DTC B1154/38 AIRBAG SENSOR REAR (RH)
MALFUNCTION
CIRCUIT DESCRIPTION
The airbag sensor rear RH consists of the safing sensor, the diagnostic circuit and the lateral deceleration
sensor, etc.
If the airbag sensor assy center receives signals from the lateral deceleration sensor, it judges whether or
not the SRS should be activated.
DTC B1154/38 is recorded when a malfunction is detected in the airbag sensor rear RH circuit.
DTC No. DTC Detecting Condition Trouble Area
S The airbag sensor assy center receives a line short circuit
signal, an open circuit signal, a short circuit to ground sig-
