ASR / TCS - Description

1.6 TS, 2.0 TS, 1.9 JTD 16V

Description

The antilock braking and anti-slip regulation systems (BOSCH 5.7 ABS with ASR) modulate brake pressure sent to the wheels to prevent loss of grip under all tyre and road surface conditions by cutting in automatically whenever one or both drive wheels begin to slip.

The ASR system increases vehicle stability and active safety by controlling drive wheel slip. If slip is caused by excessive power transmission, it cuts in to reduce engine power through communication with the engine management control unit. if slip is detected at a single wheel, the system cuts in to brake the slipping wheel by acting on the modulation solenoid.

ASR comes on automatically whenever the engine is started. The system can be deactivated by operating a button on the central console. When the system is off, a led on the button comes on at the same time as a warning light on the control panel.

The warning light flashes when the system cuts in to notifiy the driver that the ASR system has cut in due to road surface grip conditions.

The warning light comes in in fixed mode when the control unit detects an error in the ASR function.
