DTC 24: SYSTEM DISARM FAILURE OR INTERNAL DIAGNOSTIC MONITOR FAULT


Normal Operation

The air bag diagnostic monitor measures the voltage at Pins 2, 3, 4, 5, 23 and 24 of the air bag diagnostic monitor connector.

If the air bag diagnostic monitor measures low voltage on Pins 2, 3, 4, or 5 (or a voltage of less than 5 volts on Pins 23 or 24), the air bag diagnostic monitor will flash out a DTC 13 (or 14) on the air bag indicator to indicate a possible short to ground on these circuits
At the same time the air bag diagnostic monitor begins flashing out the DTC 13 or 14, it attempts to disarm the air bag system to prevent inadvertent deployment of the air bag(s) by blowing the 10A battery fuse feeding diagnostic monitor Pins 13 and 14. It attempts to blow the fuse by activating a solid state switch which shorts the battery feed at Pin 13 to sheet metal ground at the air bag diagnostic monitor's bracket.
The air bag diagnostic monitor will make up to three attempts to blow this fuse, spaced one minute apart.

If the air bag diagnostic monitor has blown the fuse and thus removed battery voltage at Pin 14, a DTC 12 will be stored
If the air bag diagnostic monitor attempts to blow the 10A battery fuse three times and fails each time, a DTC 24 will be stored.
After the 10A fuse is blown or three attempts to blow it fail, the air bag diagnostic monitor will not attempt to disarm again until the DTC 13 or 14 condition has been serviced and cleared.

The air bag diagnostic monitor also performs several on-board diagnostics every time the ignition switch is turned to RUN.

If any of these tests fail, the air bag diagnostic monitor will flash DTC 24.

If any of these conditions later resumes normal operation, the next ignition switch cycle will produce a DTC 64 (or a higher priority DTC if one exists).

Possible Causes

System disarm failure or internal diagnostic failure can be caused by:
An improper fuse value in the battery circuit feeding air bag diagnostic monitor Pins 13 and 14.

Excessive resistance or opens in the battery feed circuit due to corrosion, poor crimps, etc. The excess resistance could occur in the wiring at the air bag diagnostic monitor harness Pin 13, the 10A battery fuse terminal, or elsewhere in the battery feed circuit.

A vehicle charging system concern could prevent the air bag diagnostic monitor from drawing enough current to perform its disarm.

An internal air bag diagnostic monitor failure on on-board diagnostic or system disarm.

Resistance to ground in the normally open primary crash sensor feed circuits 617 (PK/O), 619 (PK/W), 624 (Y/W) and 625 (Y/LG).

Now that I have you thoughly confused if you need schematics and the pin point test give me your email and I'll send them to you.
