Test M: One Turn Signal/Hazard Lamp Is Inoperative/Always On

PINPOINT TEST M: ONE TURN SIGNAL/HAZARD LAMP IS INOPERATIVE/ALWAYS ON

Normal Operation
When the smart junction box (SJB) detects the multifunction switch in the LH TURN position, the SJB provides voltage through circuit CLS21 (BU/GN) to the LH front turn lamp. When the SJB detects the multifunction switch in the RH TURN position, the SJB provides voltage through circuit CLS25 (YE/VT) to the RH front turn lamp. Circuits GD123 (BK/GY) and GD120 (BK/GN) provide ground for the LH and RH front turn lamps, respectively. The rear turn lamps are controlled utilizing the rear stoplamp circuitry.







This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Joint connector
- Bulb holder (Edge)
- Headlamp assembly (MKX)
- SJB
