Model All model
Group Restraints(81)
Number KT2008090301

Area N.America
Subject Air Bag Code B2500
- Description
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.
