Ground Circuits

  1. Measure resistance to ground on ECU terminals A23, A24, A26, and B2. Resistance should be zero ohms. If not, repair open to ground.
  2. Using a DVOM, connect negative lead to a good ground. Backprobe each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If voltmeter reading is greater than one volt, check for open, corrosion, or loose connection on ground lead.
