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 / 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) MIL  and TC (ASR/ABD) function light  (information light) in vehicles with ABS/TC.  These lights are lit when the ignition is switched on (lamp check).

  In vehicles with ABS 5.3  (Solo ABS) these lamps are not fitted  in the instrument cluster.

  A figure showing the warning (MIL) and function lights is on COMPONENT ARRANGEMENT (ABS 5.3 AND ABS/TC 5.3) .
