Differences between ABS 5.3 and ABS/TC 5.3

ABS 5.3 = 3-channel system (diagram: see Figure ).

ABS/TC 5.3 = 4-channel system (diagram: see Figure ).

The essential distinguishing features between ABS and ABS/TC are:

• Number of brake lines at intermediate piece (No. 8 / Figure 181 - 96): ABS 5.3 = 3 brake lines ABS/TC 5.3 = 4 brake lines
• TC off switch for switching driving stability control on and off is not available on vehicles with Solo ABS (ABS 5.3).
• TC (ASR/ABD) warning light and TC (ASR/ABD) function light (information light) in vehicles with ABS/TC. These lights light up when the ignition is switched on (lamp check). In vehicles with ABS 5.3 (Solo ABS) these lights are not fitted in the instrument cluster. A figure showing the warning lights and the function light is shown on Figure .
