Incorrect service info?
Here's the service info for installing the airbag control module. Thoughts?
- To install, perform the steps used for removal in reverse order.
- Switch on ignition.
- Make sure that no persons are in the vehicle.
- Connect battery.
- If the control unit was replaced, it must be coded..."
Yeah, I wasn't even thinking of that step, but considering that the battery is under the driver seat, then someone is going to have to at least reach inside the vehicle to connect the battery. The main issue I was concerned with, in case it isn't clear to anyone reading it, is that the directions state to "Switch on ignition" then "Connect battery". Those crazy Germans have some wild ideas or…
There is no way to switch on ignition without connecting battery. So I think steps are mixed up
Steve - i checked both ProDemand and OE service information they both state what you posted..... It seems strange to me as well but it may be correct. I do have a vague memory of another car line (i think it was a Chrysler product i was doing air bag work on) saying to have key on when reconnecting the battery
Interesting. This could be a valid procedure then. If so, I wonder what the reasoning is behind it.
Thanks to Bill Kenel for mentioning a similar procedure for Chrysler cars. I looked up a 2005 Chrysler 300 3.5L, and found this under airbag system testing... "AIRBAG SYSTEM - With the battery negative cable disconnected, connect the scan tool to the Data Link Connector (DLC). - Turn the ignition key to the ON position, then exit vehicle with the scan tool. - After checking that no one is…
In a training class we were told that the arcing at the battery was less dangerous then an unintended deployment, not sure if that was a Ford Official stance or just the instructors. Either way they want the system powered up without a tech reaching across the Driver's airbag Previous systems showed installing fuses or connecting battery after the key was on like this 05 Explorer: Repowering…
Ok, so if I'm understanding this right, the airbags could accidentally deploy on power up, either by turning the key on or by connecting the battery, so they would rather have you put the key on first then connect the battery, that way at least you aren't next to the airbags if they deploy. Now I get it. Thanks.
Only problem with that is there is a chance the battery could explode from the arc. Not likely, but possible. Safety first. Your right. It does seem a little strange they suggest doing it this the way.
Hi Steve, Agree with other posts regarding the liability reasons for what seems like a typo in the order of operations. It’s prudent to ask though. Typos are rampant everywhere today. USA Today couldn’t even catch a typo in their top headline - misspelling the word Technology in an ADAS article. Lawyers for the OEMs often lack common sense and service manuals are often wrong from the OEM. OEM…
Trying to decipher service information on these German vehicles is half the job, and yes, they do have typos and confusing translations and just plain incorrect information at times. I'm glad I asked about this particular piece of info because I figured it was wrong, but now I know it is actually correct. �
That's what I would do. I would think you would risk more of a chance of a bag deployment having the key on and then turning on the ignition switch. Oh well, what do I know?
