{: ) Your stabilitrak system may not work properly. The vehicle need to be scanned for trouble codes. In case you get a C0196 code, the recommendation is to reprogram the electronic brake control module. I hope that's the only cause.

Wire resistance varies significantly by manufacturer and application anywhere from a few ohms to 1000 to 3000 ohms/ft.

Engine manufactures have a nominal resistance per length (typical) recommendation and a maximum limit.

The typical maximum is 10,000 ohms.

Suggest you compare wire resistance of all wires. Any wire that is more than double the others would be suspect.

What you can't measure with an ohm meter is breakdown voltage (leakage) of the dielectric. Plug wires don't last forever and on modern vehicals should be replaced at 75k to 100k miles minimum.
