Place the system in test mode by removing "test mode" plug (1). Make sure that the parking brake is in the ON position.Note: On CB-634D machines, remove the "model config" plug. The plug is located near the fuse box. In order to access the plug on some machines, the side console cover may need removed. The plug should then be repositioned for better serviceability in the future.
Turn the key to the ON position. Do not start the engine.
If there are any fault codes, do not proceed to the next step. A series of long flashes and short flashes of the light for the parking brake will indicate fault codes. Refer to Table 1 for the fault codes.
