Technical Description
The Electronic Brake Control Module (EBCM/ABS module) has detected an open circuit, short to voltage/ground, or an out-of-range voltage feedback from the primary hydraulic brake pressure sensor circuit. The ECU continuously monitors the 5V reference rail, ground circuit integrity, and rational sensor voltage output relative to brake pedal actuation.
Possible Causes
1. Defekt bromstryckgivare (internt piezoresistivt elementfel eller spänningsdrift i ABS-hydraulblock/huvudcylinder)
2. Oxiderade kontaktstift, böjda stift eller kabelbrott i ledningsmattan mellan ABS-styrenhet och trycksensor
3. Internt hårdvarufel/kallödning på kretskortet i ABS/EBCM-styrenheten
Recommended Solution
Workflow
Mechanic's Tip
Before replacing expensive components, always double-check wiring and connections. 80% of all sensor faults are actually due to corroded contacts or broken wires.
