SYMPTOM
BUS BIAS LEVEL TOO HIGH

TEST NOTE
This symptom is diagnosed using the test BUS BIAS LEVEL TOO HIGH.

POSSIBLE CAUSES
- SKIM- bus bias too hi/low
- Instrument cluster ground circuit open
- Powertrain control module causes CCD bus bias too hi/low
- DLC CCD bus (+) circuit shorted to GND
- Instrument cluster CCD bus (-) circuit open
- Instrument cluster CCD bus (-) circuit shorted to GND
- CMTC causes CCD bus bias too hi/low
- Transmission control module causes CCD bus too hi/low
- Remote keyless entry causes CCD bus bias too hi/low
- DRB or DRB cable affecting bus bias voltage
- Instrument cluster causes CCD bus bias too hi/low
- Instrument cluster CCD bus (+) circuit open
