9.3.6.3 Front Passenger Seat Belt Warning Lamp Malfunction

Circuit diagram:

Refer to 9.3.6.2 Circuit Diagram of Driver Seat Belt Warning Lamp Not Working.

Diagnostic Steps:

1

Inspect passenger seat safety belt buckle assembly.

(a) Disconnect passenger seat safety belt buckle wire

harness connector SO07.

(b) Use multimeter to measure whether passenger's

side seat safety belt switch status meets the
following requirements.

(c) Disconnect safety belt, and resistance between

terminal 1 and 2 is lower than 1Ω.

(d) When tie safety belt, resistance between terminal

1 and 2 is 10kΩ or higher.

Confirm if the resistance conforms to standard value.

Inspect the communication between the passenger seat safety belt buckle assembly and the grounding.

(a) Disconnect passenger seat safety belt buckle wire harness connector SO07.

(b) Measure passenger seat safety belt buckle wire harness connector SO07 terminal 1 and vehicle body

grounding.

Standard Resistance: Less than 1 Ω

Confirm if the resistance conforms to standard value.

3

Inspect passenger detection sensor.

(a) Disconnect passenger seat sensor connector SO03.

(b) Use multimeter to measure resistance of sensor according to the following condition.

(c) Passenger seat was took up , resistance is low than 100 Ω

(d) When passenger seat isn't occupied, resistance will be 10kΩ or higher.

Confirm if the resistance conforms to standard value.

Inspect whether the passenger seat has communication between the manned sensor and passenger seat
safety belt buckle.

(a) Disconnect passenger detection sensor wire

harness connector SO03.

(b) Disconnect passenger seat safety belt latch

harness connector SO07.

(c) Use multimeter to measure resistance between

passenger seat detection sensor wire harness
connector SO03 terminal 2 and passenger seat
safety belt buckle wire harness connector SO07
terminal 2.

Standard resistant value :is less than 1Ω

Confirm if the resistance conforms to standard value.
