Ground Circuits
WARNING: This page is about a different variant/trim than selected.
- Using an ohmmeter, check for continuity to ground on PCM/VCM ground terminals. See POWERTRAIN CONTROL MODULE (PCM) table. Resistance should be zero ohms. If not, repair open to ground.
- Connect negative lead of a voltmeter to a good ground. Backprobe positive lead of voltmeter to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If voltmeter reading is more than one volt, check for open, short to voltage, corrosion or loose connection on ground circuit.
