Replacing the
E-Pi
1. Remove the cover.
2. Locate and loosen the module retaining captive screw from the
manifold. Note that the module is designed so that the screw does not
need to be removed from the plastic piece.
3. Grab the module firmly and pull it straight out.
4. Align the replacement module with the pneumatic and electrical
connections. Press straight down into the manifold, and tighten the
retaining screw.
5. Electrical connections are a two-point contact system. The first contact
occurs when the connector is pushed onto the PCB male pin. The
second occurs as the barrel of the connector is pushed further onto the
pin. It may be necessary to use needle nose pliers to make the second
connection. If this is the case, grip the connector firmly above the
barrel section and push straight down. Refer to
Figure 4–2 .
The unit should operate without requiring calibration.
