DTC P0016: Crankshaft Position (CKP) - Intake Camshaft Position (CMP) Correlation Bank 1
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1
A camshaft actuator stuck in the full actuation position may cause the engine to crank but not start.
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the park position, and the locking pin retains the CMP actuator sprocket to the camshaft. The park position for the CMP actuator and camshaft is 8.5 degrees before top dead center (BTDC), which is equal to 17 crankshaft degrees BTDC. The engine control module (ECM) can only command the CMP actuator to retard the valve timing from the park position, or advance the valve timing back to the park position. The total range of valve timing authority is approximately 20 degrees of camshaft rotation, which is equal to 40 degrees of crankshaft rotation.
Problems with this will cause the PCM to disable traction control and Stabilitrac .How many miles on your vehicle ?
Chevy Colorado P0017 Case Study Part 1 GM is a GM , Chevy , GMC , Buick , Cadillac etc.....
Hello Brooke Smith,
There are several technical service bulletins on General Motors
REMOTE KEYLESS ENTRY systems...
Most likely was the remotes have functioned as designed... if a FOB's button has been depressed for more than 30 seconds that button is de-activated until another button is depressed...
See the URL below...
Interesting approach: states that ALL buttons should be operated until functionality returns...
Failing that reprogram the FOB to the vehicle...
Sadly I know NOTHING of this procedure.
(on my LINCOLN that procedure is in the owners manual)
(()My Jaguar cautions ALL FOBs must be present.. & re-entered).
Before I would resort to any of that you have a radio receiver fused on your "INTERIOR" fuse panel... called X1 number 21...
It is a 10 amp fuse... Check that out first...!!
Good luck.
There is also a technical bulletin on a possible connector issue.. but I'm hard pressed to relate that o a brake-check/tire-change (?).
As shown on the body , security accessory schematic also available on the URL below
Happy hunting.. hope this helps!

You probably won't like this answer, but unless you are a glutton for punishment, as well as highly mechanically inclined, just take the truck to a mechanic. The headlamp bulb is inside a plastic headlight assembly like a pickle in a hamburger. To get to the pickle, you first have to open the bag, unwrap the burger, then separate the burger to get to the pickle. NO JOKE.
There are a ton of plastic parts you must remove to gain access to the headlamps. These tupperware components tend to self destruct even if you are very careful. Plan on needing at least two or three new plastic GM body rivets. The splash guard and eyebrow as well as the front bumper cover must be taken loose to gain access to the bolts that secure the headlight assembly to the frame. The plastic beauty apron must be removed above the headlight assembly. The grille above and attached to the bumper cover has to be loosened as well.
By the time you are actually birth the headlight assembly out of the front quarter of the fender, you'll be sorry you even tried. Then you get to dismantle the actual headlight assembly to change the lamp inside. Don't lose the dozen or two bolts, rivets, and assorted fasteners while you fight with the headlamp assembly. Test your new light before you secure all the parts back together.
This guy had to do 4 videos to illustrate the repair!!!
For issues like this you need an auto electrician with a pro grade bi-directional scan tool computer to diagnose. The misfire may just be spark plug condition, but it could be a sensor issue. It is better to pay a pro and only change the parts that need it rather than 'let's try replacing this' method of repair.
A 2010 Acadia has GM PasskeyIII security. It requires a transponder key programmed to operate with the vehicle. Your "plain key" must have a transponder encased in the plastic head of the key and was programmed to work with your vehicle.
The random no crank is likely because the immobilizer is sometimes unable to validate your key. Could be the key or a problem with transceiver in the ignition lock assembly.
If you have a second key and it has the same issue then the problem is not likely the keys but with the transceiver.
Door Lock System Components
The power door lock system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of the rear doors.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the rear doors
• Body control module (BCM)
• IP BEC
• Reversible door lock actuators in each door
Driver and Passenger Lock System Operation
The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two-position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitor these inputs and send a LAN message indicating a change in the switch position. Modules, that activate the power door lock motors, receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle doors. The body control module (BCM) upon receipt of a lock or unlock signal will control the rear door lock or unlock relays and also send a LAN message to the DDM and PDM to perform the commanded function.
The modules that activate the power door lock motors are:
• DDM (driver door lock actuator)
• PDM (passenger front door lock actuator)
• BCM (both rear door lock actuators)
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other, causing the doors to lock or unlock.
The rear passenger doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. This energizes the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.
Everything you mention is in the same door. Look for a connector between the body and the actuators in the door. This may be accessible or just inside the door itself, past a rubber grommet. Pull the connector apart and inspect it. Spray with silicon or WD40 and reassemble.
usually the underneath connector is just loose .try to remove the connector and clean .if the same problem occurs check the for the ground and blown up fuse
On most vehicles there are 3 blinker bulbs on each side. One at the front corner, one at the rear corner and a third side repeater usually mounted in the front wing, (fender).
Some more modern car companies have started fitting the side repeater into the door mounted 'wing' mirror body.
The blink rate will usually be around 60 to 120 flashes per minute. If the rate on yours is usually slower, a higher speed flash suggests there is a blown or missing bulb.
DTC P0877: Transmission Fluid Pressure (TFP) Switch 4 Circuit Low Voltage
The transmission fluid pressure (TFP) switch 4 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The TCM supplies 12 volts to the TFP switch 4 on the TFP switch 4 signal circuit; the TFP switch 4 has an internal case ground. TFP switch 4 is normally closed, Low. When oil pressure is present at the TFP switch 4, the switch is open, high. The normally low clutch pressure control (PC) solenoid 4-5 controls the transmission fluid to the 1-2-3-4 clutch. The TCM monitors the normally closed TFP switch 4 signal circuit to determine the 1-2-3-4 clutch status.
P0877
The TCM detects that the TFP switch 4 signal voltage remains low, 0 volts when the 1-2-3-4 clutch is commanded ON for 5.5 seconds or greater.
Action Taken When the DTC Sets
• DTCs P0877 and P0878 are Type C DTCs.
• The TCM freezes transmission adaptive functions.
Circuit/System Testing
Ensure the TFT is near the temperature displayed in the Failure Records.
Start the engine and place the transmission range selector in D6.
Observe the TFP switch 4 parameter while commanding 4th gear and then commanding 5th gear with the scan tool. The TFP Switch 4 should transition from High in 4th gear to Low in 5th gear.
? If the TFP switch 4 parameter state does not change, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection .
? If no concerns are found, replace the control solenoid (w/body and TCM) valve assembly.
Component Testing
Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection .
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
Control solenoid (w/body and TCM) valve assembly replacement - refer to Control Module References for replacement, setup, and programming.
Perform the Service Fast Learn Adapts
My personal suggestion would be to go for these repair catalogs. I know this website www.reliable-store that i used to buy them from, and they sold online it was very good manual. Go ahead, I bet.
There should be a lever at the base which allows the seat to fold forward then a secondary latch unlocks the pivot to allow removal. If you need further help, reach me via phone at https://www.6ya.com/expert/james_8f14c50d9c6cdea8
