10. Measure the resistance between left side impact
sensor (second) 2P connector terminals No. 1 and
No. 2. There should be an open circuit or at least
1M .
Go to step 11.
Short in the floor wire harness; replace the
floor wire harness, then clear the DTC.
11. Measure the resistance between body ground and left side impact sensor (second) 2P connector
terminals No. 1 and No. 2, individually. There
should be an open circuit or at least 1 M .
Go to step 12.
Short to ground in the floor wire harness;
replace the floor wire harness, then clear the
DTC. 12. Reconnect the negative cable to the battery.
13. Turn the ignition switch to ON (II).
14. Measure the voltage between body ground and left
side impact sensor (second) 2P connector terminals
No. 1 and No. 2, individually. There should be less
than 0.2 V.
Go to step 15.
Short to power in the floor wire harness;
replace the floor wire harness, then clear the
DTC.
15. Turn the ignition switch to LOCK (0).
16. Connect the SRS inflator simulator (jumper connector) and the red lead (A) of simulator lead L
to the floor wire harness 4P connector (B).
