DESCRIPTION
The RABS II warning light should automatically begin a flash-out sequence if the diagnostic connector is shorted to ground for at least one second. This flashout sequence can be observed by watching the REAR ABS light. There are a few conditions which will prevent the flashout from occurring. These must be resolved before continuing the RABS II repair process.

Possible Contributing Base Brake Component/Vehicle Wiring Concerns
- Burned-out brake tail lights
- Missing RABS II power (Circuit 601 [LB/PK] and associated fuse)
- Shorted RABS II light circuit (Circuit 603 [DG])
- Incorrect module type (RABS I vs. RABS II)
