•
blocked signal in UP / blocked signal in DOWN / signal not plausible
Error cause:
•
If the signal is blocked in UP: internal spring of the switch blocked in UP
•
If the signal is blocked in DOWN: internal spring of the switch blocked in DOWN
•
If the signal is not plausible. this symptom is mainly caused by a gear shift (UP or DOWN)
detected by the control unit without any change to the signal status (from "released lever"
to UP or DOWN)
Troubleshooting:
This error necessarily involves an internal mechanical anomaly at the sensor; therefore, replace the
component.
NOTES: The potential presence of the P1900 electrical error disables the recognition of the P1906
error.

Function:
To signal to the control unit the request for modi-
fication of the a-PRC system settings.
