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 the 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 the 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.
