Circuit Description
WARNING: This page is about a different car, the 1998 Cadillac Seville. However, it is still accessible from the selected car via links, so may be relevant.
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.
