In intermediate level ESC systems, ABS will be disabled, or the computer will actively lock the wheels when brakes are applied. In these systems, or in vehicles without ABS, the performance in emergency braking in slippery conditions is greatly improved as grip state can change extremely rapidly and unpredictably off-road when coupled with inertia.
When a valve is clogged it is unable to open, close, or change position. An inoperable valve will prevent the system from modulating the valves and controlling pressure supplied to the brakes. Electronic control module Pump The pump in the ABS is used to restore the pressure to the hydraulic brakes after the valves have released it.
(GM did not use the term OBD 1.5 in the documentation for these vehicles — they simply have an OBD and an OBD-II section in the service manual.) For example, the 1994–1995 model year Corvettes have one post-catalyst oxygen sensor (although they have two catalytic converters ), and have a subset of the OBD-II codes implemented.
Modern vehicles have many ECUs, and these can include some or all of the following: engine control module (ECM), powertrain control module (PCM), transmission control module (TCM), brake control module (BCM or EBCM), central control module (CCM), central timing module (CTM), general electronic module (GEM), body control module (BCM), and ...
In each e-caliper a controller uses the brake command (received from ECU) as a reference input. The controller provides drive control commands for a power control module. This module controls three phase drive currents for the brake actuator which is a permanent magnet DC motor, energised by 42 V sources. In addition to tracking its reference ...

The pressure of the rear wheels are approximated to the ideal brake force distribution in a partial braking operation. To do so, the conventional brake design is modified in the direction of rear axle overbraking, and the components of the ABS are used. EBD reduces the strain on the hydraulic brake force proportioning valve in the vehicle.
The Pontiac G6 is a mid-size car that was produced by General Motors under the Pontiac brand. It was introduced in 2004 for the 2005 model year to replace the Grand Am.. The G6 shared the GM Epsilon platform with the Chevrolet Malibu, Saab 9-3 and other General Motors vehicles.
