U0541 code meaning
Invalid Data Received From Entrapment Control Module B
What U0541 means
Entrapment control module B is the second slot for a separate pinch-protection unit. Some designs detect a person before contact: a capacitive strip changes its electric field as a hand approaches, and the attached electronics pass the result to the closure controller either as a switched output or as LIN or SAE J2602 data, as a review of tailgate anti-pinch approaches explains; patent US20030151382 likewise combines a capacitive field with a position sensor. U0541 is stored when frames from such a unit B are malformed or implausible. No manufacturer publishes the code. FCA's case S2208000106 shows how confusing two-sided sensing can be: its left and right liftgate pinch sensor codes may point to the wrong side, so check both connectors. U0240 covers complete loss of module B.
U0541 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0541
- Power liftgate or sliding door stops or reverses without contact
- Automatic closing refused with a warning
Common causes of U0541
- PossibleCapacitive sensor strip or its electronics delivering implausible values
- PossibleSensor connector not fully seated or corroded
- Less likelySoftware or calibration of module B not matching after replacement
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0541 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 41 | The exact fault in that area. |
What to do next
- Note U0541 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 U0541
What does U0541 mean?
U0541 means "Invalid Data Received From Entrapment Control Module B". Entrapment control module B is the second slot for a separate pinch-protection unit. It is a generic code, so it means the same on every make.
Is it safe to drive with U0541?
U0541 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0541 fail an emissions test?
U0541 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 U0541 to fix?
Difficulty: hard. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will U0541 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
