Why airbag warning lights come on
Airbags no doubt save many lives and prevent serious injuries, but they have their faults that often need specialist knowledge to rectify.
One such common fault is an SRS warning light coming on for no apparent reason.
This happened recently to a neighbour’s car. His daughter had borrowed the car as hers was in for a service and he was none too pleased when she returned it with the light glowing.
Prime suspect is a poor connection at the seatbelt pre-tensioner. If side airbags are fitted, suspect the seat sensor connection.
Repeatedly fastening the seatbelt and/or adjusting the seat may eventually loosen connections and eventually bring loss of contact.
Rectification is a simple matter of cleaning and remaking the connections and mostly this may be done without activating the SRS. However, check with a specialist first.
As with most SRS work, it is recommended that the battery should be disconnected and left for at least half an hour before disconnecting anything else.
But do not forget to have the necessary security codes before disconnection.
Even allowing the battery to go flat might mean a trip to the franchised dealer to reset the light.
In the good old, bad old days, buying a cheapie was not so risky. We had contact-breaker ignition, braking systems (non-ABS) were easily understood and simple enough to service and electronic control units were virtually unheard of.
Now, repairing a faulty ABS could prove very expensive and even minor checks could hit your wallet.
For example, one guy who normally does his own servicing and repairs heard what he thought was a worn hub bearing. He jacked up the suspect side of the car and spun the wheel.
His mistake was to do this with the ignition on. This triggered the ABS warning light and he had to have it reset.
A needless expense, but he was right about the hub bearing though.
Some things on cars are still simple and easy to check.
Coolant hoses seem almost to last forever and consequently are often ignored until something goes wrong.
Bearing in mind what a sudden complete loss of coolant can do to an engine, regular inspection and squeezing of the hoses makes sense. In fact, I would recommend fitting new ones if a used car is bought or the hoses are more than a couple of years old.
