12. Measure the voltage between body ground and
SRS unit connector A (28P) terminals No. 16 and
No. 28, individually. There should be less than 0.2 V.
Go to step 13.
Short to power in the engine compartment
wire harness or dashboard wire harness; replace
the faulty harness, then clear the DTC.
13. Turn the ignition switch to LOCK (0).
14. Connect the SRS inflator simulator (jumper connector) and the black lead (A) of simulator
lead L to the engine compartment wire harness 2P
connector (B). 15. Measure the resistance between SRS unit
connector A (28P) terminals No. 16 and No. 28.
There should be less than 1.0 .
Faulty right front impact sensor or SRS unit;
replace the right front impact sensor (see page
24-210), then clear the DTC. If the problem is still
present, replace the SRS unit (see page 24-203).
Poor connection at C203, open in engine
compartment wire harness, or open in dashboard
wire harness. Inspect C203 (see page 22-22). If it is
OK, replace the faulty harness, then clear the
DTC.
