B1007
CIRCUIT DESCRIPTIONThe EEPROM write error detection is handled inside the control module. No external circuits are involved.
CONDITIONS FOR RUNNING THE DTC
The microprocessor runs the program to detect a write error whenever it writes to the EEPROM. The only requirements are voltage and ground. This program runs even if the voltage is out of the valid operating range.
ACTION TAKEN WHEN THE DTC SETS
The microprocessor tries to write to the memory location 3 times, if the write is not accomplished the code is set.
CONDITIONS FOR CLEARING THE DTC
The DTC clears when the microprocessor makes a successful write to the EEPROM.
DIAGNOSTIC AIDS
^ This DTC may be stored as a history DTC with out affecting the operation of the module. If stored only as a history DTC and not retrieved as a current DTC, do not replace the module.
^ If this DTC is retrieved as both a current and history DTC, replace the module.
