Testing Testing DAS (Immobilizer) Systems

capacitive sensors. The 2nd generation Keyless Go no longer uses a separate chip card but has

the Keyless Go chip card integrated into the remote key housing.

Note the following with the Keyless Go:

• Some Keyless Go vehicles may not have any emergency key door access. In the case of a

dead battery, the emergency key can be used to open trunk to access battery, which can

then be charged. The remote key is then used to open the doors.

All DAS Versions

Note the following when testing DAS systems:

• DAS or RCL module replacement means that all of the remote transmitters and transponder

keys must be synchronized and version-coded using the factory scan tool.

• The ME control module and either the EIS (DAS 3) or DAS control module are electronically

permanently married to each other after 40 engine starts. There is no factory procedure to

undo this. This means that a used engine, EIS or DAS control unit cannot be used on

another vehicle. A new control unit can be installed for testing provided the 40 engine starts

are not exceeded. Note that the new control unit must be variant coded before it can be

used. Technicians have reported successfully resetting the counter to 0 on a test ECU at

about count 20 by removing the version coding and ECU power for 10 to 30 minutes.
