CID 0820 FMI 02 Keypad Data Link Incorrect - Test
This diagnostic code is recorded when the VIMS main module determines that information on the Keypad data link is erratic or the data makes no sense. Check for loose connections of the Keypad data link. If this diagnostic code corresponds to the deactivation of any solenoids, then check for a failed diode assembly on the solenoid that was deactivated.
