SEAT BELT WARNING SYSTEM

Seat Belt Buckle Switch and Seat Pressure Switch CheckEHS000GX
1. CHECK TIME CONTROL UNIT INPUT SIGNAL
1. Turn ignition switch “ON”.
2. Check voltage between time control unit connector M31 terminal
22 (G/OR) and ground.
NOTE:
When performing the following procedure, a person is sitting on the
passenger side seat. (As a result, the seat pressure sensor is turned
ON.)
OK or NG
OK >> Seat belt buckle switch (passenger side) is OK.
NG >> GO TO 2.
2. CHECK SEAT BELT BACKLE SWITCH CIRCUIT HARNESS CONTINUITY
1. Turn ignition switch “OFF”.
2. Disconnect time control unit connector and seat belt buckle
switch (passenger side) connector.
3. Check the following.
with power seat
–Check continuity between time control unit connector M31 termi-
nal 22 (G/OR) and seat belt buckle switch (passenger side) con-
nector B352 terminal 13 (R).
–Check continuity between time control unit connector M31 termi-
nal 22 (G/OR) and ground.
without power seat
–Check continuity between time control unit connector M31 termi-
nal 22 (G/OR) and seat belt buckle switch (passenger side) con-
nector B113 terminal 1 (G/OR).
–Check continuity between time control unit connector M31 termi-
nal 22 (G/OR) and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness between time control unit and seat belt buckle switch.
