vehicles that may have oil mixed in with the engine coolant. Technician will need to inspect the oil cooler if equipped for possible leaking into the cooling system through the radiator. If no issue found replace the engine as well as all rubber coolant hoses.

Engine Soon Malfunction Indicator Lamp. Technician may find Diagnostic Trouble Code P0442. Technician will need to review Techlink article from May 2013 titled "Using the Evaporative Emissions System Tester" Technician will need to follow these steps to help diagnose the issue. First after the P0442 has been verified do not disturb any of the fuel system components. The technician now can use the scan tool to close the Evaporative Emissions System. If possible change the tank pressure sensor units from inch_H2O to milimeter_Hg for better resolution. Now the vehicle can be stared to monitor the tank pressure sensor output value for approximately two minutes. If the tank pressure sensor value does change, pressurize the fuel tank side of the purge solenoid with the GE 41413-A / J 41413-A and the necessary adaptors. Now add smoke and allow pressure to stabilize for 2 minutes. If smoke is allowed to pass through the purge solenoid, replace the purge solenoid. If the tank pressure sensor value does not change, then install CH-48096 adaptor between the purge line from the canister and the purge solenoid. With the Evaporative Emissions System closed, pressurize the system through the CH-48096 adaptor and allow the system to completely stabilize, by observing the Press / Vac Gauge for a minimum of 5 minutes. Now add smoke to the system with GE 41413-A / J 41413-A after system stabilization. Now inspect the purge solenoid, engine side, fuel cap, canister vent solenoid filter and any line quick connects. When the leak is unable to be located, test under a vacuum condition. his type of leak may be detected by using the scan tool Purge/Seal function to create a vacuum in the Evaporative Emissions System and then observe the FTP sensor parameter for vacuum decay.

vehicles with a rattle, tick, or knock type noise. Technician will use chassis ears to listen to the right and left side of the engine and isolate which bank the noise is from. Technician should now remove the piston and rod assemblies from the affected bank to inspect for a loose rod bushing in the rod, or a loose wrist pin in the bushing. There should be no metal through the oil and a piston and rod assembly will repair this noise. If technician finds metal refer to the latest version of PIP5216. If no wrist pins or bushings are found loose and all other diagnostics for this type of noise has been exhausted then engine replacement may be necessary.

If there are any drivability concerns they should be addressed prior to the following diagnostic progression. Technician will take a sound file or video with sound of the noise prior to dis-assembly. Technician may find this noise hard to isolate to one area in the engine. There are four different steps to take to diagnosis the concern. Technician will perform injector diagnosis to ensure there are no leaking injectors causing a noise due to excessive fuel in any one cylinder. Replace any out of specification injectors the reevaluate for the noise. Technician will remove the intake manifold and visually inspect for excessive carbon on the intake valve stems and top of the valve causing noise. If carbon is present then follow the latest version of PIP5029 to clean the valves or replace heads as needed. Technician will remove the cam cover of the affected bank (both if needed) to inspect for soft or spongy stationary hydraulic lash adjusters. Push down on the rocker end at the stationary hydraulic lash adjusters to test for soft or spongy. If soft or spongy stationary hydraulic lash adjusters are found, carefully remove the affected head and inspect the oil passage below the head gasket for debris. If debris is found, inspect the camshaft caps for wear or discoloration due to lack of oil. During inspection if wear or discoloration is found then replace the cylinder head assembly with camshafts. If there is no wear or discoloration, clean the oil passages and replace the head gasket. Technician will use chassis ears or a stethoscope; listen to the right and left side of the engine. Once the noise is isolated or if unable to isolate, remove the piston and rod assemblies from the affected bank(s) to inspect for either; a loose rod bushing in the rod, or a loose wrist pin in the bushing. If this is found, replacing the piston an

Also technician may find a P228C set as current or history, and a prior history of High Pressure Fuel Pump replacement, and the customer has been using E85 fuel. If the Diagnostic Trouble Code is current follow Service Information instruction for the repair. If the code is set in history and there are no current drivability concerns take a large fuel sample and let it sit for a couple of hours looking for contamination. Verify the fuel pressure using a scan tool the actual and desired fuel pressures are very close to the same. If contamination is found in the tank then completely flush the fuel system and add e-10 fuel. Also remove the high pressure fuel pump inlet line from both ends. Using regulated air down to about 60 pounds per square inch or lower, blow through the inlet side of this pipe / hose. Inspect for restriction in the check valve built into this hose. If restricted then replace the pipe run a tank of premium fuel through the vehicle and reevaluate the concern.

This message was to inform dealers that bulletin 15806 was not released as scheduled on Monday, May 16, 2016. This action was necessary due to an anomaly in the calibration testing that resulted in the instrument panel cluster odometer not operating as intended. The affected calibration has been temporarily disabled and will not be available until further testing has been completed. Unfortunately, the decision to hold the bulletin was made after the involved vehicles were updated in IVH. This resulted in 15806 being identified as ?open? in the required field actions section and was quickly reversed to remove the field action.

One type of unwanted call can be made if the key pad is faulty the OnStar system will try to make a blue button call for shorted voltage in the circuits. The OnStar module could have an internal fault and produce a "Phone Unavailable" audio message also it may have a Diagnostic Trouble Code U1500 or B1000. Refer to diagnostics for the Diagnostic Trouble Code making sure to follow any applicable Bulletins or Preliminary Information sheets. A "Ready" or "OnStar ready" audio message heard while driving.

Technician may find Diagnostic Trouble Code B2470-04 set in the Vehicle Communication Interface Module also a red LED on the OnStar keypad will be on. Technician will need to follow published diagnostics for the Diagnostic Trouble Code. If the diagnostics lead to replacement of the Vehicle Communication Interface Module read the OnStar Customer Identifier using Global Diagnostic System 2. If the value falls in range the technician will need to remove power from the module for 5 minutes. After the power cycle was performed, check for the Diagnostic Trouble Code to be set current or history. If the Diagnostic Trouble Code is current replace the module. If the Diagnostic Trouble Code is history no further action is required.
