Ground Circuits

WARNING: This page is about a different car, the 2003 Chevrolet Tracker. However, it is still accessible from the selected car via links, so may be relevant.

PCM is located in right rear corner of engine compartment. Check PCM connectors for corroded or loose connections. Repair as necessary. Disconnect PCM connectors. Using DVOM, measure resistance between negative battery terminal and PCM harness connector ground terminals. See Figure-Figure or Figure-Figure . If resistance is more than 5 ohms, repair open in affected ground circuit. If resistance is 5 ohms or less, ground circuits are okay.
