2006 Cadillac DTS. I need wiring diagram for it please?
Hi Joan Whittaker,what does no crank mean.
the starter motor is dead? some posters call d crank= running engine.
which engine there?
cranks fast but will not start.
underhood fuse box f24 blown?
step 2 after all fuses checked is:
shift to Neutral see if that allows cranking per my red circle below
is PCM control.
is the dash IMMO lamp happy?
as you can see the pcm decides to do the cranking or not
via its starter relay.
if you scanned the PCM it will tell you why it id not start.
immo error OR A/t PRNDL (TRS) ERRORS. OOPS
the IMMO page in your users guide covers IMMO
if key 1 fails try key2, car came with 2 keys new.
READ ALL PAGES ON IMMO FIRST

Where is the air injection relay?
• The AIR pump relay--The AIR pump relay supplies high current and battery voltage to the AIR pump. The ECM commands the relay ON by supplying a ground to the relay control circuit.
• The AIR CNTRL relay--The AIR CNTRL relay supplies high current and battery voltage to the AIR solenoid. The ECM commands the relay ON by supplying a ground to the relay control circuit.
Both of these are in the underhood fuse / relay box. Should be labled
2006 Cadillac dts dies
With all the electronic's on your vehicle this type problem is hard to diagnose. It would be better if it died an didn't start back up , then it could be diagnosed . Your vehicle has a number of electronic control module's , sensor's etc..... Plus the modules all share information on a serial data bus ,communication network . A loose connection ,a module not sending info. ,anything like this could bring down the data bus an cause it to die. I feel for you , the dealer shouldn't have just replaced part's like that if they were not sure . Problems like this can take a long time to pin down . Hooking up testing equipment , using a 8 channel lab scope to check electical signals to an from the PCM , BCM ,data bus. Could take a lot of diagnostic time . Did you buy the vehicle new ? Get the factory Rep. involved , engineers from cadillac etc. When i have a problem vehicle at the dealer that's what i do , call tech help line .
I have a 2006 Cadillac dts with 50,000kms and
Sometimes the front suspension bushes will squeak when you hit bumps, and occasionally it will be a shock absorber. If this does not turn out to be the case, I would just take it to another dealer and ask them to look at it.
