Circuit/System Description

The Transmission Shift Lever will provide electrical signals based on customer input to the Chassis Control Module, where the customer shift request will be determined. The shift lever position is determined by 2 internal sensors that each transmit an X and Y coordinate signal. All 4 signal circuits are inputs to the Chassis Control Module and are diagnosable for a high duty cycle condition, low duty cycle condition, and a signal performance condition. These DTCs will put the vehicle in Latent Fault Mode. Refer to Latent Fault Mode Description .
