Fuel Pump Control Module
Caution:
- Turn the ignition OFF when installing or removing the control
module connectors and disconnecting or reconnecting the power to
the control module (battery cable, powertrain control module (PCM)/engine
control module (ECM)/transaxle control module (TCM) pigtail, control
module fuse, jumper cables, etc.) in order to prevent internal control
module damage.
- Control module damage may result when the metal case contacts
battery voltage. DO NOT contact the control module metal case with
battery voltage when servicing a control module, using battery booster
cables, or when charging the vehicle battery.
- In order to prevent any possible electrostatic discharge damage
to the control module, do no touch the connector pins or the soldered
components on the circuit board.
- Remove any debris from around the control module connector surfaces
before servicing the control module. Inspect the control module
connector gaskets when diagnosing or replacing the control module.
Ensure that the gaskets are installed correctly. The gaskets prevent
contaminant intrusion into the control module.
- The replacement control module must be programmed.
Procedure
- Remove the fuel pump control module from the module
bracket.
- If replacing the fuel pump control module, refer
to Control Module References for programming
and setup.
