1 IGNOSTICS SUPPLMNTL RSTRINT SYSTM TC 1148/36 FRONT IRG SNSOR (RH) MLFUNCTION 05IVN01 CIRCUIT SCRIPTION The airbag front RH sensor circuit consists of the diagnostic circuit and the frontal deceleration sensor, etc. If the airbag sensor assy center receives signals from the frontal deceleration sensor, it judges whether or not the SRS should be activated. TC 1148/36 is recorded when a malfunction in the airbag front RH sensor is detected. TC No. TC etecting Condition Trouble rea 1148/36 Short circuit in front airbag sensor RH wire harness (to +) Short circuit in front airbag sensor RH wire harness (to ground) Open circuit in wire harness or SL wire harness of front airbag sensor RH front RH sensor malfunction sensor assy center malfunction front RH sensor sensor assy center Cowl wire ngine room main wire WIRI IGRM 9 RH 2 W 3 W RW H HIGHLNR RPIR MNUL (RM1144U) uthor : 1522
