Flashing check engine light
 

after having numerous electrical problems with my car i just noticed my check engine light flashes 5 times after key is turn to ON position (before run position). what can this be?

How long after you turn on the ignition does this happen? When turning on the ignition, after about 15-20 secs, CEL will flash and go off. This is an indication of the readiness codes being set, and it's normal. If this doesn't happen, its due to either the readiness codes aren't set, or there's something wrong with the car and there's a code stored in the ECM.

You need to better describe the symptoms of CEL

it happens about 10 seconds after i turn the ignition *ON... check out this thread too plz https://acurazine.com/forums/3g-tl-problems-fixes-114/plz-help-turn-signal-remote-wipers-not-working-803054/ let me know if u can help me out or have any ideas...

The only thing i can tell you about the CEL is what i already stated on the first post.
Have all other symptoms disappeared?

no, nothing works...taking it to the dealer tomorrow even tho i didnt want to...

i just dropped off the car at the dealer.... ill let u guys know what they said...

any updates???

this is a reply i found from a dude on a forum. i have the same problem, i noticed it today

Take a look in the 'Owner's Manual' for the section titled 'Malfunction Indicator Lamp'. It is on pg. 310 in my manual for the CLS-6. It states:
'This indicator comes on when you turn the ignition switch ON (II) and goes off after the engine starts. If it comes on at any other time, it indicates one of the engine's emissions control systems may have a problem.'

Furthermore, if you look on pg. 311 under the section 'Rediness Codes' it states the following:
'Your car has certian "readiness codes" that are part of the on-board diagnostics for the emissions systems. In some states, part of the emissions testing is to make sure these codes are set. If they are not set, the test cannot be completed. If your car's battery has been disconnected or gone dead, these codes are erased. It takes several days of driving under various conditions to set the codes again. If possible, do not take your car for a state emissions test until the readiness codes are set. To check if they are set, turn the ignition ON (II), but do not start the engine. The Malfunction Indicator Lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks 5 times, the readiness codes are not set.'

This is the only instance I can find in the Owners Manual that mentions anything in regards to a (5) blinking CEL at start up.

I have a S/C'd CLS-6 and the CEL always goes 'OFF' after 20 seconds or so, when the car is initially started. The CEL has never blinked 5 times at first start.

Therefore, per the book, it leads me to believe that this 'blinking (5) CEL at start-up' is related to the setting of the 'Readiness Codes' in regards to the emission system.

If it does not go away after awhile, then it may be advisable to visit the local 'stealership'.

Sorry for the long post, but that's all I could find.
Peace.
