ZCS Stored Location In Vehicle

2001 BMW 530i AutomaticSECTION ZCS Stored Location In Vehicle

The ZCS is stored in the vehicle to simplify the coding procedures when a module needs to be recoded or a replacement module needs to be coded. Depending on the vehicle, the ZCS information is stored in the following locations:

ZCS STORED LOCATION IN VEHICLE

Vehicle Model Module Vehicle Model Module
E31 All EKM E39 All Instrument Cluster/EWS
E32 All Instrument Cluster E38 All Instrument Cluster/EWS
E34 All Instrument Cluster E46(1) All Instrument Cluster/LSZ
E36 318i/is 325i/is M3 Instrument Cluster E52 All Instrument Cluster/LSZ
E36 318ti Z3 EWS II As of 9/98: Instrument Cluster/EWS E53 All Instument Cluster/LSZ
(1) The E46 switched to a Vehicle Order (VO) data structure in 9/01.

The procedure to code control modules that utilize the ZCS information can be performed via the DISplus/GT1 or SSS using Progman with CIP 15.0 or higher and accessing the "Codierung ZCS/FA" function.

When coding a ZCS codable control module the coding program in CIP automatically searches the stored location, based on the VIN, and codes the selected module according to the information provided in the ZCS code.

On later production vehicles the ZCS information began to be stored in two locations, referred to as redundant data storages, this insures that the information is always available in the event the primary device storing the data fails.

NOTE: On early production vehicles without redundant data storage, if the module being coded or recoded is the module that stores the ZCS information, then the vehicles ZCS information must be obtained from the label located on the vehicle or electronically accessed from the module and printed out then entered manually via the input screen on DISplus/GT1 or SSS.

For vehicles with redundant data storage the coding of the module storing the data is performed automatically using the information stored in the "back up" module.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
