Shift Solenoid 1 Performance Conditions
Ford · transmission
Data confidence80%
The control module detected a fault associated with the Shift Solenoid 1 Performance Conditions circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
Steering wheel control information fault
PSA · steering
Data confidence72%
The stored code identifies a fault of the Steering wheel control information fault. Documented for the AL4 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
