The ignition voltage is between 11-18 volts.To determine if the I/M readiness diagnostic tests can be run during this ignition cycle, use a scan tool to observe the I/M monitor-enabled parameters in the I/M Data List. Perform the Inspection/Maintenance (I/M) Complete System Set Procedure if any I/M System Status indicators are set to NO. When all I/M monitored diagnostic tests are completed, the I/M System Status indicators are set to YES. The purpose of the Inspection/Maintenance (I/M) complete system set procedure is to satisfy the enable criteria necessary to execute all of the I/M readiness diagnostics and complete the drive cycles for those particular diagnostics. Diagnostic Procedure Instructions provide an overview of each diagnostic category.Review Strategy Based Diagnosis for an overview of the diagnostic approach.Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.Inspection/Maintenance (I/M) Complete System Set Procedure It can take several cold soak drive cycles AND a tank of gas to set at times just due to all the complicated parameters that have to be set in order for the monitor to transition from NOT READY to READY The GM EVAP monitor procedure is a known trouble spot for all GM vehicles (regardless of any tunes or the AFM Disabler being installed). I hear people drive 1000's of km or miles and still do not get this stupid thing to switch to "complete". I did that specifically at night, when the highway is empty, as this requires highway driving.ĭoes anyone have any idea how to make this stupid EVAP monitor switch to "completed"? Or, perhaps, someone has a '08 Enclave-specific drive cycle procedure since I could not find it? I tried at least 3 different driving cycles I could find online for GM vehicles to get this bugger to switch to "Complete" or "Ready," just to fail every time. This sucker stays "incomplete" no matter what I do. With one exception, it has been a week of driving, and every monitor came back as "completed" within a day, with the exception of the EVAP monitor. With the exception of ONE thing: I need to do an emission test on my '08 Enclave, and after resetting the computer, all of the emission monitors went into an "incomplete" state. Currently, no codes are recorded, and everything seems to be okay. I had some repairs done to my vehicle, and the technician reset the codes. Would I now be able to pass with those codes simply not supported? Or does not supported pretty much mean not ready.Perhaps anyone can help me. I never would've gotten this tune if I knew it would create all these problems, I have smog due in 3 weeks and I'm completely panicking as I'm a noob to all of this stuff. I assume the stock cat fixed this problem as it was related to the HFC? And even if it wasn't fixed the check engine light would've come back when I reverted to stock tune? Could this have anything to do with my smog problems? I had the car tuned by Jeff Evans, at one point I had the P0139 check engine code, but Jeff told me it was purely related to the high flow cat and the secondary o2 and there was no problem so we disabled the light. So I have no monitors not ready and hondata isn't able to give me the info on them, or am I still screwed? However these things don't say not ready on Hondata, they just say "not supported." (photo attached). Everything is supported and ready besides Heated catalyst, secondary air system, a/c system, and EGR system. Over the next 3 days I drove about 145 miles through various conditions, mostly (45-50 mph stop and go, and 55-60 mph highway cruising, and maybe 30 miles of 70-75 mph highway cruising) I decided before going back I should check what my flashpro says about this and it seems as if things might still not be good. He told me to drive the car 100 miles and come back. I get the car tested and everything passes besides my Evaporative and Catalyst monitors being "not ready." The smog guy was nice about it, told me this happens when ecu/battery is replaced or reset. In preparation of this I removed my berk hfc and replaced with oem, and I reverted my Hondata tune to stock (not stock equivalent calibration, but as in I clicked the revert to stock button.) So I think I'm beyond ready as I now only have my HKS catback and a carb legal K&N intake. So after owning the s2000 for about a year a half I get the joy of taking care of smog in California.
