| PIP5427B | 2019-04-08. Service bulletin. This Preliminary Information communication provides information to the technician about vehicle that may have a Service Engine Soon Malfunction Indicator Lamp on. Technician may find Diagnostic Trouble Codes P2635, U0074 and or U18A2. Technician will need to follow published diagnostics for Diagnostic Trouble Codes U0074 would take priority over U18A2 if both set before addressing DTC P2635. |
| PIP5427A | 2018-05-21. Service bulletin. This Preliminary Information communication provides information to the technician about vehicle that may have a Service Engine Soon Malfunction Indicator Lamp on. Technician may find Diagnostic Trouble Codes P2635, U0074 and or U18A2. Technician will need to follow published diagnostics for Diagnostic Trouble Codes U0074 would take priority over U18A2 if both set before addressing DTC P2635. |
| PIT5481C | 2018-02-21. Service bulletin. This Preliminary Information communication provides information to the technician with additional information on the functionality of Lane Keep Assist.Starting with2016 model year Lane Keep Assist Regular Production Option Code (UHX) replaced Lane Departure Warning Regular Production Option Code (UFL). Lane Keep Assist is designed to assist the driver in keeping the vehicle from drifting out of a driving lane that has clearly identified markings. The electric power steering provides a gentle steering correction if a lane marking has been crossed and the driver has not actively responded. |
| PIT4943D | 2017-08-15. Service bulletin. 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. |
| PIP4786A | 2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may have low oil pressure message. Technician may also find a Diagnostic Trouble Code P0521 in the Engine Control Module. Technician should follow all published Service Information diagnosis. When using a scan tool if the oil pressure is low but the oil pressure at the oil filter housing is correct, technician should inspect the Valve Lifter Oil Filter for debris/sludge that could be restricting oil flow to the oil pressure sensor. Technician should remove the Valve Lifter Oil Filter and clean it. If the Valve Lifter Oil Filter cannot be cleaned replace it. |
| PIP5272 | 2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may have low oil pressure after an oil change. Technician will inspect the oil filter part number PF63E. Part number PF48 oil filter will fit but will cause a low oil pressure concern. |
| PIP5411D | 2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may have hesitation or a stalling condition while in ambient temperatures 100 degrees or higher. Technician may find Diagnostic Trouble Codes P2635 and or P018B set. The dealer is advised to replace the in tank fuel pump module assembly to correct the condition. Dealer directed to follow latest version of PIP5507 if the fuel pump does not correct the concern. |
