Wondering if anyone has had issues with abs dsc and tpms lights being present on dash?

The warning lights are intermittent. initially presumed it was going to be a faulty abs sensor or the abs pickup ring. However after running a diagnostic check I’m not so sure. My first diagnostic test results…

5E14-CAN: Connection With Engine ECU Failed
5E19-CAN: Data Error From Engine ECU
5E1F- Vehicle Identification Number Different
5Е16-CAN Instrumentation

After clearing these codes I ran the car for a few miles with no warning lights. When the lights appeared again I ran another diagnostic test and the only code present was,

5D90-Wheel Speed Sensor Position Front Left

I’ve ran a live data test while driving and all wheel speed sensors are operating as expected.

Any info into this would be much appreciated!

Cheers!

Assuming you have R50/3 Both TPMS and ABS can mean steering angle sensor, "angle implausible" the ecu checks each wheel speed against the steering angle, as when the steering is turned the wheels will be rotating at different speeds. If the angle/speeds don't add up you'll get the error.

Check your turrets for deformation as they are weak and will dome up causing this error due to the weird geometry.

The bolts on the top mount should be parallel if they're wonky like the attached you need some new mounts and a big hammer.

Thanks for the info, much appreciated. I replaced the wheel speed sensor and it corrected my issue. Easy stuff.
