Check the condition and connection of the display connector (component code 1127) and of the navigation
computer 32-track connector (component code 662) (broken, oxidised, bent tabs).
Manipulate the wiring harness at the connectors to produce a change in fault status (present → stored).
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
With ignition on, check for + 12 V on the BCP3 connection of the component 1127 connector.
