Circuit/System Description
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The ECM uses inputs from the following components to verify the current gear ratio:
- B115 Vehicle Speed Sensor
- B25B Clutch Pedal Position Sensor
- B26 Crankshaft Position Sensor
- B227 Gear Position Sensor
If these inputs do not report the same gear ratio, a DTC will set.
