Circuit Board Replacement

IMPORTANT: The circuit board is fragile, handle with care. Hold it by its edges when installing. Use a grounding strap during installation of circuit board.

NOTE: All circuit boards in the central electronics box (CEB) are removed in the same way except for the DASH/Control Unit circuit board (H). Set new DASH/Control Unit circuit board to old calibration switch settings. To eliminate damage from static electricity, keep all new replacement boards in their protective packaging until ready to install.

1. Open access door and brush out any dust. Remove cover to CEB box.

2. Loosen cap screw (A) and disconnect connectors (B). Remove connector by moving in a back and fourth motion until connector comes freed from socket.

3. Release latches (C). Remove CEB box to access selected circuit board.

4. Squeeze locking clips on circuit board and slide from mounting bracket.

NOTE: Be certain pins to all connectors are properly seated prior to installation.

5. Install circuit board in reverse order.
