Power Supply

Battery Voltage (+30 circuit)










+30 current is supplied via fuse 35 (22a) to the main instrument unit pin 1.
The control module uses current from the +30 circuit for its memory.

Battery Voltage (+15 circuit)
+15 current is supplied via fuse 17 (22a) to the main instrument unit pin 2.

The main instrument unit is activated by current from the +15 circuit.

Diagnostics
If there is no current supply from the +30 circuit, the trip meter will be zeroized every time the ignition is switched off.

If no +15 current is present, the main instrument unit will not be activated. The engine will not start, as bus communication has not been activated.

The function has no diagnostics.
