All u need to do is disconnect the negative battery cable, but what are u doing here, all the component's are protected from static by shielding so in 35 years i never seen any damage except from an arch welder

I have a 2006 chysler sebring 2.4l and ive replaced the head gasket and everything in between water pump thermostat thermostat houseing radator and it still gets hot and also now it starts just fine but it...


Hello Sean Hector,

Typically a half dozen issues COULD be
stopping your START... Get your code read...
and ignore THE COUNTER CLERK's OXYGEN
SENSOR
sales pitch (they seldom solve the issue)

None of this "STUFF" is magic... and everybody
typically starts at the beginning ... but wouldn't it be
nice to know some important TIPS in advance.

Your ECM
(for example) is AMAZINGLY cheap
(eBay: see here)
2004 Chrysler Sebring 2 4L Engine Computer Control Module ECM ECU PCM PCU...

But RE-PROGRAMMING is required (not cheap)...
On my eBay example it is PRE-PROGRAMMED
(see bottom links: 2004 Sebring)

An important NOTE about AUTOMOTIVE electronics...
.(actually ANY semiconductor circuits you care about):

The tiniest static SPARK (you might not even feel)
is enough to UTTERLY DESTROY any semiconductor
on the planet...

Electro-static DISHARGE:
ESD
precautions should always be employed...
(A very simple and cheap [high resistance] wrist band)
Amazon com Rosewill ESD Anti Static Wrist Strap Components RTK 002 Black...

Typically automotive mechanics GET AWAY
with their GROSS NEGLIGENT behavior because
they are usually contacting (grounding themselves)
METALIC body parts, nuts bolts... (etc.) an THEN
touching the various CONTROL MODULES. ECM,
PCM, BCM...TCM (etc.).

ALSO ...
High IMPEDANCE (resistance) test equipment...
or EVEN better... Non CONTACT test equipment
can get your testing done (professional results...
Without EXPLODING those pesky AIR BAGS.
(also quite expensive... never-mind dangerous).
((look on AMAZON for NCVT DC testers))

So as more & more cars are carbon fiber, plastic
(non-metallic et al)... Fewer SEMICONDUCTORS
are going to survive mishandling... I am only
concerned with YOUR CONTROL MODULES.

Hope this gets you SAFELY started

Airbag precautions


I worked at a salvage yard for a while. During that time I pulled hundreds of airbags. I thought I'd share a few things.

I've provided this as a supplemental reference. The precautions are applicable to handling all airbags. It provides important additional information you need to be aware of when working on or around SIR (Supplemental Individual Restraint) airbag systems. It lists the potential dangers of doing so and the appropriate precautions against accidental premature deployment.

Precautions for working with and handling airbags: Take these Seriously!!!
  • Alway wear safety glasses.
  • Control the environment - no kids, pets, people horsing around.
  • Disconnect the negative battery terminal. After you are done, make sure no one is inside the vehicle when you reconnect the battery. If your vehicle has an anti-theft system, you'll need to get your activation codes to reset your sound system.
  • Do not use solvents to clean your airbags. They may ignite if accidentally deployed. Use only a damp cloth.
  • Airbags are sensitive to heat in excess of 190 degrees F. Store them accordingly.
  • Airbags are sensitive to impact - handle them carefully
  • Airbags are sensitive to static electricity - ground yourself, Spray the seat and rug with fabric softener (anti-static - ever heard the term 'static cling')
  • Wires for the SIR are bright yellow, the connectors are labeled.
  • In addition to forward mounted sensors, there can be sensors in the dash.
  • Disconnecting the battery alone is not enough, the diagnostic module can retain a firing charge.
  • Do not use voltage testers or VOM's on SIR wiring.
  • Do not haphazardly disconnect airbag components
  • Be safe
  • Be aware

Disable the system:
  • Turn the wheel to the straight ahead position
  • Lock the ignition and remove the key
  • Disconnect the negative battery cable. Be advised, this alone will not render the system safe. The diagnostic module (DERM) can retain a charge
  • Remove the airbag fuse (refer to fuse block cover for location)
  • At the bottom of the steering column locate the Airbag connector. (Yellow wire, yellow conduit)
  • You may need to remove the sound insulator panel beneath the instruments to access it
  • Disconnect the plug
The system is now disabled. That does not mean you can let your guard down. It means that you can now continue working around the system with a higher degree of safety. Continue to observe all safety precautions. Airbags should be handled with caution at all times.

Be safe

Do I have to remove the Airbag Control Module in order to remove the front seat belts.


The SRS (supplementary restraint system) control module or airbag brain is generally mounted on the inside of the front firewall - buried behind the dashboard and removing it would represent a great deal of unnecessary work.
You should however, observe the safety precautions that apply to working on the SRS of your car as detailed in the repair manual.

Briefly that means disconnecting the battery and waiting for the capacitors to discharge - at least 30 minutes, not checking any wiring with an ohmmeter and taking precautions against static electricity discharges.

Po452 and po446 on 04 chevy silverado have replaced fuel pressure sensor and reset but code po452 keep poping up


P0452 evap control pressure low, P0 446 evap vent contol circuit. Becuase you have P0452 you are dealing with a eletrical issue whether you have positive tank pressure or negative pressure, The tool for this is a volt meter.452 happens when you positive pressure and the FTP reads less than 0.1 volts.You need to jump the signal and the reference and monitor the take parameter on a scan data you should read reference voltage.Now if you dont have a scan data tool. inspect the wire for any breaks or shorting 2 thing of concern broken wire to the FTP or a ECM is needed.

Have 2005 lincoln aviator - has miss at 30-55 MPH - no codes replaced all coils ( ford) & spark plugs (twice) - repair vacuum leak at PCV Still misses -- no codes -- help


The COPS (coils) may have shorted the drivers in the PCM (computer). You should get a misfire code for each cylinder misfiring though.

Slim possibility, but very expensive unless you have a service contract.

ISSUE: Some 1999-2004 Navigator, 2002-2003 Blackwood, 2003-2005 Aviator, 2003-2004 Marauder and 2003-2004 Mustang vehicles built before 12/19/2004 equipped with 4.6L 4V/5.4 4V engine may exhibit a runs rough, lacks power, and engine misfire, prompted by a MIL light and DTC codes P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, and P0316.
ACTION: Diagnose engine for engine misfire concern. If diagnostics determine an engine misfire which is characterized by leakage through exhaust valve(s), only replace the affected cylinder head(s).
SERVICE PROCEDURE FOR VEHICLES WITH RUNS ROUGH/MISFIRE CONDITION:
  1. Perform relative compression check on all cylinders. If abnormal, check cylinder leakage and actual compression for "low" cylinders refer to Workshop Manual (WSM), Section 303-00.
  2. If leakage/compression check indicates a valve train concern, per valve train diagnostics in WSM, Section 303-00, replace cylinder head and cam assembly, pipe plugs and timing chain tensioner, per procedure outlined in WSM, Section 303-01.
  3. If cylinder leakage and compression tests are inconclusive, perform misfire diagnostic, per TSB 05-22-8. NOTE: DO NOT TRANSFER SPARK PLUGS. INSTALL NEW SPARK PLUGS IN REPLACEMENT CYLINDER HEAD AND CAM ASSEMBLY. NOTE: THE ENGINE MISFIRE CONCERN IS TYPICALLY EXHIBITED ON THE LEFT HAND CYLINDER HEAD AND RARELY ON THE RIGHT HAND CYLINDER HEAD. UNLESS CONFIRMED, THE RIGHT HAND CYLINDER HEAD SHOULD NOT BE REPLACED AS AN "EXTRA MEASURE" SERVICE PRECAUTION. NOTE: THE REPLACEMENT CYLINDER HEAD WILL NOT IMPROVE OR REDUCE ENGINE HORSEPOWER OR TORQUE ABOVE ADVERTISED LEVELS.

Dodge nitro wont start or turn over. The battery checks out ok. what could be causing problem??


Is this an intermitting problem only occure during dry and cold weather?
Behind the ignition key lock there is a module call Wireless Control Module (WCM). When this module is zap by static eletricity build up during cold weather (via the key). It will hang just like you computer.
As a test please please touch the key to a metal object to discharge the static on the key before insert it into the ignition.
If the problem stop complete then you can take it to the Dodge dealer the arrange service on the Wireless Control Module (WCM) or wire for better grounding.
