DTC B1007

DTC Descriptor
DTC B1007
- EEPROM Write Error

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

Circuit/System Description

As part of normal data processing, the module performs a data programming check. The module writes information to a data block in the electrically erasable read only memory (EEPROM). The module then reads the data and compares it to what was sent to the data block. The EEPROM write error detection is handled inside the control module. No external circuits are involved.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

Data does not match after 3 consecutive attempts.

Action Taken When the DTC Sets

The module writes to another area of the EEPROM, this becomes the new permanent area to store the data. The data location is allowed to change until all of the available EEPROM is used.

Conditions for Clearing the DTC

* A current DTC clears when the malfunction is no longer present.
* A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.

Circuit/System Verification

Verify that DTC B1007 is not set.

If the DTC is set as current, replace the control module.
