Central warning lamp
The central warning lamp lights up when a fault occurs in a system having to do with the car's safety.
The lamp is supplied with current (+15 circuit) from the main instrument unit and grounded by the MIU's control module when one of the following warning or indicator lamps lights up:
- Warning lamp, AIRBAG
- Engine oil pressure warning lamp
- Warning lamp, charging
- Warning lamp, brake fluid level
- Warning lamp, handbrake
- ABS warning lamp
The handbrake lamp lights the central warning lamp if the speed passes 5 km/h from a speed below 5 km/h.
Common to the above lamps is that they are supplied with current (+15 circuit) in the main instrument unit and grounded through the relevant component/system.
The central warning lamp also lights up when:
- Coolant temperature exceeds 129°C
At the same time as the central warning lamp comes on, the main instrument unit will send bus information to SID to activate the acoustic signal. This does not take place when the ignition is switched on as the lamps are only tested at this point. The engine speed must exceed 310 RPM for this request.
