DIAGNOSIS CODE SET CONDITIONS These diagnosis codes are set when a fault is detected in the SRS-ECU. The most likely causes for this code to be set are shown in the table below:
Code No. | Part/Circuit integral to SRS-ECU | Trouble causes
--- | --- | ---
14 | Analog G-sensor | When the analog G-sensor is not operating When the characteristics of the analog G-sensor are abnormal When the output from the analog G-sensor is abnormal
15 | Safing G-sensor (front air bag) | Short circuit in the safing G-sensor
16 | Open circuit in the safing G-sensor
17 | Safing G-sensor (side air bag) | When the safing G-sensor is not operating When the characteristics of the safing G-sensor are abnormal When the output from the safing G-sensor is abnormal
31 | Capacitor | Voltage at the capacitor terminal is higher than the specified value for five seconds or more
32 | Voltage at the capacitor terminal is lower than the specified value for five seconds or more (This is not detected if diagnosis code No.41 or 42 indicating battery positive voltage drop has been output).
45 | Non-volatile memory (EEPROM) and A/D converter | When the non-volatile memory (EEPROM) and A/D converter system are abnormal
51 | Driver's air bag module (squib ignition drive circuit) | Short circuit in the squib ignition drive circuit
52 | Open circuit in the squib ignition drive circuit
54 | Front passenger's air bag module (squib ignition drive circuit) | Short circuit in the squib ignition drive circuit
55 | Open circuit in the squib ignition drive circuit
56 | Driver’s seat belt pre-tensioner (squib ignition drive circuit) | Short circuit in the squib ignition drive circuit
57 | Open circuit in the squib ignition drive circuit
58 | Passenger’s seat belt pre-tensioner (squib ignition drive circuit) | Short circuit in the squib ignition drive circuit
59 | Open circuit in the squib ignition drive circuit
73 | Side air bag module (RH) (squib ignition drive circuit) | Short circuit in the squib ignition drive circuit
74 | Open circuit in the squib ignition drive circuit
83 | Side air bag module (LH) (squib ignition drive circuit) | Short circuit in the squib ignition drive circuit
