TEST MODE PROCEDURE
1. TEST MODE PROCEDURE (for Using Techstream)
HINT:
(a) Turn the ignition switch to off.
(b) Check that the steering wheel is in the straight-ahead position.
(c) for Automatic Transmission:
Check that the shift lever is in P and apply the parking brake.
(d) for Manual Transmission:
Check that the shift lever is in neutral and apply the parking brake.
(e) Connect Techstream to the DLC3.
(f) Turn the ignition switch to ON.
(g) Switch the ECU to test mode using Techstream. Enter the following menu items: Chassis / ABS/VSC/TRAC / Utility / Signal Check.
(h) Check that the ABS warning light and slip indicator light blink at 0.125 second intervals (0.125 seconds on and 0.125 seconds off).
HINT:
If the ABS warning light and slip indicator light do not blink the ABS warning light circuit and slip indicator light circuit.

(i) Start the engine.
2. ACCELERATION SENSOR SIGNAL CHECK
(a) Keep the vehicle stationary on a level surface for 1 second or more.
HINT:
Acceleration sensor check can be performed with the master cylinder pressure sensor check below.
3. MASTER CYLINDER PRESSURE SENSOR CHECK
(a) Keep the vehicle stationary and release the brake pedal for 1 second or more, and quickly depress the brake pedal with a force of 98 N (10 kgf) or more for 1 second or more.
4. 4WD DETECTION SWITCH SIGNAL CHECK
(a) Check the 4WD detection switch (4WD position).
(1) Push and turn the 4 wheel drive control switch to put the vehicle in 4WD mode.
(2) Push and turn the 4 wheel drive control switch to put the vehicle in 2WD mode.
5. SPEED SENSOR CHECK
(a) Check the speed sensor signal
(1) Drive the vehicle straight forward at a speed of 45 km/h (28 mph) or more for several seconds.
(2) Check that the ABS warning light goes off.
(3) Drive the vehicle in reverse for more than 1 second at 3 km/h (2 mph) or more.
HINT:
Drive the vehicle in reverse and check the speed sensor signal. Note that the signal check cannot be completed if the vehicle speed is 45 km/h (28 mph) or more.
(4) Check that the ABS warning light goes off.
HINT:
(5) Stop the vehicle.
NOTICE:
HINT:
When the signal check has been completed, the ABS warning light goes off while driving and blinks in test mode while stationary.
6. END OF ABS SENSOR CHECK
(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 driving.
NOTICE:
7. READ DTC OF ABS SENSOR (for Using Techstream)
(a) Read the DTC(s) by following the Techstream screen.
HINT:
Refer to Techstream operator's manual for further details.
8. MTS SET SWITCH SIGNAL CHECK (for Automatic transmission)
(a) Turn the 4 wheel drive control switch to the L position to put the vehicle in L4 mode.
(b) Press the MTS SET switch.
(c) Check that the MTS SET indicator light comes on.
(d) Press the MTS SET switch again to turn the MTS SET indicator light off.
HINT:
Move the vehicle either a little forward or a little backward to engage the L4 position.
9. CRAWL SWITCH CHECK (for Automatic transmission)
(a) Push the ON/OFF switch.
HINT:
The CRAWL indicator light illuminates while the ON/OFF switch is pushed.

10. VSC OFF SWITCH CHECK
(a) Press the VSC OFF switch.
(b) Check that the AUTO LSD indicator light and VSC OFF indicator light come on.
(c) Press the VSC OFF switch again to turn the AUTO LSD indicator light and VSC OFF indicator light off.
11. END OF VSC SENSOR CHECK
(a) If the sensor check is completed, the slip indicator light blinks (Test Mode).
NOTICE:
If the sensor check is not completed, the slip indicator light blinks even while the vehicle is driving and the VSC and traction control function do not operate.
12. READ DTC OF VSC SENSOR (for Using Techstream)
(a) Read the DTC(s) by following the Techstream screen.
