Q: Are the harness wires between SRS-ECU connector
C-36 (terminal No.33 and 34) and side-air bag module
(RH) connector D-36 (terminal No.1 and 2) in good
condition?
YES : Go to Step 6.
NO : Replace the harness wires between SRS-ECU
connector C-36 and side-air bag module (RH)
connector D-36. Then go to Step 6.
STEP 6. Recheck for diagnostic trouble code.
Check again if the DTC is set.
