Two displays this week highlighted how points with a battery can have an effect on collision restore diagnostic scanning.
Collision Recommendation CEO Mike Anderson instructed an April 28 Dave Luehr’s Elite Body Shop Academy webinar that about 20 p.c of automobiles want a totally new battery “earlier than you ever contact the automobile.”
A dying battery can result in diagnostic hassle codes thrown over misplaced communications with electronics, in response to Anderson.
“That share could possibly be even larger” if the store is situated someplace notably sizzling or chilly, Anderson mentioned.
Anderson didn’t cite the supply of the 20 p.c statistic. Nevertheless, one other collision restore video additionally just lately talked about the potential for a dud battery to seem and create a special headache for a physique store.
Society of Collision Restore Specialists board member Michael Bradshaw mentioned his store, Okay&M Collision, had instituted a normal working process of battery testing at consumption.
In any other case, the battery won’t be revealed as inadequate till a store makes an attempt to restart the automobile electrical system late within the restore, Bradshaw mentioned throughout an SCRS “Kool Tools” video posted earlier in April. The store should contact the shopper on the final minute and inform them a brand new battery is required.
“It simply creates quite a lot of chaos,” Bradshaw mentioned of such situations.
A day after Anderson’s feedback on the Luehr webinar, asTech OEM and business technical relations director Jake Rodenroth advocated utilizing a battery maintainer for automobile diagnostics.
Rodenroth described to an April 29 Collision Hub “World Fair” audience how a scan on a 2019 Nissan Sentra with out battery assist confirmed the battery operating at 9 volts.
Following software of a battery maintainer, the system confirmed 13.3 volts.
At 9 volts, “I used to be really lacking controllers” through the automobile scan, Rodenroth mentioned.
He mentioned automobiles are “good sufficient” in a lower-voltage state of affairs to close off controllers which weren’t germane to beginning the automobile. Methods like navigation and air-con are usually among the many first to be sacrificed by the automobile, he mentioned.
Rodenroth referred to as it a “diagnostics finest follow” to run battery assist.
“A bounce field isn’t battery assist,” Anderson cautioned through the Luehr webinar. He mentioned a trickle field additionally wouldn’t work.
Chris Arcudi, co-owner of Dents and Dings, requested through the Luehr webinar if battery assist could possibly be related to a automobile energy put up. Rodenroth, who additionally appeared in that broadcast, mentioned he personally felt it was higher to nonetheless use the battery.
“Numerous these automobiles, particularly automobiles with start-stop know-how, have battery load sensors on the optimistic cable,” Rodenroth mentioned.
He mentioned he felt that sticking to the supply could be higher than utilizing the bounce level.
“A bounce level wasn’t actually supposed to stabilize a automobile’s present,” Rodenroth mentioned.
