Removethe positive battery cable from the PDC.ĥ. Remove the two nuts used to secure the positive battery cable to the PDC. Locate the ASD (Auto Shut Down) and the Fuel Pump relays in the PDC.Ĥ. Remove the Power Distribution Center (PDC) cover from the PDC.ģ. Remove and isolate the positive and negative battery cables from the battery.Ģ. If the MIL flashes for 10 seconds approximately 15 seconds after turning the key to the ON position (without cranking the engine) and then returns to solid illumination, the vehicle is not ready for I/M testing.ĪR NPN Solder, Rosin Core, 2 05018395AA Kit, Spliceġ.

(See 'Emissions Inspection and Maintenance Programs' in section 7 of the Wrangler owner's manual to determine if vehicle is ready for I/M testing.)Īfter turning ignition key to the ON position without cranking the engine, the Malfunction Indicator Lamp (MIL) should remain illuminated solid. Vehicle On Board Diagnostics (OBD) system will not indicate readiness for I/M emissions NOTE: This bulletin applies to vehicles equipped with a 2.4L or 4.0L engine (sales This bulletin involves modifying wiring in the Power Distribution Center (PDC). I/M Readiness Check Continues To Indicate OBD System Is Not Ready For I/M Testing TSB #25-001-07 deals with I/M readiness, it involves modifying the wiring in the PDC. OBDII makes a final check of EGR and canister purge. Decelerate (coast down) to a stop without braking. (OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.)ħ. Hold at a steady speed of 55 to 60 mph for five minutes. OBDII checks misfire, fuel trim and purge again.Ħ. Accelerate back to 55 to 60 mph at _ throttle. Decelerate (coast down) to 20 mph without braking or depressing the clutch. (OBDII monitors EGR, air pump, O2 sensors and canister purge.)Ĥ. Hold at a steady state speed of 55 mph for three minutes. OBDII checks for ignition misfire, fuel trim and canister purge.ģ.
Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.Ģ. As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. NOTE: The ignition key must not be on prior to the cold start otherwise the heated oxygen sensor diagnostic may not run.ġ. The OBDII drive cycle begins with a cold start (coolant temperature below 122 degrees F and the coolant and air temperature sensors within 11 degrees of one another). Running through the drive cycle sets all the system status "flags" so that subsequent faults can be detected. The drive cycle should be performed after you've erased any trouble codes from the PCM's memory, or after the battery has been disconnected. The purpose of the OBDII drive cycle is to run all of the on-board diagnostics. How can you check your work? By performing what's called an "OBDII drive cycle." This drive cycle may not work for every vehicle. Suppose you've "fixed" an emissions problem on an OBDII-equipped vehicle.

Plus local running around.Īny ideas on what to try next? I have looked at and pushed together as many connections in the wiring as I can find. I did find that my winch solenoid box had an inch of water in it and was hoping that the water sloshing around was causing a brief short and resetting the ECM, but I have fixed that problem and monitors are still incomplete after two wheeling trips each consisting of an 80 mile round trip to the park and wheeling all day. It seems that somehow the ECM keeps getting reset. Next time I check there are 4 incomplete, Catalyst Mon ,Evap System Mon, Oxygen Sens Mon, and Oxygen Sens Htr. I have had as few as 2 monitors incomplete, Evap System Mon and Oxygen Sens Htr. It has not come back since a new gas cap was installed.

No codes were reset since a year ago when I had a slight evap leak code reset. I have put over 4000 miles on since then. The last time the battery was disconnected was in July when I relocated the rear spring mounts. In my particular case there was no battery disconnect or code clearing for at least 6 months, 4 of them as a daily driver. I have searched the problem and all the results returned deal with the drive cycles needed to get the monitors to complete after a reset caused by the clearing of a code or disconnecting the battery.
My Jeep can not pass emission testing due to having two to four monitors incomplete.
