WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
PROCEDURE
1. |
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and branch wire.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable
is reconnected (See page ).
|
2. |
CHECK FOR OPEN IN CAN BUS WIRE (YAW RATE SENSOR ASSEMBLY BRANCH WIRE) |
(a) Disconnect the F36 yaw rate sensor assembly connector. |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connector |
Switch Condition |
Specified Condition |
---|---|---|
F36-3 (CANH) - F36-2 (CANL) |
Ignition switch off |
54 to 69 Ω |

REPAIR OR REPLACE YAW RATE SENSOR ASSEMBLY BRANCH WIRE OR CONNECTOR (CANH, CANL) |
|
3. |
CHECK HARNESS AND CONNECTOR (YAW RATE SENSOR ASSEMBLY - BATTERY AND BODY GROUND) |
(a) Connect the cable to the negative (-) battery terminal. NOTICE: When disconnecting the cable, some systems need to be initialized after
the cable is reconnected (See page |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |
Condition |
Specified Condition |
---|---|---|
F36-1 (GND) - Body ground |
Always |
Below 1 Ω |
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection |
Switch Condition |
Specified Condition |
---|---|---|
F36-4 (IG) - Body ground |
Ignition switch ON |
11 to 14 V |

Rear Airbag Sensor RH Circuit Malfunction (B1630/23,B1635/24)
DESCRIPTION
The rear airbag sensor consists of the safing sensor, diagnostic circuit,
lateral deceleration sensor, etc.
If the center airbag sensor receives signals from the lateral deceleration
sensor, it determines whether the SRS should ...
