(a) Check connection of blower switch. If connection does not conform to specification, replace integrated control panel assembly.
(b) Check lighting operation
Connect positive wire of storage battery to terminal D6, negative wire to terminal E, then check whether
illuminating lamp illuminates. If bulb does not illuminate, replace the bulb.
(c) Check connection of air conditioning switch
As shown in the table, check connection of terminal when switch is pressedA/C switch connectorTester connection Specification

conditioning switch.
(d) Check indicator work
Connect positive wire of storage battery to terminal 1, negative
wire to terminal 3, then check whether illuminating lamp
illuminates.
If connection does not conform to specification, replace
integrated control panel assembly.
