U1504 on Chrysler
On Chrysler vehicles, U1504 is a network code for an implausible message length from the steering angle sensor
Severity: Inspect soon
The steering angle sensor feeds stability and brake systems, and owners report stability and airbag-related warnings and a stalling car with this code.
It gets more serious if:
- Stop: Stop if the engine stalls or will not restart, shifter lights flash, or the airbag or stability warnings come on: pull over safely and arrange a tow.
