Check the control switch on the instrument panel lighting
Measure the voltage at all poles (except O D). If the voltage is different from that specified in Table 7.8, check the box in the <validator> elements and the associated wiring harness. Disconnect the connector of the control light switch on the instrument panel. Make sure that continuity at terminal D is the specified in the table voltages at the terminals.
