Test M: The High Beam Indicator Is Never On

PINPOINT TEST M: THE HIGH BEAM INDICATOR IS NEVER ON

M1-M3:

M3-M6:

Normal Operation
When the high beams are turned on, the smart junction box (SJB) sends a voltage signal to the instrument cluster through circuit SBR14 (BN/RD) to illuminate the high beam indicator. The instrument cluster provides the bulb ground through circuit GD161 (BK/YE).

Possible Causes
- Bulb
- Circuit SBR14 (BN/RD) open
- Circuit GD161 (BK/YE) open
- SJB
- Instrument cluster
