CAUTION:
Do not perform active test while driving vehicle.
Make sure to completely bleed air from brake system.
The active test cannot be performed with the ABS warning lamp, TCS indicator lamp, SLIP indicator lamp and brake warning lamp are on.
ABS warning lamp, TCS OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on during active test.
Operation Procedure
NOTE:
When active test is performed while depressing the pedal, the pedal depression amount will change. This is normal. (Only solenoid valve and ABS motor)
"TEST IS STOPPED" is displayed 10 seconds after operation start.
After "TEST IS STOPPED" is displayed, to perform test again, touch "BACK" to restart the process.
Solenoid Valve
NOTE:
The example shown is for front right wheel. The procedure for the other wheels is the same as given below.
When performing an active test of the ABS function, select the "MAIN SIGNALS" for each test item.In addition, when performing an active test of the TCS function, select the item menu for each test item.
