Your going to need a good scanner to see what the issue is did you try and disconnect battery for a while?

When i was chasing my serv 4wd light I unplugged the ABS to clean connections and upon turning it back on i had a ton of lights and codes… had to disconnect battery to clear codes that my scanner couldn’t clear.
So as above post said try that first.

I think this question can be a bit complex but you can start looking at few things . Mark these check boxes as done and checked .

1. Electrical Connection Issue: It's possible that during the replacement of the ABS module, there was a loose or improperly connected wire or connector. Check all the electrical connections related to the ABS module and ensure they are securely connected.
2. Faulty Speed Sensor: The ABS system relies on speed sensors to determine wheel speed. If one of these sensors is damaged or not properly connected, it can affect both the ABS system and the speedometer. Inspect the speed sensors and their connections for any issues.
3. Module Compatibility: Ensure that the replacement ABS module is compatible with your vehicle's make, model, and year. Using an incompatible module could lead to unexpected issues with various vehicle systems.
4. Diagnostic Scan: If you're unsure about the cause of the problem, it's a good idea to perform a diagnostic scan
5. Wiring Damage:
6. Software Calibration: Some ABS modules may require software calibration or programming after installation. Make sure that the new ABS module has been correctly calibrated for your specific vehicle.
7. Fuse Check: Check the vehicle's fuses related to the ABS system, speedometer, and park aid. A blown fuse could be causing these issues.
