Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - THEFT DETERRENT / KEYLESS ENTRY
CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU [SMART KEY ECU ASSEMBLY] - YAW RATE SENSOR)
CHECK YAW RATE SENSOR (OPERATION)
DTC B2769 Tilt Sensor Signal Circuit Malfunction
DESCRIPTION
The yaw rate sensor conducts a self-diagnosis immediately after power is supplied to the sensor (when the theft deterrent system is set).
If a malfunction is detected in the CSIF-CSIF line, the certification ECU (smart key ECU assembly) stores this DTC.
| DTC Code | DTC Detection Condition | Trouble Area |
| B2769 | After a normal/trouble signal is output from the yaw rate sensor as the result of self-diagnosis, either of the following malfunctions is detected: The CSIF-CSIF line circuit is open. Reception of signals other than a normal/trouble signal. | Yaw rate sensor Certification ECU (Smart key ECU assembly) Harness or connector |
WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU [SMART KEY ECU ASSEMBLY] - YAW RATE SENSOR) |
Disconnect the E30 ECU connector.
Disconnect the E50 sensor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition E30-21 (CSIF) - E50-5 (CSIF) Always Below 1 Ω E30-21 (CSIF) or E50-5 (CSIF) - Body ground Always 10 kΩ or higher

| OK | |
| 2.CHECK YAW RATE SENSOR (OPERATION) |
Temporarily replace the yaw rate sensor that has a tilt determining function with a new or normally functioning one ().
Check that the system operates normally.
- OK:
- DTC B2769 is not output.
