Front Passenger Side Seat Belt Warning Light Malfunction
SEAT BELT: SEAT BELT WARNING SYSTEM: Front Passenger Side Seat Belt Warning Light Malfunction
Front Passenger Side Seat Belt Warning Light Malfunction
DESCRIPTION
When the ignition switch is ON and the front passenger seat is occupied, the occupant classification ECU communicates the status of the front seat inner belt assembly (passenger side) to the center airbag sensor assembly. The combination meter assembly receives signals from the center airbag sensor assembly and transmits them to the integration control and panel assembly. When the seat belt is unfastened, the combination meter assembly flashes the front passenger seat belt warning light on the integration control and panel assembly. When the seat belt is fastened, the combination meter assembly stops flashing the front passenger seat belt warning light on the integration control and panel assembly.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK SUPPLEMENTAL RESTRAINT SYSTEM
(a) Connect a Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Body Electrical / SRS Airbag / Trouble Codes.
Result:
B -- GO TO SUPPLEMENTAL RESTRAINT SYSTEM
A -- Continue to next step.
2. CHECK OCCUPANT CLASSIFICATION SYSTEM
(a) Connect a Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Body Electrical / Occupant Detect / Trouble Codes.
Result:
B -- GO TO OCCUPANT CLASSIFICATION SYSTEM
A -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (CENTER AIRBAG SENSOR ASSEMBLY - COMBINATION METER ASSEMBLY)
(a) Disconnect the E29 center airbag sensor assembly connector.
(b) Disconnect the E13 combination meter assembly connector.
(c) Measure the resistance.
Standard resistance:
(d) Reconnect the center airbag sensor assembly connector.
(e) Reconnect the combination meter assembly connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - AIR CONDITIONING AMPLIFIER)
(a) Disconnect the E13 combination meter assembly connector.
(b) Disconnect the E32 air conditioning amplifier connector.
(c) Measure the resistance.
Standard resistance:
(d) Reconnect the combination meter assembly connector.
(e) Reconnect the air conditioning amplifier connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. INSPECT COMBINATION METER ASSEMBLY
(a) Measure the voltage.
Standard voltage:
NG -- REPLACE COMBINATION METER ASSEMBLY
OK -- REPLACE INTEGRATION CONTROL AND PANEL ASSEMBLY
