(7) Measure the voltage between C-37 harness side connector
terminals 5 and 6 <1st squib> or 9 and 10 <2nd squib> and
body ground.
Voltage should measure 0 volt.
Q: Is the measured voltage within the specified range?
YES : Erase the diagnostic trouble code memory, and check
the diagnostic trouble code. If DTC B1B01 <1st
squib> or B1B05 <2nd squib> sets, replace the
SRS-ECU (Refer to
P.52B-383
). Then go to Step 7.
NO : Go to Step 6.
STEP 6. Check the harness for short circuit to power
supply between SRS-ECU connector C-37 (terminal No.5
and 6 <1st squib> or terminal No.9 and 10 <2nd squib>)
and clock spring connector C-208 (terminal No.4 and 3
<1st squib> or terminal No. 1 and 2 <2nd squib>).
Q: Are harness wires between the SRS-ECU connector
C-37 (terminal No.5 and 6 <1st squib> or terminal No.9
and 10 <2nd squib>) and clock spring connector C-208
(terminal No.4 and 3 <1st squib> or terminal No. 1 and 2
<2nd squib>) in good condition?
YES : Go to Step 7.
NO : Replace the harness wires between SRS-ECU
connector C-37 and clock spring connector C-208.
Then go to Step 7.
STEP 7. Recheck for diagnostic trouble code.
Check again if the DTC is set.
(1) Erase the DTC.
(2) Turn the ignition switch to the "ON" position.
(3) Check if the DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC B1B01 <1st squib> or B1B05 <2nd squib> set?
YES : Return to Step 1.
NO : The procedure is complete.
