Test Mode Procedure

BRAKE CONTROL: ANTI-LOCK BRAKE SYSTEM (for Hatchback): TEST MODE PROCEDURE

TEST MODE PROCEDURE

1. WARNING LIGHT AND INDICATOR LIGHT INITIAL CHECK

(a) Release the parking brake.
NOTE: Before releasing the parking brake, move the shift lever to P (for automatic transaxle model) or set chocks (for manual transaxle model) to prevent the vehicle from rolling.
HINT: When the parking brake is applied or the brake fluid level is low, the brake warning light comes on.

(b) When the ignition switch is turned to ON, check that the ABS warning and brake warning lights come on for approximately 3 seconds.
HINT:
- If the skid control ECU stores any DTCs, the ABS warning light will come on.
- If the indicator remains on or does not come on, proceed to troubleshooting for the light circuits listed below.

2. TEST MODE PROCEDURE (SIGNAL CHECK) (Using Techstream)
HINT:
- If the ignition switch is turned from ON to ACC or OFF during Test Mode (signal check), DTCs recorded during the signal check function will be cleared.
- During Test Mode (signal check), the skid control ECU records all DTCs of the signal check function. By performing the Test Mode (signal check), the codes are cleared if a normal condition is confirmed. The remaining codes are the codes where an abnormality was found.

(a) Procedure to enter Test Mode.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) for Automatic transaxle: Check that the shift lever is in P and apply the parking brake.
(4) for Manual transaxle: Check that the shift lever is in neutral and apply the parking brake.
(5) Connect the Techstream to the DLC3.
(6) Turn the ignition switch to ON.
(7) Turn the tester on.
(8) Enter the following menus: Chassis / ABS/VSC/TRC / Signal Check.

(9) 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 TS and CG terminal circuit and ABS warning light circuit.

3. SPEED SENSOR CHECK (Using Techstream)
(a) Check the speed sensor signal.
(1) Drive the vehicle straight-ahead.
Accelerate the vehicle to a speed of 45 km/h (28 mph) or more for several seconds and check that the ABS warning light goes off.

- The sensor check may not be completed if wheels pin occurs.
- The ABS warning light blinks when the sensor 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 check.

(b) Stop the vehicle.

NOTICE:
- The speed sensor check may not be completed if the speed sensor check is started while turning the steering wheel or spinning the wheels.
- After the ABS warning light goes off and if the vehicle speed exceeds 80 km/h (50 mph), a sensor check code will be stored again. Decelerate or stop the vehicle before the speed reaches 80 km/h (50 mph).
- If the sensor check has not been completed, the ABS warning light blinks during driving and the ABS system does not operate.
HINT: When the sensor check has been completed, the ABS warning light goes off during driving and blinks in the Test Mode pattern while the vehicle is stationary.

4. END OF SENSOR CHECK (Using Techstream)

(a) If the sensor check is completed, the ABS warning light blinks (Test Mode) when the vehicle stops and the ABS warning light is off while the vehicle is being driven.
NOTE: If the sensor check is not completed, the ABS warning light blinks even while the vehicle is being driven and the ABS does not operate.

5. READ DTC OF SIGNAL CHECK FUNCTION (Using Techstream)
(a) Read the DTC(s) by following the tester screen.
NOTICE:
- If only the DTCs are displayed, repair the malfunction area and clear the DTCs.
- If the DTCs or Test Mode codes (DTC of signal check function) are displayed, repair the malfunction area, clear the DTCs, and perform Test Mode inspection.
HINT: See the list of DTCs (See procedure "A").

6. TEST MODE PROCEDURE (SIGNAL CHECK) (Using SST Check Wire)
HINT:
- If the ignition switch is turned from ON to ACC or off during Test Mode (signal check), DTCs recorded during the signal check function will be cleared.
- During Test Mode (signal check), the skid control ECU records all DTCs of the signal check function. By performing the Test Mode (signal check), the codes are cleared if a normal condition is confirmed. The remaining codes are the codes where an abnormality was found.

(a) Procedure to enter Test Mode.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) for Automatic transaxle: Check that the shift lever is in P and apply the parking brake.
(4) for Manual transaxle: Check that the shift lever is in neutral and apply the parking brake.

(5) Using SST, connect terminals TS and CG of the DLC3.
SST: 09843-18040
(6) Turn the ignition switch to ON.

(7) 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 TS and CG terminal circuit and ABS warning light circuit.

7. SPEED SENSOR CHECK (Using SST Check Wire)
(a) Check the speed sensor signal.
(1) Drive the vehicle straight-ahead.
Accelerate the vehicle to a speed of 45 km/h (28 mph) or more for several seconds and check that the ABS warning light goes off.

- The sensor check may not be completed if wheels pin occurs.
- The ABS warning light blinks when the sensor 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 check.

(b) Stop the vehicle.

NOTICE:
- The speed sensor check may not be completed if the speed sensor check is started while turning the steering wheel or spinning the wheels.
- After the ABS warning light goes off, if vehicle speed exceeds 80 km/h (50 mph), a sensor check code will be stored again. Decelerate or stop the vehicle before the speed reaches 80 km/h (50 mph).
- If the sensor check has not been completed, the ABS warning light blinks during driving and the ABS system does not operate.
HINT: When the sensor check has been completed, the ABS warning light goes off during driving and blinks in the Test Mode pattern while the vehicle is stationary.

8. END OF SENSOR CHECK (for Using SST Check Wire)

(a) Using SST, connect terminals TC and CG of the DLC3.
SST: 09843-18040

(b) Count the number of blinks of the ABS warning light.

NOTICE:
- If only the DTCs are displayed, repair the malfunction area and clear the DTCs.
- If the DTCs or Test Mode codes (DTC of signal check function) are displayed, repair the malfunction area, clear the DTCs, and perform Test Mode inspection.
HINT:
- If more than 1 malfunction is detected at the same time, the lowest-numbered code will be displayed first.
- See the list of DTCs (See procedure "A").

(c) After performing the check, disconnect SST from terminals TS and CG, and TC and CG of the DLC3 and turn the ignition switch off.
(d) Turn the ignition switch to ON.
HINT:
- If the ignition switch is not turned to ON after SST is removed from the DLC3, the previous Test Mode will continue.
- If the ignition switch is turned to ON with terminals TS and CG shorted, the previous Test Mode will continue.
