ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

NOTICE:

If using a dropper to adjust the fluid amount, make sure that the dropper has not been used with mineral oils, water or deteriorated brake fluid. Sealed areas may deteriorate and lead to fluid leaks, or the fluid may deteriorate and lead to decreased efficiency.

HINT:

If the brake fluid level is lower than the MIN line, inspect for brake fluid leaks and brake pad wear. After repair or replacement, adjust the brake fluid level in the reservoir as specified below.

PROCEDURE

1. INSPECT AND ADJUST FLUID LEVEL IN RESERVOIR (When Using the Techstream)

(a) Connect the Techstream to the DLC3 with the power switch off.

(b) Check that the shift lever is in P and the parking brake is applied, and turn the power switch on (IG).

(c) Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Utility / ECB (Electronically Controlled Brake system) Utility / Zero Down.
