900 SE Convertible V6-2489cc 2.5L DOHC EFI (1997)
Main Relay (Computer/Fuel System): Description and Operation
Main Relay.
When the ignition switch is turned to the ON position, current is applied to pin 56 of the control module which grounds pin 27 and so causes the main
relay to operate. Simultaneously, pin 54 of the control module is supplied with power from pin 87 of the main relay.
NOTE: When the ignition switch is turned to the OFF position (from the ON position) the main relay remains operated for a further five seconds or so
if the coolant temperature is above -40°C (25°F). At lower temperatures the main relay remains operated for about 30 seconds.
