STEP 17. Check the wiring harness between joint
connector (CAN1) C-105 and SRS-ECU connector C-37 for
a short to power supply. Measure the voltage at joint
connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the
voltage at the wiring harness side of joint connector
(CAN1).
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN1)
terminal 8 and body ground.
OK: 4.7 V or less
(4) Measure the voltage between joint connector (CAN1)
terminal 21 and body ground.
OK: 4.7 V or less
Q: Do all the voltages measure 4.7 V or less?
YES : Go to Step 18.
NO : Go to Step 51.
