- Disconnect the right high beam headlamp relay K132 connector.
- Use the DMM in order to measure the voltage between terminal 4
of the right high beam headlamp relay K132 connector and a known good
ground.
- Use the DMM in order to measure the voltage between terminal 2
of the right high beam headlamp relay K132 connector and a known good
ground.
Is the measured voltage for both measurements within the specified value?
| B+

- When the high beam switch is pressed, B+ is input into terminal A4
of the BCM connector C1. The BCM then pulls terminal C8 of connector C2
low.
- Use the DMM in order to measure the voltage between terminal 6
of the right high beam headlamp relay K132 connector and a known good
ground.
Is the measured voltage equal to the specified value?
