Air Bag Code B2500
KMA has found in some cases that Airbag Control Modules (ACM's) have been replaced for DTC B2500. B2500 sets when there are faults in the airbag
warning lamp circuit. This code may also set by lower then normal battery voltage, such is the case of a dead or discharged battery.
When investigating DTC B2500, before diagnosing the airbag warning circuit, first check if the battery voltage had dropped in sequence with code
B2500 being set. Ask the customer if the vehicle had been jumped started, or check if the battery had been replaced recently. If battery voltage was or is
not the concern, then check the airbag warning lamp circuit throughly.
