B1007 BCM Internal Memory Malfunction

DTC B1007 BCM Internal Memory Malfunction:

CIRCUIT DESCRIPTION
The module performs internal tests on the EEPROM each time the module performs a write function to a memory address in the EEPROM. The module reads back the data that has been written and compares it to the data it wrote.

CONDITIONS FOR SETTING DTC
^ The data read back after a write does not match the data being written after 3 consecutive times.
^ The condition must occur when data is being written.

ACTION TAKEN WHEN THE DTC SETS
^ The module stores a DTC B1007 as current.
^ No driver warning message is displayed for this DTC.
^ The module will store the value being written in another memory address in the EEPROM.

CONDITIONS FOR CLEARING DTC
^ This DTC requires a successful write in order to change from current to history.
^ The module no longer detects an internal write malfunction.
^ A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.

DIAGNOSTIC AIDS
Since the EEPROM cannot be removed from the module and DTC B1007 is an internal module malfunction, the module may need to be replaced.
