Installation Guidelines for the TABS-6 4S/2M Axle ABS Configuration:
• MOD1 (TABS-6 ABS Unit) controls the wheel(s) of a primary axle(s).
• MOD2 (BR9235™ Modulator Unit) controls the wheels of an additional axle(s).
• 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.
• SAL & SAR (Additional Sensors) senses the wheels that MOD2 controls, and are connected to the
18-pin connector on the TABS-6 ECU.
• For lift axle applications, MOD2 controls the wheels for the lift-able axle
