B0130 indicates a fault in the control circuit for the washer-fluid pump or solenoid that cleans an A/V or ADAS sensor (circuit B). The control module has detected an electrical problem—such as an open, short, or unexpected load—on the circuit that operates the sensor-cleaning washer jet.
The pump motor or solenoid valve that supplies fluid to the sensor cleaning jet can fail internally—open winding, seized armature, or stuck valve—causing the control circuit to report a malfunction.
An open, short-to-power or ground, chafed harness, water intrusion, or corroded connector pins between the control module and the washer pump/solenoid can set this circuit code.
Loss of power or ground to the washer pump/solenoid from a failed fuse, relay, or shared power distribution point can produce the same circuit-fault indication.
A blocked nozzle, kinked hose, or contaminated reservoir can stall or overload the pump, which sometimes triggers a control-circuit fault, though this is less common.
The body or ADAS control module may have a damaged driver for the washer circuit, but this is uncommon and should only be considered after the pump, wiring, and power supply are ruled out.
Usually yes. The code affects the sensor or camera cleaning circuit, not engine operation. The main concern is reduced cleaning performance for the affected sensor.
Probably not if the code reflects a true control-circuit fault. Low fluid can set level-related codes, but B0130 generally points to the pump/solenoid, wiring, or control driver.
No. B0130 is a body/ADAS washer-fluid control-circuit code, and the engine computer is almost never at fault. A control-module problem is possible but would involve the body/ADAS module and should be diagnosed last.
Yes. Once the underlying cause is repaired, the code can be cleared with a scan tool. If it returns, further electrical diagnosis is needed.
