# Service bulletin PN\-128 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: 10041585 - Published by NHTSA: 2011\-10\-11 - Manufacturer's number: PN\-128 - Manufacturer's date: 2011\-09\-07 - NHTSA component: SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE; SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM:HOSES, LINES/PIPING, AND FITTINGS ## NHTSA's summary SAAB: USING BY REPLACING CHECK VALVE, VACUUM PIPE CAN BE SERVICED. \*PE ## 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 Brakes ## Vehicles listed - 2006 to 2010 SAAB 9\-3 ## Other bulletins for the same vehicles and component - [15\-00\-89\-004E](/bulletins/10222777.md), 2022-10-11, Service bulletin: POWER TRAIN; SUSPENSION; ENGINE AND ENGINE COOLING; SERVICE BRAKES, HYDRAULIC; STEERING. This service bulletin provides technicians with updated information to help identify the differences between what is considered a fluid leak, and what is considered fluid seepage. - [PIT3271J](/bulletins/10168960.md), 2019-12-09, Service bulletin: WHEELS; SERVICE BRAKES, AIR:ANTILOCK. This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection. - [16\-NA\-223](/bulletins/10126062.md), 2017-12-22, Service bulletin: SERVICE BRAKES. This informational bulletin provides information on installing the correct tires for vehicles with the condition of under hard acceleration at higher speeds, the traction control light will flash. Or, they may come in for ABS or general handling/braking concerns. - [PIT4907A](/bulletins/10112560.md), 2017-08-15, Service bulletin: SERVICE BRAKES. This Preliminary Information communication provides information to the technician about brake rotors on new vehicles and replacement parts from General Motors Service Parts Operations. Technician should be advised the costing should not be removed from the brake rotor it will wear off with normal brake usage. Dealer should communicate to the customer this condition is a normal operating characteristic of their vehicle. - [PIT4943C](/bulletins/10111927.md), 2017-08-15, Service bulletin: EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; FUEL SYSTEM, GASOLINE; SERVICE BRAKES, HYDRAULIC. 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. - [3712649](/bulletins/10021408.md), 2007-04-24, Service bulletin: SERVICE BRAKES, AIR:ANTILOCK:WHEEL SPEED SENSOR.
