Connect an ohmmeter between battery negative terminal and:
- terminal 36 on break-out box
- terminal 37 on break-out box
In both cases the ohmmeter should read 0 ohms.
OK - Calibrating ground terminals, continued
Not OK - Checking for an open-circuit

Calibrating ground terminals, continued
- Ignition OFF.
Measure with an ohmmeter between the battery negative terminal and position A:3 on the 4-pin connector.
The ohmmeter should read approx. 0 ohms.
OK - FAULT FOUND
Not OK - Checking for an open-circuit, contact resistance and oxidation
