The general fault warning light (2) includes the following information/faults:

  • FIS intervention
  • Engine oil pressure sensor failure
  • Exterior lighting failure
  • Parking sensors failure
  • Engine oil pressure sensor failure
  • Robotized gearbox safety signals
  • Fuel locking operation
  • Fuel locking not available
  • ABS, ASR, and ESP fault

Brightness sensor

The control panel is equipped with a brightness sensor that detects day conditions and night conditions so that the car display illumination is managed accordingly. (see wiring n° 1 of Instrument panel)

Use of the key (+15) signal

The control panel receives:

  • Key signal from the network (+15 from BCM, CAN "KeySts" signal)
  • physical Key signal (from the pawl)

The instrument panel only uses the network key signal to switch off, while the physical key signal is needed to switch it on.

All the instrument panel system modules (Network, WakeUp, Diagnosis) only use the physical key.

Under BCM recovery conditions, the control panel no longer uses the network key and manages its operations using the physical key alone.

The figure below shows the rear view of the instrument panel, where the connector for the car wiring connection is located.
