Checking the Ground Terminals, Brake Control Module

Checking the ground terminals, brake control module

Checking the ground terminals








- Ignition off
- Connect the breakout box
- Control module disconnected.
- Switch off all equipment that takes power from the battery (for example, courtesy lighting, radio etc.).
Check the resistance between the battery negative terminal and breakout box terminal #16 and between the battery negative terminal and breakout box terminal #46. The resistance must be 0 ohms.
Check the ground terminal 1/1 (battery negative terminal) if the resistance is incorrect. Check for an open-circuit and contact resistance.
Check the cable between ground terminal 31/95 (left-hand wheel arch) and brake control module terminals #16 and #46. Check for an open-circuit. Check for contact resistance.
