Step 2

              Open the module cover               

• Open Module being careful not to break off these two tabs

Step 3

              Seperate board from the box               

• The board lifts straight up out of the box

Step 4

              Re-solder. You will find this joint will not easily accept solder.               

• The tip of the screw driver is at the joint that has failed. Generally I re-flow the solder on all 7 of the larger diodes and both of the blue color resistors in between the diodes. I also re-flow all the joints on the black wire harness connector.

Step 5

              Clean the board               

• If the solder will not flow smoothly on any of the joints, the joint will require cleaning. Mark the direction the diode is in and remove the solder from the joints using a solder sucker. Remove diode. Add flux and brush the area being very careful not to damage the eyelets on the board.

Step 6

              Reassemble and start the vehicle.               

• You may even have to use a pencil eraser. Be sure not to damage the eyelets on the board. After it is clean reinstall the diode in the same direction (silver band toward the edge of the board) and solder in place. Place the board back inside the box and close the lid. Plug it into the harness and start the engine.

To reassemble your device, follow these instructions in reverse order.
