Front Passenger Side Seat Belt Warning Light Malfunction

METER: METER / GAUGE SYSTEM (for Hatchback): 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 center airbag sensor assembly communicates the status of the front seat inner belt assembly RH to the main body ECU using the CAN communication line. The main body ECU receives signals from the center airbag sensor assembly and transmits them to the combination meter assembly. When the front passenger seat belt is unfastened, the combination meter assembly flashes the front passenger seat belt warning light on the instrument panel finish panel end RH. When the seat belt is fastened, the combination meter assembly stops flashing the front passenger seat belt warning light on the instrument panel finish panel end RH.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK SUPPLEMENTAL RESTRAINT SYSTEM
(a) Connect the 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 the Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Body Electrical / Occupant Detection / Trouble Codes.
Result:






B -- GO TO OCCUPANT CLASSIFICATION SYSTEM
A -- Continue to next step.
3. READ VALUE USING TECHSTREAM (P BUCKLE SW)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Body Electrical / SRS Airbag / Data List.
Airbag ECU:






OK:
Front passenger seat belt warning light operates normally.
OK -- PERFORM ACTIVE TEST USING TECHSTREAM (P-BELT REMIND)
NG -- Continue to next step.
4. CHECK FRONT SEAT INNER BELT ASSEMBLY RH (PASSENGER SIDE)




(a) Disconnect the J11 front seat inner belt assembly RH (passenger side) connector.
(b) Measure the resistance.
Standard resistance:





(c) Reconnect the front seat belt inner assembly RH (passenger side) connector.
NG -- REPLACE FRONT SEAT INNER BELT ASSEMBLY RH (PASSENGER SIDE)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (ECU - FRONT SEAT INNER BELT ASSEMBLY RH (PASSENGER SIDE))




(a) Disconnect the J24 occupant classification ECU connector.
(b) Disconnect the J11 front seat inner belt connector (passenger side).
(c) Measure the resistance.
Standard resistance:





(d) Reconnect the occupant classification ECU connector.
(e) Reconnect the front seat inner belt connector (passenger side).
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (CENTER AIRBAG SENSOR ASSEMBLY - OCCUPANT CLASSIFICATION ECU)




(a) Disconnect the J9 center airbag sensor assembly connector.
(b) Disconnect the J24 occupant classification ECU connector.
(c) Measure the resistance.
Standard resistance:





(d) Reconnect the center airbag sensor assembly connector.
(e) Reconnect the occupant classification ECU connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE OCCUPANT CLASSIFICATION ECU
7. PERFORM ACTIVE TEST USING TECHSTREAM (P-BELT REMIND)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Body Electrical / Combination Meter / Active Test.
METER:






OK -- REPLACE COMBINATION METER ASSEMBLY
NG -- Continue to next step.
8. INSPECT FUSE
(a) Remove the GAUGE fuse from the main body ECU.
(b) Measure the resistance.
Standard resistance:
Below 1 Ohms
(c) Reinstall the GAUGE fuse.
NG -- REPLACE FUSE
OK -- Continue to next step.
9. INSPECT SEAT BELT WARNING LIGHT (PASSENGER SIDE)




(a) Remove the front passenger seat belt warning light.
(b) Disconnect the D27 front passenger seat belt warning light connector.
(c) Measure the resistance.
Standard resistance:





(d) Reconnect the front passenger seat belt warning light connector.
(e) Reinstall the front passenger seat belt warning light.
NG -- REPLACE SEAT BELT WARNING LIGHT (PASSENGER SIDE)
OK -- Continue to next step.
10. CHECK HARNESS AND CONNECTOR (FUSE - SEAT BELT WARNING LIGHT)




(a) Disconnect the D27 front passenger seat belt warning light connector.
(b) Disconnect the 4S main body ECU front side connector.
(c) Measure the resistance.
Standard resistance:





(d) Reconnect the front passenger seat belt warning light connector.
(e) Reconnect the main body ECU front side connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
11. CHECK HARNESS AND CONNECTOR (SEAT BELT WARNING LIGHT - COMBINATION METER ASSEMBLY)




(a) Disconnect the D2 combination meter assembly connector.
(b) Disconnect the D27 front passenger seat belt warning light connector.
(c) Measure the resistance.
Standard resistance:





(d) Reconnect the combination meter assembly connector.
(e) Reconnect the front passenger seat belt warning light connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE MAIN BODY ECU
