B011B code meaning
Camera Washer Actuator S
What B011B means
B011B closes the row with actuator S. Electrically, each actuator in the row is a coil or motor switched by a module or a relay. HELLA's relay guide explains the switching side: a control coil on terminals 85 and 86 pulls in the armature and moves the contact from 87a over to 87, and some types carry a resistor or diode across the coil to tame the spike at switch-off. Asmo's US20120266926A1 energises its camera wash valve through a relay fed from the reversing-lamp circuit, so a fault there can disable the wash as well. An open coil, a sticking relay or a broken feed on this last actuator is what B011B points to. No public source ties S to a particular camera or reports B011B from a real vehicle.
B011B at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.2 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B011B
- Camera wash for the camera served by actuator S does nothing
- Wash may run continuously or not stop if a relay contact has welded
Common causes of B011B
- Most likelyCoil or motor of actuator S open or shorted
- PossibleRelay feeding actuator S sticking or with a burnt contact
- Less likelyBlown fuse or broken supply wire to the relay or actuator
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B011B means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 1B | The exact fault in that area. |
What to do next
- Note B011B and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about B011B
What does B011B mean?
B011B means "Camera Washer Actuator S". B011B closes the row with actuator S. It is a generic code, so it means the same on every make.
Is it safe to drive with B011B?
B011B does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B011B fail an emissions test?
B011B is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B011B to fix?
Difficulty: medium. A typical repair takes 0.2 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will B011B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
