Circuit Description

The Rear Integration Module (RIM) performs internal tests on EEPROM each time the module performs a write function to a memory address in EEPROM. Module reads back data that has been written and compares it to the data. If data does not match after 3 consecutive write and verify attempts, module will indicate a write malfunction is current.

Conditions for setting DTC:

• Data read back after a write does not match data being written 3 consecutive times.
• Module detects an internal write malfunction.
• Conditions must occur when data is being written.
