Recently i changed my dead battery and cleared all codes, today i decided to see what the DTC will bring me
I have :
PCM p0410
PCM p0741
IPM b0249
IPM b0429
RIM c0660

and 1 History PCM P0507

By searching the forums i know now what these means but, my question is how can i pass the emission test ? someone here suggest to clear the codes and drive on 3rd for a while to pass the PCM P0741, what about the PCM P0410 ? how can i "cheat" that ?

the IPM and RIM codes are for the AC system and ride control, I don't think that will effect the emission test right ?

and If i want to fix these PCMs how much it will cost me ? range ?

Thanks in advance

Go back to the code sticky or your online code definition lists, post the meanings of your DTC's and whether each is Current or History.

:cool2: We don't memorize them all, either.............

The P0410 requires system diagnosis and checks of the AIR system - and that code is an emissions failure.

On P0741, slipping torque converter clutch, you cannot pass emissions tests by driving in 3rd in your 2003. That trick does not work for models 2000 and later (I don't know about older models). At least for 2000 & up, the test for P0741 runs in 3rd gear per the FSM and also per my experience. So you'll have to get this one fixed to pass emissions. Costs about $1,500 at a good indie shop - make sure they know this transmission well - and $2,000+ at a dealer. Read further about it at this link:

Sorry mate,
PCM p0410 : Secondary Air Injection (AIR) System
PCM p0741 : TCC System Stuck Off
IPM b0249 : Heater/Defrost/AC Door Range Error
IPM b0429 : Temperature Control #3 Rear Circuit Range/Performance
RIM c0660 : Level Control Exhaust Valve Circuit Malfunction
History PCM P0507 : Idle Speed High

@ 70cougar, thanks for the link, I'll make sure to read it again more thoroughly

........and the P0741 has several "workarounds" for different year and model Cadillacs with the 4T80E setup.

You can pull and clear codes using the car's built-in code scanner/reader/memory. Study the sticky thread "How to pull codes".
