Test 2: Traction Systems Control Module Voltage Supply Circuit 30)

Using Adapter (202 589 03 63 00), connect Breakout Box (129 589 00 21 00) to traction control module. See Figure, Figure or Figure. Turn ignition switch to OFF position. Check voltage between terminals No. 57 and 82 at breakout box.
If battery voltage exists, system is okay at this time. If battery voltage does not exist, check wiring. See WIRING DIAGRAMS . On E300D, E300TD, E320, E420 and E430 models, check relay module fuse. On SLK230, check crash separation relay module. Replace as necessary.
