DERM Circuit Detail:

DESCRIPTION:

When there is a vehicle accident of sufficient magnitude to set Code 51, the DERM stores accident information in the EEPROM. Code 52 is set when the EEPROM has stored 4 simultaneously closed arming and discriminating sensor events (Code 51 settings).

TEST CONDITION:

Tested every 100 milliseconds during "Continuous Monitoring".

FAILURE CONDITIONS:

Code 52 will set when the EEPROM area reserved for accident data in the DERM is detected to be full during "Continuous Monitoring" for 100 milliseconds.

CONDITIONS TO CLEAR:

This code cannot be cleared.

ACTION TAKEN:

"INFLATABLE RESTRAINT" indicator is turned on during all future Ignition cycles.
