Segment Check Failure

The segment check while entering diagnostics is for the purpose of illuminating all LCD displays of the instrument panel, climate control panel and driver information system. The turn signal indicators do not light during this check.

Further diagnosis should not be attempted unless ALL segments appear, as this could lead to misdiagnosis. If any portions of the climate control panel or driver information system are inoperative, the COMBO PANEL must be replaced (if entire display is blank). For diagnosis, perform SELF DIAGNOSTICS SYSTEM CHECK  before proceding.
