U0537 code meaning
Invalid Data Received From Column Lock Module
What U0537 means
The column lock module drives the electric bolt that blocks the steering shaft when the car is parked and frees it before the engine may start. U0537 records that a partner module, such as the body controller or keyless start unit, received lock status messages it cannot trust. No manufacturer explains this exact code publicly. Related bulletins show how tightly the lock depends on timing and authentication: GM bulletin 16-NA-091 (ATS, CTS, XTS) reprogrammed the module after a Service Column Lock message with B2897, caused by door and power-mode changes within 100 to 300 ms, and Stellantis case S2408000110 (Wrangler 2024) lists implausible ignition, speed and coded BCM messages seen by the lock itself, with 10 to 16 V required. Possible effects: no start, column stays locked or a warning. U0236 is the lost-communication code.
U0537 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0537
- Engine does not start or start is refused
- Steering wheel remains locked
- Steering column lock service message
Common causes of U0537
- Most likelyColumn lock module software or calibration fault (reprogramming)
- PossibleWeak 12 V battery or voltage drops during start
- PossibleLock module not paired/learned to the body or immobilizer module after replacement
- Less likelyMechanical or internal fault of the lock actuator
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0537 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 37 | The exact fault in that area. |
What to do next
- Note U0537 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 U0537
What does U0537 mean?
U0537 means "Invalid Data Received From Column Lock Module". The column lock module drives the electric bolt that blocks the steering shaft when the car is parked and frees it before the engine may start. It is a generic code, so it means the same on every make.
Is it safe to drive with U0537?
U0537 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0537 fail an emissions test?
U0537 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 U0537 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. This is a job for a workshop.
Will U0537 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
