DTC B276A Short to GND in Tilt Sensor Signal Circuit

DESCRIPTION

The yaw rate sensor conducts a self-diagnosis immediately after power is supplied to the sensor (when the theft deterrent system is set).

This DTC is stored when terminal CSIF of the yaw rate sensor has not received a signal for 5 seconds or more.

DTC Code	DTC Detection Condition	Trouble Area
B276A	After normal/trouble signal is output from the yaw rate sensor as result of self-diagnosis, the following malfunction is detected: Terminal CSIF of the yaw rate sensor has not received signal for 5 seconds or more	Yaw rate sensor Certification ECU (Smart key ECU assembly) Harness or connector

Dtc B276A Short To Gnd In Tilt Sensor Signal Circuit. THEFT DETERRENT / KEYLESS ENTRY. Land Cruiser URJ200 URJ202 GRJ200 VDJ200

1.CHECK HARNESS OR 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

NG

REPAIR OR REPLACE HARNESS OR CONNECTOR

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.

NG

REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

OK

END (YAW RATE SENSOR IS FAULTY)
