Notes on testing electronic components and system for damage resulting from an accident - AH42.00-P-0001-06B

Model 129, 140, 168, 170, 202, 203, 208, 209, 210.08, 210.28, 211, 215, 219, 220, 230, 240 

Handling ESP/SBC parts on vehicles involved in an accident 

If, because of the extent of the damage to the vehicle or the position and external appearance of the hydraulic unit after the accident, it is obvious that the hydraulic unit has sustained a heavy shock, it must be renewed.

Indications of this are e.g.:

• Hydraulic lines kinked
• Connections on hydraulic unit leaking
• Cables or plug connections damaged
• Metal block of hydraulic unit shows signs of damage
• Hydraulic unit detached from its bracket and cannot be easily reinstalled

Even if none of these are applicable the system must still be subjected to a rigorous function test.

The solenoid valves and pump must be checked with the help of the corresponding test steps of the diagnosis manual or the Diagnosis Assistance System (DAS).

Testing and repair work 

• All operations which concern the electronic accelerator (EFP) are described in the group 07 (ME-SFI, Engine control monolith, common rail diesel injection).
