ABS system FL/Super

For the technical things.

ABS system FL/Super

Postby 164 TD » Sat Feb 26, 2011 12:58 pm

With the introduction of the FL/Super models, the Boschmade ABS 2B used in the first series 164 was replaced by Bosch more advanced ABS 2S.
Major differences where the logic to prevent skidding, the intergrated ABS computer in the ABS unit(The 2B version had the computer in the centerconsole) and the possibillity to interrogate the ABS for faults by means of a flashingcode (2B needed a breakoutbox for troubleshooting)

Around 1995, the 2S version of the ABS was superseeded by the ABS 5.3 system.The 5.3 system had even better logic and supplementary faultcodes.

The top ABS computer is the 2S series, the bottem one the 5.3 series.

Nice topic Arjen,

What about the ABS for the QV and Q4 are they the same as mentioned above?

Great info, Arjen. This fits well with the drawing I have seen of the 5.3 version.

I believe that the Q4 version has an 'i' to the version name. The 4WD is using information from the ABS to individually brake wheels separately, if I remember correctly.

My 164TS is made 01.96 (from ePer) with Bosch 2Si.
My ex 164TD was made later in 1996, i don't know which month, it was with 5.3
My dad's 164TS 1997 is also with 5.3.

I think, that 5.3 is installed after the spring of 1996.
