How d I reset not ready monitors

No such thing as resetting an Emission Monitor

What your asking-- is how to clear the dash light--
& ALL Data, you need to diagnose the problems
with monitors that don't run clear, with no problems

First you need to look at the OBD Codes you have
Diagnose those codes & component test & find a problem
& correct it & continue on

Without a Professional Scan Tool your at a disadvantage

If you have cylinder misfires that ruined the converter,then
you have to clean that up & test the oxygen sensors or at
least look at the data

I start with Battery Voltage,Module Voltage,Fuel Trim,MAF Data
& then Mode $06 Misfire Data & Cat Temp & on & on

All but the Evap Monitor should run in about 10 to 20 miles
of driving,not 345

You also have Freeze Frame Data at the time the Monitors
Ran & failed

So NEVER Clear the check light/MIL Lamp, etc
unless ALL issues are fixed & then only if you have to

Fault Codes you need only appear after a monitor runs,
pass or fail,so forget the battery disconnect or code clearing,
you need that data

96 accord v6 2.7 exhaust monitors wont reset

louie ramirez if the monitors are not resetting right away its because something was repaired recently to do with the emissions and a trouble code was erased or cleared to remove the check engine light .now there should be no more check engine light on but you have monitors blinking on your scanner right ,now to turn those monitors off all you have to do is drive the vehicle and monitor with a scanner some cars clear right away and some can take up to 500 miles before the monitors clear ,don't panic its this a typical normal procedure just drive it should clear soon and good luck.

How to reset computer when engine light is on so I can pass emissions on 2004 avalanche

Have you fixed whatever caused the code to come on? If not you will not be able to clear the code and pass emissions. Two reasons - 1. If the problem has not been repaired the check engine light will come back on. 2. Clearing the codes usual means that the OBDII monitors will also be cleared. There will be a code stored for this until the monitors are complete. If they see this co they know what you are up do and you do not pass.

How do you reset the monitors on a hyundai

You may have to drive 300 to 500 miles or more,on multiple days and at different speeds and make sure to include long deaccelerations with your foot off the gas to set the EVAP. Most areas allow 1 monitor "not reset" and still give a full pass.Check your area for allowed number of monitors. If the check engine light stays out,the monitors will eventually reset,but on a older Hyundai it takes time.

Dsc warning light on , bmw e46

Dynamic Stability Control....a derivitave of ABS / Traction control. The control unit that monitors the dynamics will most likely be sensing a difference in the measured wheel speeds. Possibly defective ABS sensor, wiring, ABS exciter ring, ABS module or steering angle sensor. Can also be triggered by wheel spin.
Have a diagnostic scan done ( cost £30 - £50 approx at good local garage) to read the fault codes first. If you get a fault code relating to "ABS module pressure sensor" the module requires replacement (common issue). Used to be a £1400 job, but repair kit now available from dealer for £180 ish and 2 hours to fit.

Abs light on in my 2005 town and country

The ABS light comes on when the ABS module detects a fault in the ABS system. There are dozens of component failures and open/shorts in wiring that will set the ABS light, ranging from a faulty wheel speed sensor, open/short in wheel speed sensor wiring harness, faulty hydraulic unit, fault electronic brake control module(EBCM), faulty tone ring,etc. There isnt a relay or reset procedure to turn the light off- it can only be turned off by repairing the fault responsible for turning it on, and then using the factory scan tool to erase the fault code and reset the light.

While it is possible the majority of the faults to be repaired at home, the fault codes can only br retreived with a diagnostic scanner with ABS capability. This has to be done first in order to know where the problem is to either repair or do further diagnostics to determine if it is a faulty part or a wiring harness issue. If the problem is in the hyrdaulic unit, this would need to be replaced by a shop as it will require bleeding afterwards with a diagnostic scanner.

I would advise spending the $50-70 to have the on-board computer read for stored ABS fault codes. Considering that most sensors cost that much themselves, you can quickly sink much more than a diagnostic fee into replacing parts based on "what usually goes out" guesses

Hope this helped (remember comment and rated this).

I have a 2000 porsche carrera 2, which has PSM & ABS warning lights constantly on. I am unable to use the PSM switch, as it does not respond. My mechanic just replaced a speed sensor on the front...

If you have voltage from all of the speed sensors on the wheels, only then think about getting the ABS pump control repaired or replaced. It could be the reluctor.
I repair Volvo and Mercedes without issue so I think you could get the module repaired at a competent repair shop.
Took me 20 minutes to remove, repair and replace the module on the V70. Mercedes took a bit longer as the module was awkward to get to.
