RDW Control Module
The RDW control module is located behind the glove box in the control module carrier. in addition to the four wheel speed signals, the module receives power (KL 15), ground (KL 31) and a ground signal input from the set/push button switch in the console.
The control module is connected to the K-Bus for:
- Output display in the check control matrix
- Diagnostic communication through the instrument cluster with the DISplus tester or MoDiC
The control module processes the wheel speed signals and stores rolling circumference values for determining pressure losses in one or more tires.
