Test K: Driver Air Bag Low Resistance (DTC B1934): Description

Electronic Crash Sensor (ECS) module monitors resistance of driver-side air bag ignitor by measuring resistance between ECS module connector terminals No. 1 (Light Green wire, circuit No. 941) and No. 15 (Blue wire, circuit No. 942). If ECS module detects low resistance between these terminals, it will store Diagnostic Trouble Code (DTC) B1934 in memory and flash Code 34 on AIR BAG warning light.
