Control Module, Separating From Hydraulic Unit
Special tools and workshop equipment required
- ESD Work Surface:VAS6613
- TORX® insert T25
- If the control module is faulty, then the control module is to be separated from the hydraulic unit and only the control module replaced.
- If the hydraulic unit is faulty, the hydraulic unit and the control module are to be replaced together.
- The ESP unit must be removed in order to separate the control module and the hydraulic unit.
- Never separate the return flow pump from the hydraulic unit.
- Discharge electrostatic charge: touch the electro-static discharge work surface
- Protect the inner control module from moisture and dirt.
-- Touch a grounded object before working on electrical equipment :VAS6613 . Do not touch the connector terminals or electronic components directly.
-- Position the hydraulic unit with the control module on the :VAS6613 .
-- Remove the three TORX® bolts from the control module and set aside immediately (risk of confusing them new TORX® bolts).
-- Position the hydraulic unit with the control module from upward on the :VAS6613 .
-- Pull the control module off from hydraulic unit without tilting.
-- Cover control module magnetic coils with a lint free cloth.
-- Check the cleanliness of the hydraulic unit sealing surface if necessary clean with mineral spirits and a lint-free cloth.
The hydraulic unit sealing surface must not be worked with a file, metal scraper, sand paper or similar.
If the hydraulic unit sealing surface is damaged (for example through grooves or scrapes) the hydraulic unit must be replaced with the control module.
The seal on the control module must not be pulled out or raised up.
The seal on the control module cannot be replaced.
