Newer vehicles have a few installed options requiring constant battery voltage.

(6491 Views) Error Codes From Nissan Murano / Help Nissan Primera P11-144: Engine Not Starting Error Codes P0335 & P1336 / Error Codes P1519 And P1166 On Honda Accord (1) (2) (3) (4) (0) (Reply) (Go Down)Does Erasing Error Codes With The Scanner Solve The Initial Problem?? by lacasa: 9:37pm On Dec 22, 2012 Hello auto-gurus in da hse, Took my 2005 accord 4cyl for a general scan and the result came up with 6 error codes But, to my suprise the mechanic erased 3 out of 6 codes leaving 3 codes on the scanner. Then he said the remaining 3 error codes had to be attended to. Now, what i wanna кnoω is, does merely erasing a code solve the issue or ?.2ndly, after the scan was done and codes erased, the engine idle dropped soo low that the engine vibrates especially with the ac on.Any eplanation for this(Would appreciate yr replies, thanks.)Re: Does Erasing Error Codes With The Scanner Solve The Initial Problem?? by Denn(m): 6:36am On Dec 23, 2012 Codes are meant to indicate a possible malfunction in certain components or systems within a car. Some codes prop up because certain events did not happen in the recommended sequence. For example if during the repair of a door, one of the airbag wires was removed with the battery not properly disconnected, the airbag warning light will stay on even if the wires were coupled back. The only way to remove the light is to scan and erase such code. That doesn't imply that if there is a real airbag fault, erasing codes will magically repair the airbagThe diagnostic guy shld have listed out the codes both cleared and uncleared and proffered possible solutions. ThanksE&OERe: Does Erasing Error Codes With The Scanner Solve The Initial Problem?? by lacasa: 7:21am On Dec 23, 2012 Thanks Denn for µя comment.As u said, the codes were spelt out and i think about 3 sensors Were malfunctioning, (though, i dnt ave them wt me ryt nw).Ranging from 02sensor bank 1 to etc (will get the codes posted ltr on). But, wat angered me was why a simple scan would tamper with the engine's idle
