Stratus V6-2.5L VIN H (1997)
Fig. 1 ASD And Fuel Pump Relay Terminals
CIRCUIT OPERATION
Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays, terminal 30 is connected to battery voltage at all
times.
The PCM grounds the coil side of the relay through terminal number 85.
Terminal number 86 supplies voltage to the coil side of the relay.
When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to terminal 30. This is the Off position. In the off
position, voltage is not supplied to the rest of the circuit. Terminal 87A is the center terminal on the relay.
When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30. This is the On position. Terminal 87 supplies
voltage to the rest of the circuit.
Power for the coil and contact side of the relay is provided by circuit A14. This circuit is HOT at all times and protected by a 20 amp fuse located
in cavity 5 of the PDC.
The Powertrain Control Module (PCM) controls the ground path for the relay on circuit K51. This circuit connects to cavity 67 of the PCM
connector.
When the relay is energized, the contacts internal to the relay close connecting circuits A14 and A142. The A142 circuit is spliced and provides
power to the fuel injectors, generator, electronic EGR transducer solenoid, and the ignition coil.
The A142 circuit is also spliced and connects to the PCM connector, cavity 6. This input is used for ASD sense by the PCM.
HELPFUL INFORMATION
Check the 20 amp fuse located in cavity 5 of the PDC.
