, connect terminals Tc and CG of the DLC3.
SST 09843-18040

2. Turn the ignition switch ON.
3. Clear the DTC stored in ECU by depressing the brake pedal 8 or more times within 5 seconds.
4. Check that the warning light shows the normal code.
5. Remove the SST from the terminals of DLC3.
SST 09843-18040

HINT: Cancellation cannot be done by removing the battery cable or ECU-IG fuse.

2. SPEED SENSOR SIGNAL CHECK (TEST MODE)

a. Check the sensor signal.




1. Turn the ignition switch OFF.
2. Using SST, connect terminals Ts and CG of the DLC3.
SST 09843-18040

3. Start the engine.

NOTE: Pay due attention to the terminal connecting position to avoid a malfunction.




4. Check that the ABS warning light blinks.

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

5. Drive vehicle straight forward.
Drive vehicle at a speed faster than 45 km/h (28 mph) for several seconds and check that the ABS warning light comes off.

HINT: The sensor check may not be completed if the front wheels are spun or the steering wheel is steered during this check.

6. Stop the vehicle.

7. Using SST, connect terminals Ts and CG of the DLC3.
SST 09843-18040

8. Turn the ignition switch ON.
9. 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 malfunction codes are identified at the same time, the lowest numbered code will be displayed 1st.

10. After doing the check, disconnect the SST from terminals of the DLC3, and turn the ignition switch OFF.

71 - 79:

DTC of speed sensor check function

3. 4WD:
DECELERATION SENSOR CHECK

a. Check the deceleration sensor detection point.




1. Turn the ignition switch OFF.

2. Using SST, connect terminals Ts and CG of the 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.




5. Jack up the rear side of the vehicle slowly, as shown.

HINT: When measuring the height, measure at the center of the lower body of the vehicle.

6. Check that the ABS warning light blinks.
If the warning light turns on, inspect the deceleration sensor installation. If the sensor installation is OK, replace the deceleration sensor.




7. Jack down the vehicle slowly.

8. Jack up the front side of the vehicle slowly, as shown.

HINT: When measuring the height, measure at the center of the lower body of the vehicle.

9. Check that the ABS warning light blinks.
If the warning light turns on, inspect the deceleration sensor installation. If the sensor installation is OK, replace the deceleration sensor.

10. Jack down the vehicle slowly.

b. Check the deceleration sensor operation.




1. Drive the vehicle straight ahead at about 20 km/h (12.4 mph) or more, lightly depress the brake pedal.

2. Check that there is no change in the warning light pattern.




3. Drive the vehicle straight ahead at about 20 km/h (12.4 mph) or more, and depress the brake pedal moderately.

4. Check that the warning light turns on while braking.




5. Drive the vehicle straight ahead at about 20 km/h (12.4 mph) or more, and depress the brake pedal strongly

6. Check that the warning light pattern changes while braking, as shown.

If the operation is not as specified, inspect the deceleration sensor installation. If the sensor installation is OK, replace the deceleration sensor.

7. Stop the vehicle and turn the ignition switch OFF.

8. Remove SST from the terminals Ts and CG of the DLC3.
