Help us help you. By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms (no start, high idle, misfire etc.) Along with any prevalent Diagnostic Trouble Codes, aka DTCs, other forum members will be able to help you get to a solution more quickly and easily!
Im trying to help a friend with his 2006 Honda Acura TL. he has no drivability problems by far as he drives this car to work. initial scan resulted to the following DCs
1) 61-01 (Battery Voltage failure)
2) 83-01 (ECM/PCM relation failure)
3) 86-01 (CAN relation failure)
4) 112-01 (internal power source)
i asked him to bring his car on the week end when he has no work.. i hv not check for battery voltage or connector looseness/corrosion or anything of that sort. but someone out there might have come acroos something similar to these DTCs and can share his/her experience with these codes...thank you in advance.
Did you get these out of the PCM, or ABS? CEL on? Because 83-1 is a fairly common code that only gets set in the ABS module. It's mostly a roadsign code, which almost always sets whenever there's a fault stored in the PCM. It sounds way worse than it is. :silly: Ignore it for now.
All the other codes could be set by low battery voltage, poor connections, whatever. TBH, all those codes sounds like symptoms of something else.
CEL, these were the current codes indicated; there were other DTCs, like :
1. 81-61 no signal from ODS unit
2. B1060, 1061 and 1831
it seems as if insufficient voltage at times is common to all. What I did was erased all and advised that when the CEL do come back to call me and only then will I check connectors, esp ABS module or even VSA, corrosion, etc. So far I have not gotten any calls yet.
I will update as soon as I get something...thanks.
Ok...i got a call from he owner. Although there are no DTCs present, the VSA light came on. Scanned and went live stream, though VSA switch indicated it was turning on and off, that VSA triangle light stayed on. There is brake fluid present and fuses seem ok though I will check the rest thoroughly...
Ohhhhh now I know what happened. :lol: The battery went low, and the VSA lost it's zero calibration. The loss of calibration will cause the VSA light to stay on with no codes stored. Why doesn't Honda have a code for loss of calibration (like Toyota)? Because that'd be too easy. :silly:
New Level Auto has a pretty cool video on this exact issue:
This may not be the case with your car, but I have run into more than one Honda/Acura that refused to turn off the triangle VSA lamp until the steering angle and occupancy detection sensor were recalibrated after repairs to the ABS system.
Sometimes even just replacing a wheel sensor will require the calibration procedure.
In the case of the ODS relearn, you will need a capable scan tool, and a weight of known value.
Even the dumbest guy in the shop can be used assuming he knows his weight and can sit reasonably still for a short period of time
I've seen his video earlier but unforunatel my Launch scanner does no have the neutral position memorizationtest. Would grounding pin#9 to pin#4 in BOB work as tried by some?
