CHECKING THE GROUND TERMINAL FOR THE STEERING WHEEL MODULE
Checking the ground terminal
- Ignition off

- Switch off all equipment that takes power from the battery (courtesy lighting, radio etc).
Connect an ohmmeter between terminal #16 on the breakout box and the battery negative terminal.
To connect the breakout box, see Connecting the breakout box. ZZZZZZ
The ohmmeter should read approximately 0 ohms
OK - Testing Complete
Not OK - Continue below.
Checking for open-circuits, contact resistance and oxidation
For the control module, check ground terminal 31/84 and the wiring connected to it. Check for an open-circuit and check for contact resistance and oxidation. Checking Wiring and Terminals - Permanent Faults
