Test E: The Headlamps Are On Continuously
PINPOINT TEST E: THE HEADLAMPS ARE ON CONTINUOUSLYNormal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the headlamp switch routes voltage to the multifunction switch through circuit CLS24 (BN/WH).
When the multifunction switch is in the LOW BEAM position, the multifunction switch routes voltage to the smart junction box (SJB) through circuit CLF18 (BU/WH). The SJB then routes the voltage to the LH and RH low beams through circuits CBP04 (VT) and CBP03 (GY), respectively.
When the multifunction switch is in the HIGH BEAM position, the multifunction switch routes voltage to the SJB through circuit CLF27 (GN/BN). The SJB then routes the voltage to the high beams through circuit CBP14 (VT/OG) and to the instrument cluster through circuit SBR14 (BN/RD).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Headlamp switch
- Multifunction switch
- SJB
