hello I',m an M.B. tech. These becker radios can be difficult if the wrong code is entered( i believe 3 times ina row) and go into security lock. if you enter code and it does not work remove radio and get serial number of and call dealer. The way you enter 4 digit code is by entering the number with the station program keys on the top of the face plate . then after code is entered you press the * symbol and it should start working. There is a becker web site that can also assist you with radio problems it is www.beckerautosound.com . good luck

If your lucky the dealer may still have it or the code may be written down at the back pages of your manual. The other place where you can get the code would be www.radio-code.com. before you try any of that, try 0000 to unlock your radio. Good luck and hope this helps.

DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the
The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage is higher or lower than required, DTC P0641 will set.
Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the 5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails. The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. A current DTC, Last Test Failed, clears when the diagnostic runs and passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.
Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.
Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.
