Test A: No Communication With the Anti-lock Brake System (ABS) ModuleNormal Operation
Fused battery voltage is supplied to the anti-lock brake system (ABS) module from battery junction box (BJB) fuses 6 (40A) and 33 (30A) along circuits SBB06 (BN/RD) and SBB33 (RD) respectively. Fused ignition voltage is supplied to the ABS module from smart junction box (SJB) fuse 18 (10A) along circuit CBP18 (GY/OG) and ground is provided along GD120 (BK/GN).
The operating voltage required to supply the ABS module, hydraulic pump and isolation valves is in a range between 10 and 17 volts.
