1 min read

CUSTOMER CONCERN

READY mode intermittently fails, the navigation display flickers, and DTCs P3000, C1545, B1585, B1551, and B15F9 are stored.

CAUSE

The key-fob battery was too weak for reliable smart-key recognition, producing intermittent startup and electrical symptoms.

CORRECTION

Remove and replace the key-fob battery, clear the stored DTCs, and verify consistent smart-key recognition, READY mode, and navigation-display operation.
