# Service bulletin PIP\-5122\-D A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10078889 - Published by NHTSA: 2016\-08\-25 - Manufacturer's number: PIP\-5122\-D - Manufacturer's date: 2016\-05\-18 - NHTSA component: FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY ## NHTSA's summary THIS PRELIMINARY INFORMATION COMMUNICATION PROVIDES INFORMATION TO THE TECHNICIANS FOR DIAGNOSING AND REPAIRING VEHICLES THAT HAVE AN ISSUE WITH A POP NOISE FROM THE FUEL TANK AREA AFTER A COLD START OR EVAPORATIVE EMISSIONS SYSTEM PURGE. TECHNICIAN WILL BE ABLE TO USE GLOBAL DIAGNOSTIC SYSTEM 2 TO DUPLICATE THE CONCERN BY COMMANDING A PURGE AND SEAL ON THE EVAPORATIVE EMISSIONS SYSTEM. REPLACEMENT OF THE AUXILIARY FUEL PUMP MODULE ASSEMBLY WILL CORRECT THIS CONCERN. ## The document No address for NHTSA's copy can be built for this communication. Ask the dealer for it by the manufacturer's number. ## Components Fuel system, Fuel tank ## Vehicles listed - 2010 to 2017 CHEVROLET EQUINOX - 2010 to 2016 GMC TERRAIN ## Other bulletins for the same vehicles and component - [PI0865D](/bulletins/10140407.md), 2018-06-11, Service bulletin: FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES; ENGINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE. This preliminary information bulletin provides a information and a procedure on the 2.4L ecotec engine. - [PIP5122F](/bulletins/10137168.md), 2018-05-21, Service bulletin: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. This Preliminary Information communication provides information to the technicians for diagnosing and repairing vehicles that have an issue with a pop noise from the fuel tank area after a cold start or Evaporative Emissions System purge. Technician will be able to use Global Diagnostic System 2 to duplicate the concern by commanding a purge and seal on the Evaporative Emissions System. Replacement of the auxiliary fuel pump module assembly will correct this concern. - [PIT4943D](/bulletins/10114954.md), 2017-08-15, Service bulletin: FUEL SYSTEM, GASOLINE; FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. This Preliminary Information communication provides information to the technician about vehicles that have a Service 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. - [PIP5122E](/bulletins/10114818.md), 2017-08-15, Service bulletin: FUEL SYSTEM, OTHER:DELIVERY:FUEL PUMP; FUEL SYSTEM, GASOLINE; FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY.

This Preliminary Information communication provides information to the technician about vehicles that may have difficulty filling the fuel tank and / or experience fuel spit\-back when fueling. Technician will follow published Service Information diagnostics to determine a root cause. If Service Information diagnostics does not isolate the cause of this concern, dealer should replace the fuel tank assembly and fuel pump assembly O\-ring seals. - [PIP5122](/bulletins/10063200.md), 2016-04-26, Service bulletin: FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY.
