WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
- HINT:
- Operating the engine switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
1.DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the CAN main wire and the CAN branch wire.
- CAUTION:
- Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the airbag system.
- NOTICE:
- After turning the engine switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work (LandCruiser RM000003YMD00TX.html).
- When disconnecting the cable, some systems need to be initialized after the cable is reconnected (LandCruiser RM000003YMF011X.html).
2.CHECK FOR OPEN IN CAN BUS WIRE (STEERING ANGLE SENSOR CAN BRANCH WIRE) |
Disconnect the G33 spiral cable sub-assembly (steering angle sensor) connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Switch Condition
| Specified Condition
|
G33-4 (CANH) - G33-3 (CANL)
| Engine switch off
| 54 to 69 Ω

3.CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - BATTERY AND BODY GROUND) |
Connect the cable to the negative (-) battery terminal.
- NOTICE:
- When disconnecting the cable, some systems need to be initialized after the cable is reconnected (LandCruiser RM000003YMF011X.html).
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
G33-2 (ESS) - Body ground
| Always
| Below 1 Ω
|
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection
| Condition
| Specified Condition
|
G33-6 (BAT) - Body ground
| Always
| 11 to 14 V
|
G33-5 (IG) - Body ground
| Engine switch on (IG)
| 11 to 14 V
