TEST MODE PROCEDURE
1. WARNING LIGHT AND INDICATOR LIGHT INITIAL CHECK
(a) Release the parking brake.
NOTICE:
Before releasing the parking brake, move the shift lever to P for safety.
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, brake warning, TRAC OFF indicator, VSC OFF indicator and slip indicator lights all come on for approximately 3 seconds.

2. SENSOR CHECK USING TEST MODE (SIGNAL CHECK) (When Using the Techstream)
HINT:
DTCs are stored if any malfunctions are detected during each sensor check.
(a) Procedure to enter Test Mode
(1) Turn the ignition switch off.
(2) Check that the steering wheel is centered.
(3) Check that the shift lever is in P.
(4) Connect the Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Turn the Techstream on.
(7) Switch the skid control ECU to Test Mode using the Techstream. Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Signal Check.
(8) Check that the ABS warning and slip indicator lights come on for several seconds and then blink in Test Mode.
HINT:
(9) Check the ABS sensors.
HINT:
Check that the ABS warning light is blinking in the Test Mode blinking pattern before performing the ABS sensor check.
(b) Lost Booster Pressure Judgement Check
NOTICE:
Perform the check in the lost booster pressure state (negative pressure in the booster is depressurized).
(1) Turn the ignition switch to ON.
(2) Check that the brake warning light comes on when depressing the brake pedal with a force of 65.5 N (6.7 kgf, 15.0 lbf) or more for 1 second or more. (The lost booster pressure state is judged to be normal.)
(3) Start the engine while depressing the brake pedal with a force of 65.5 N (6.7 kgf, 15.0 lbf) or more for 1 second or more.
(4) Check that the brake warning light goes off when quickly releasing the brake pedal. (The lost booster pressure state is judged to be normal.)
NOTICE:
HINT:
If the lost booster pressure state is not judged to be normal, the brake warning light comes on and Test Mode DTC C1281 (Master Cylinder Pressure Sensor Output Malfunction) is recorded.
(c) Speed Sensor Check
(1) Drive the vehicle straight-ahead.
Accelerate the vehicle to a speed of 45 km/h (28 mph) or more for several seconds.
(2) Check that the ABS warning light goes off.
HINT:
(3) Stop the vehicle.
NOTICE:
Decelerate or stop the vehicle before the speed reaches 80 km/h (50 mph).
HINT:
When the sensor check has been completed, the ABS warning light goes off while driving and blinks in the Test Mode pattern while stationary.
(d) VSC OFF Switch Check
(1) Check that the TRAC OFF indicator light comes on and VSC OFF indicator light goes off.
(2) Press the VSC OFF switch.
(3) Check that the TRAC OFF indicator light goes off.
(4) Press and hold the VSC OFF switch for 3 seconds or more.
(5) Check that the TRAC OFF indicator and VSC OFF indicator lights come on.
(e) End of Sensor Check
(1) 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 driving.
NOTICE:
If the sensor check has not been completed, the ABS warning light will blink while driving and the ABS system will not operate.
(f) Read Sensor Check DTCs
(1) Read the DTC(s) by following the Techstream screen.
NOTICE:
HINT:
See "Sensor Check DTCs".
(2) Turn the ignition switch off and disconnect the Techstream.

(a) Procedure to enter Test Mode
(1) Turn the ignition switch off.
(2) Check that the steering wheel is centered.
(3) Check that the shift lever is in P.
(4) Using SST, connect terminals TS and CG of the DLC3.
