MODE F4: OBD CONTROLS

On-Board Diagnostic (OBD) controls mode provides fast access to output controls supported by the vehicle

OBD system. Certain vehicle systems allow the tester to command an output or actuator device to turn on

and off. The tester that is used with this software is capable of bi-directional communication which controls

the device under test, or it can cause the device under test to change state by controlling CAB input/output

electronics. The specific outputs you can control depend on the vehicle selected. Providing quick and

efficient diagnostic software tools is the purpose of this mode.

There are certain constraints to controlling some of the vehicle outputs. Some are determined by the vehicle

ABS controller, and some are determined by the tester.

SUBMODE F0: BLEED BRAKES

The Bleed Brakes procedure is used to perform a complete brake system bleed on the Teves and Kelsey

Hayes 4-wheel disc brake ABS systems. The procedure of bleeding involves a standard brake bleeding

procedure followed by this scan tool procedure to cycle and bleed the CAB pump and the solenoids. A

second standard brake bleeding procedure is then required to purge any remaining air from the system.
