051352 DIGNOSTICS DTC 1152/28 PSSEER IRG ON/OFF INDICTOR LIGHT CIRCUIT MLFUNCTION 05IVQ02 CIRCUIT DESCRIPTION The passenger airbag ON/OFF indicator light circuit consists of the airbag sensor assy center and the telltale lamp assy (passenger airbag ON/OFF indicator). This circuit indicates the operation condition of the front passenger airbag assy and the front seat airbag assy RH and passenger side seat belt pretensioner. DTC 1152/28 is recorded when a malfunction is detected in the passenger airbag ON/OFF indicator light circuit. DTC No. DTC Detecting Condition Trouble rea 1152/28 When the airbag sensor assy center receives a line short signal, open signal, short to ground signal or + short signal in the passenger airbag ON/OFF indicator light circuit for 2 seconds. lamp assy malfunction sensor assy center malfunction lamp (Passenger airbag ON/OFF indicator) sensor assy center Cowl wire 1542

051354 INSPECTION PROCEDURE DIGNOSTICS 1 CHECK PSSEER IRG ON/OFF INDICTOR LIGHT OPERTION Turn the ignition switch to the ON position. (b) Check the passenger airbag ON/OFF indicator light operation. HINT: Refer to the normal condition of the passenger airbag ON/OFF indicator light (see page 051207 ). C Ignition Switch Passenger ON/OFF Indicator Light ( ON ) Passenger ON/OFF Indicator Light ( OFF ) ON OFF ON OFF ON OFF 4 sec. 2 sec. 4 sec. 2 sec. ON/OFF condition depends on the front passenger detection results. H43700 Result: : During period in the illustration, even if both the ON and OFF passenger airbag ON/OFF indicator lights normally come on, both of them do not go off during period. During periods and in the illustration, even if both the ON and OFF passenger airbag ON/OFF indicator lights normally come on, both of them come on during period C. : During period, neither the ON nor OFF passenger airbag ON/OFF indicator lights come on, or one of them does not come on. During period C, even if the front passenger seat is occupied, neither the ON nor OFF passenger airbag ON/OFF indicator lights come on. Go to step 6 1544
