CAUTION:
Comply with the following cautions to prevent any error and malfunction.
- Before removing and installing any control units, first turn the ignition switch to the LOCK position, then disconnect both 12V battery cables.
- After finishing work, confirm that all control unit connectors are connected properly, then re-connect both 12V battery cables.
