| PIP5226B | 2018-02-21. Service bulletin. ENGINE. This Preliminary Information communication provides information to the technician about finding needle bearings during an oil change. Technician will gain access to the roller rockers to inspect them. Only replace the roller rocker that is missing needle bearings. Be sure to clean the oil drains to retrieve the needle bearings. Each roller rocker has 66 bearings. |
| PIP5540A | 2018-02-21. Service bulletin. ENGINE. This Preliminary information communicates to the technician the need to inspect the induction system for potential icing issues in very cold ambient temperatures. To allow the ice to melt so that it can be drained from the related components. That any of the listed DTC's may set with or without poor engine performance. |
| PIP5130J | 2018-02-21. Service bulletin. ENGINE. This Preliminary Information communication provides information to the technician how to diagnose and repair a vehicle with an engine that runs with an intermittent crank no start with a Diagnostic Trouble Code P0011 or P00C6 current or history. The Camshaft Position Actuator Solenoid Valve may be sticking or binding causing the valve timing to be retarded. Dealer will need to cycle the Camshaft Position Actuator Solenoid Valve by energizing it using Global Diagnostic System 2. |

This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp on. Technician may find a Diagnostic Trouble Code P0011. If the technician has followed all published Service Information diagnosis and has not come to a conclusion, technician should check the oil pressure at the oil pressure sender. Then the number two cam bearing should be inspected. |
| PIP5069A | 2017-08-15. Service bulletin. ENGINE; ELECTRICAL SYSTEM. This Preliminary Information communication provides information to the technician about vehicles that have a lack of power on initial acceleration from a stop when the ambient temperature is approximately 103 Fahrenheit or greater and may include engine detonation or pre-ignition type events as temperatures approach 120 Fahrenheit. Technician will need to perform published Service Information diagnosis first. If Service Information diagnosis does not isolate the cause of this concern, take a Tech 2 snapshot of the concern happening and note the Spark Parameter in the Ignition Data List. If it drops near/below 0 degrees during the concern, check if there is a cylinder that shows any knock. If there is a knock in any cylinder perform a top engine clean. If the concern is still present, then switching to premium fuel (91 octane or higher) with detergents (Top tier fuel) when ambient temperatures exceed 110 Fahrenheit degrees, this should provide a slight improvement in engine performance when ambient temperatures are high especially as temperatures approach 120 Fahrenheit degrees. |
| PIP5130F | 2017-08-15. Service bulletin. ENGINE; EQUIPMENT ADAPTIVE/MOBILITY. This Preliminary Information communication provides information to the technician how to diagnose and repair a vehicle with an engine that runs with an intermittent crank no start with a Diagnostic Trouble Code P0011 or P00C6 current or history. The Camshaft Position Actuator Solenoid Valve may be sticking or binding causing the valve timing to be retarded. Dealer will need to cycle the Camshaft Position Actuator Solenoid Valve by energizing it using Global Diagnostic System 2. |
| PIT4943D | 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. |
| PIP5179B | 2017-08-15. Service bulletin. ENGINE; EQUIPMENT:MECHANICAL; FUEL SYSTEM, OTHER:FUEL INJECTION SYSTEM. This Preliminary Information communication provides information to the technician about vehicles that have extended or long crank time during cold ambient air temperatures. Direct Injection systems run at higher pressures, and the mechanical pump on the engine must build up the required pressure before the first injection event occurs. Direct Injection engines may have slightly longer cold crank times than that of port fuel engines. |
| PIP5341 | 2017-08-15. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ENGINE. This Preliminary Information communication provides information to the technician about vehicles that engine runs and idles rough. Technician will find P0171 and or P0174. Technician will need to inspect the positive crankcase ventilation tube for a vacuum leak on the left side of the engine. Replace positive crankcase ventilation air tube and cover it with conduit to protect from repeat damage. |
| PIP5199A | 2017-08-15. Service bulletin. ENGINE; EQUIPMENT ADAPTIVE/MOBILITY. This Preliminary Information communication provides information to the technician about vehicles with a crankshaft balancer appears to be out of balance or wobbling while watching it with the engine running. Technician will need to check crankshaft balancer run out. If the balancer run out is greater than 0.25mm the crankshaft balancer will need to be replaced. |
| PIT5202C | 2017-08-15. Service bulletin. ENGINE; POWER TRAIN; SERVICE BRAKES, HYDRAULIC:POWER ASSIST. This Preliminary Information communication provides information to the technician about vehicles that are equipped with 6L80 Regular Production Option Code (MYC), 6L90 Regular Production Option Code (MYD) or 8L90 Regular Production Option Code (M5U) Automatic Transmission.
