NOTE:
The following numbered steps refer to circled numbers on diagnostic chart. See Fig 1. For circuit identification, see Fig 2.
- If you were not directed here from Lighting Chart A-1, a wrong diagnosis could result if not performed first. See LIGHTING CHART A-1 in SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
- Visually inspect the cavities and pins of the OSM for obvious connection problems.
- Checks for proper power supply to the OSM.
- Checks for proper ground to the OSM.
- Checks for proper OSM address identification.
- Hazard flashers will increase data line activity. Typical voltages will be between zero and 5 volts and will be constantly changing. This will help identify whether the OSM or the data line is the problem.
NOTE:
When all diagnosis and repairs are completed, clear codes and verify operation.
