Jim Grant's Tech Tips
'96 Honda Civic,
Air Bag Warning
Q:
Recently I removed the steering wheel on my daughter’s ‘96 Civic
to repair the turn signal cancel cam. I am certain that everything is
back together correctly and all connections are good. The problem is the
SIR light stays on. Disconnecting the battery does not reset the SIR computer.
How do I clear the codes in the SIR computer.
A:
The Supplemental Inflatable Restraint (SIR), in other words Air Bag warning
light is telling you that there is a system problem. If you happen to
turn the ignition on while the driver’s side air bag was removed
the SIR computer would have quickly noticed that the air bag was missing
and set a diagnostic trouble code. This would result in the SIR warning
light coming on. Unlike other computer systems that lose all their memory
when the battery is disconnected, the SIR’s computer on your Honda
does not forget. To turn the SIR warning light off will require a computer
scan tool or special tool to connect to the memory erase connector. You
do want to know why the warning light is on; it may have nothing to do
with your work, there may be a system problem. Have your vehicle checked
at a repair facility to be sure your air bag system is operating safely.
