U0537Invalid Data Received From Column Lock Module
- Generic OBD-II code · Network
- How the car detects it
- 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.
