RHEOSTAT
1. Disconnect the negative (-) battery terminal.
2. Disconnect the rheostat connector from the crash pad lower panel.
3. Check for intensity. If the light intensity of the lamps changes smoothly without any flickering when the rheostat is turned, it can be assumed that
the rheostat is normal.
