Electronic Gear Shift - Position Not Learned
The shift-by-wire controller did not complete the position learning routine for the gear selector. Without learned end stops the controller cannot map selector positions to gear requests.
Affected components
- Electronic shifter
- Control module
Common causes
- High likelihood: Learning routine aborted by other DTC or low voltage
- Medium likelihood: Shifter replaced without subsequent learn
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
- The malfunction indicator lamp may illuminate
