Hello, after having replaced my battery, this is the second time, I am going through the nightmare of having the car pass smog in California. The car will pass smog however I can’t seem to figure out how many miles or what speeds etc. etc. I need to put on the car so it RESETS the onboard diagnostics to even begin the smog test. The other day I drove 120 miles on the freeway had the air conditioner on, defrost on etc. etc. and still the computer says it’s not ready to test start the test. Does anyone have any advice? I have looked up some Chrysler Drive cycle requirements however I don’t know if they are specific to the crossfire. This is becoming so annoying thank you

 

To my understanding after a low battery or battery install is done the Crossfire needs to be driven at several different speeds alternating between light acceleration and then decreased speeds
Then some hard pedal to the floor accelerations from a dead stop up to around 60 to 80mph several times with slowing down quickly between these runs
This is what I did and within 50 miles all the emissions tests were on the OBD2 read out on my Crossfire and it passed with no issues at all

 

Valk is correct. It also needs 8 or 10 cold starts. It will only register a cold start every 8 hours.

 

There is a way of maintaining the smog figures in the cars memory by using another battery while swapping the new battery in. But I have forgotten how, I have a rough idea but maybe someone can spell it out for us .
There is a thread on this forum that says how you should do it in detail.

 

Couldn't a battery tender be used to maintain the voltage while swapping the battery? Theoretically the system wouldn't lose it's memory.

A number of years ago I saw a product that plugged into the cigg lighter socket and fed 12 volts (low current) through the car BUT the brain dead engineers at Benz decided the car didn't need a hot cigg lighter socket when the car ignition switch was in the off position. In the interim, get an alarm or battery backup battery (12v 7amp) and clip POS onto the little black fuse pack ahead of the heater solenoids forward of the battery. Hot to the buss there and of course NEG to a ground. Be careful with taking the battery cables off the car battery (I would still use the NEG cable off first, then the POS), if the POS cable touches any ground (remember the 12v 7amp battery is in the circuit) it may damage something. That will maintain system voltage for the short time the car battery is being replaced. After the new battery is installed and connected properly, just unclip the 'HOLD' battery wires (for lack of a better term?).
