NOTE:
The following numbered steps refer to circled numbers on diagnostic chart. See Fig 1
. For circuit identification, see Fig 2
.
- System misdiagnosis may result if the proper diagnostic sequence is not followed.
- A visual inspection of connector cavities and OSM pins for obvious connection problems may result in identification of the fault without further diagnosis.
- Assure proper power supply to OSM.
- Assure proper ground to OSM.
- Assure proper OSM address.
- Hazard flashers will increase data line activity, typical voltages will be between 0 and 5 volts and constantly changing. This will help identify if the OSM or data line is the problem.
