Test Mode Procedure [06/2016 - ]

WARNING LIGHT AND INDICATOR LIGHT INITIAL CHECK

Release the parking brake.
NOTE:
Before releasing the parking brake, move the shift lever to P (for automatic transmission) or set chocks 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.

When the ignition switch is turned to ON, check that the ABS warning, brake warning, TR(A)C OFF indicator, VSC OFF indicator, TRACK indicator and slip indicator lights all come on.

HINT:

If the skid control ECU stores a DTC, the ABS warning and slip indicator lights will come on.
If any of the indicators remains on or does not come on, proceed to troubleshooting for the light circuits listed below.

TR(A)C OFF indicator light circuit (Does not come on)	Refer to TRAC OFF Indicator Light does not Come ON [06/2016 - ]
VSC OFF indicator light circuit (Remains on)	Refer to VSC OFF Indicator Light Remains ON [06/2016 - ]
VSC OFF indicator light circuit (Does not come on)	Refer to VSC OFF Indicator Light does not Come ON [06/2016 - ]
TRACK indicator light circuit (Remains on)	Refer to TRACK Indicator Light Remains ON [06/2016 - ]
TRACK indicator light circuit (Does not come on)	Refer to TRACK Indicator Light does not Come ON [06/2016 - ]
Slip indicator light circuit (Remains on)	Refer to Slip Indicator Light Remains ON [06/2016 - ]
Slip indicator light circuit (Does not come on)	Refer to Slip Indicator Light does not Come ON [06/2016 - ]
Hill start assist indicator circuit	Refer to Hill Start Assist Indicator Circuit [06/2016 - ]

When the ignition switch is turned to ON, check that the brake warning, TR(A)C OFF indicator, VSC OFF indicator and TRACK indicator lights turn off after 3 seconds.
When the engine is started, check that the ABS warning and slip indicator lights turn off after 3 seconds.

SENSOR CHECK USING TEST MODE (SIGNAL CHECK)

HINT:

DTCs are stored if any malfunctions are detected during the check of each sensor.

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 neutral.
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.
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.
  
  HINT:
  - The sensor check may not complete if wheelspin occurs.
  - The speed sensor check may not complete if the speed sensor check is started while turning the steering wheel or spinning the wheels.
  NOTE:
  After the ABS warning light goes off, 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).
2. Check that the ABS warning light goes off.
  HINT:
  - The ABS warning light goes off when the sensor check has completed.
  - The ABS warning light comes on immediately after a malfunction has been detected during the speed sensor check.
3. Stop the vehicle.
  HINT:
  
  When the sensor check has completed, the ABS warning light goes off.
  
  NOTE:
  If the sensor check has not completed, the ABS warning light will come on and the ABS system will not operate.
End of Sensor Check
1. If the sensor checks have completed, the ABS warning light goes off.
  NOTE:
  If the sensor checks have not completed, the ABS warning light come on and the ABS system will not operate.
Reading Sensor Check DTCs
1. Read the DTC(s) by following the Techstream screen.
  NOTE:
  - If only DTCs other than Test Mode sensor check DTCs are displayed, repair the malfunctions and clear the DTCs.
  - If Test Mode sensor check DTCs and other DTCs are displayed or if only Test Mode sensor check DTCs are displayed, repair the malfunctions, clear the DTCs, and perform Test Mode inspection again.
  HINT:
  
  See "Sensor Check DTCs".
2. Turn the ignition switch off and disconnect the Techstream.
