Checking the ground terminal

Checking the ground terminal




- Ignition off
- Control module disconnected
- Switch off all equipment that takes power from the battery (courtesy lighting, radio etc).
Connect the breakout box.
Connect an ohmmeter between terminal #A2 on the breakout box and the battery negative terminal.
The ohmmeter should read 0 ohms.

Other information
- To connect the breakout box, see Connecting the breakout box. Accessory electronic module Connecting the Breakout Box, Accessory Electronic Module (AEM).





Is the value OK?
