Hi
I’ve got an issue where I have a dsc code
And on my drive I have dsc and tpms failure with code 5E30 on ISTA. I’ve also checked inpa values on my abs sensors and they are all reading correctly. Any help or ideas is appreciated.

The DSC sensor is located under the front passenger seat, underneath the carpet. They usually fail because of water damage.

Attached are ISTA ScreenPrints showing wiring diagram (SSP), Location, & Connector View of B9801 DSC Sensor.
Also attached are ISTA Diagnosis Scan ScreenPrints from my 3/2007 328xi showing Values at Rest, for DSC Sensor.
Some diagrams appear to show LL instead of RL (RHD) configuration.
Also, pdf: Fault Memory & Test Plan, explaining HOW to view various ISTA Screens, with ScreenPrint Examples.
