Engine Control Module: Description and Operation
Control Module Power Supply
+30:
Power (+30 circuit) is supplied via fuse 23 to control module pins 1 and 48.
The engine control module uses the +30 power supply for its memory.
The engine will not start unless power is supplied via the +30 circuit.
+15:
Power (+15 circuit) is supplied via fuse 13 and the anti-theft alarm's control module to pin 60 of the Trionic control module.
Applying power (+15 circuit) to pin 60 activates the engine control module.
The engine will not start unless power is supplied via the +15 circuit.
Programming, Manual/Automatic:
The Saab Trionic control module has the same part number for cars with a manual gearbox or automatic transmission.
When power is applied to pin 14 by the selection of a gear other than P or N, the control module is programmed for a car with automatic transmission.
On cars with a manual gearbox the circuit to pin 14 is open.
