C1002 on Fiat
ABS Hydraulic Pump Motor Circuit Open
C1002 on Fiat vehicles indicates abs hydraulic pump motor circuit open. Au7o has documented this code across 1 Fiat model — most commonly on 500. This chassis code means the ABS module detected an open (broken) electrical circuit to the anti-lock brake system's hydraulic pump motor. That pump motor builds and releases brake-line pressure during ABS, traction-control, or stability-control events, so the module continuously checks that it can power the motor. An 'open circuit' means current can't flow — usually a wiring, connector, ground, or motor fault. Your normal brakes still work, but ABS and related stability features will typically be disabled with warning lights on. Typical repair costs on Fiat range from $700 to $1,500, depending on the specific model and root cause.
Common Causes of C1002
- •Open or broken wiring to the pump motor
- •Corroded, loose, or disconnected connector at the ABS unit
- •Failed ABS pump motor
- •Blown fuse or faulty relay feeding the pump
- •Poor ground connection
- •Faulty ABS control module/hydraulic unit
- •Low battery voltage or charging system fault
