Headlight Issues
When the headlight switch is in the “AUTO” position, the left headlight does not work. Error code 00979 is stored in the memory. The technician performed some basic checks of the electrical wiring and replaced the left bulb with a bulb from the right headlight, but the error persists.
1. The described problem affects all Yeti models up to 03/10 with xenon headlights. First, we recommend that personnel exercise caution when working on high-voltage components and follow all safety guidelines. If all voltage and ground connections are correct, we suspect that the fault is due to a failure of the ignition unit.
2. Before each repair, first check that the power supply is disconnected. Install a new headlight ignition unit on the headlight assembly (Figure 2.1). Clear the fault codes and check the operation of the headlight to confirm that the fault has been rectified.
