Installation Guidelines for the TABS-6 4S/2M Axle ABS Configuration:

o MOD1 (TABS-6 ABS Unit) controls the left “road-side” wheel(s) of a primary axle(s).

o MOD2 (Bendix® BR9235Modulator Unit) controls the wheels of an additional axle(s).

o SL & SR (Primary Sensors) senses wheels on the primary axle (always on the ground) that MOD1 controls, and are connected to the dedicated 2-pin connector on the TABS-6 ECU.

o SAL & SAR (Additional Sensors) senses the wheels that MOD2 controls, and are connected to the 18-pin connector on the TABS-6 ECU.

o For lift axle applications, MOD2 controls the wheels for the lift-able axle
