1. The Electronic Controller, a Signal Receiver and anIndicator (Fig. 3) can be seen by the below steps:• Remove the 2 caps and 2 screws at the bottom of theFront Grille. (Fig. 1)• Remove the Front Grille by releasing the 2 hooks at thetop of the Front Grille. (Fig. 1)• Remove the Control Board Cover by releasing the 2tabs at left, 1 tab on top and 1 tab at right side of theControl Board Cover. (Fig. 2)2. To remove the Electronic Controller:• Release the Particular Piece. (Fig. 3)• Release the hook that hold the Electronic Controller.(Fig. 3)• Remove the Control Board by:-− Releasing CN-REC/DISP connectors. (Fig. 4)− Releasing CN-FM connectors. (Fig. 4)− Releasing CN-STM connector. (Fig. 4)− Removing the Earth Wire screw. (Fig. 4)− Releasing the Intake Air Sensor. (Fig. 4)− Releasing the Piping Sensor.

Please usea high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).• Pb free solder will tend to splash when heated too high (about 1100° F/600°C).12.1.
