INSTRUMENTSE1 CIRCUIT OPERATION1 CIRCUIT OPERATION Engine Coolant Temperature Gauge The engine coolant temperature gauge sensor has the capability to sense from ±40C to +130C. Petrol and Diesel resistance valves are different. Both Petrol and Diesel sensors are interfaced to the Instrument Cluster (Z142) via the BeCM (Z238). The resistance value then being represented by an A/D data transfer generating the required angular deflection on this gauge. ] Fuel Gauge When the fuel...

WARNINGS AND INDICATORSE2 CIRCUIT OPERATION1 CIRCUIT OPERATION All warning Indicators are controlled by Data sent to the Instrument Cluster (Z142) from the Body Electrical Control Module (BeCM) (Z238). All data is transmitted via the serial data lines. The BeCM (Z238) will provide data based upon input from various sensors. Some warning lights may also be accompanied by a message which will appear in the message centre display on the instrument pack. Service Reminder Indicator (SERVICE ENGINE)...
