Differences between ABS 5.3 and ABS/TC 5.3

ABS 5.3 = 3-channel system (diagram: see DIAGRAM: ABS 5.3 (3-CHANNEL SYSTEM)  ).

ABS/TC 5.3 = 4-channel system (diagram: see DIAGRAM: ABS / TC 5.3 (4-CHANNEL SYSTEM)  ).

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

• Number of brake lines at intermediate piece (No. 8 / see Figure ): 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 COMPONENT ARRANGEMENT (ABS AND ABS/TC)  .
