the date noted on the materials and may be revised or updated without notice Always check for revised or updated information To help avoid personal injury to you or others and to avoid damage to the vehicle on which you are working you must always refer to the latest Mercedes-Benz Technical Publication and follow all pertinent instructions when testing diagnosing or making repair Illustrations

authorization from Mercedes-Benz USA LLC or its successors Published by Mercedes-Benz USA LLC Printed in U SA 2 General Information TPC constantly monitors tire pressure Pressure and temperature values are sent from the wheels to antennas using radio frequency Antennas are connected directly to TPC module Ambient temperature and fuel level are supplied via CAN-B TPC module evaluates data and passes it on to the instrument cluster module ICM via CAN-B ICM display informs warns driver of – Sudden pressure loss – Pressure too low – TPC system failure – External interference – Low battery in sensor 3 Advantages Early warning when sudden pressure loss occurs Avoid blowouts due to high speed low pressure conditions Driver is alerted to the need to check tire pressure Pressure can be checked electronically Tire wear reduced -03 bar 25 reduction in service life Increased fuel mileage 4 Survey of Pressure Checking Habits Of passenger car drivers who check tire pressure Weekly 876 When tires seem low 2563 When serviced 3018 Before long trip 099 Other 646 Do not check 656 In a random check of 6442 cars stopping at gas stations 36 had one or more tires that were at least 20 under-inflated 26 had one or more tires that were at least 25 under-inflated Source NHTSA study 5 Important Points How to read out tire pressures electronically How TPC is networked and how it gathers data Part locations What to look for during a tire change How to read information on a wheel sensor How to install a wheel sensor When and how to activate What typical faults might be displayed Service tips for working on TPC 6 TPC Function-typical W220 video 7 Electronic Tire Pressure Check Electronic check 1 Call up the odometer display by pressing steering wheel buttons 2 2 Display tire pressure by pressing steering wheel arrow buttons v Four values are displayed – In either bar or psi – Blanks indicate that no values are stored This is also the display youll see after performing an activation to store new pressure values 8 Basic TPC Components CAN-B Instrument Cluster 4 wheel sensors 4 Antennas in TPC module Module - Pressure wheel housings - Readout values - Temperature - Display warnings - Vehicle speed input 9 Wheel Sensors and Antennas Transmission intervals New sensor inoperative until 15 bar applied for 3 minutes Normal conditions Measure once every 3 seconds transmit once every 55 seconds When pressure drops 02 bar minute Measure and transmit once every 08 second 10 Wheel Sensor and Valve Components Plastic cap 11mm Within the sensor Lock nut - Lithium Battery Spacer ring - Pressure sensor T20 Valve - Temperature sensor Aluminum - 315MHz Transmitter Hollow screw Plastic cap prevents corrosion 11 Wheel Sensor Battery Battery not replaceable Battery life approximately 7 years With each data transmission the sensor reports on remaining battery life DAS can be used to check remaining battery life in months Production date july 151999 stamped on sensor 12 W211 TPC Module N88 At left side of trunk behind rear SAM Task Receive tire pressure and temperature info from wheel sensors Process info received via CAN-B and determine if tire pressures are OK T30 Power and ground supplied by N102 13 Additional Inputs to TPC CAN-B Front left SAM Rear SAM Central gateway EIS - Ambient temp - Fuel level - Country - Ignition on - Charging volts - Trunk lid status - Vehicle specific info 14 Tire Service Stay clear of wheel sensor to prevent damage With tire removed check condition of wheel sensor - no need to remove sensor from wheel to do this Before mounting tire check date stamp on sensor Replace sensor if over 5 years old 43a Wheel weight 43g Wheel sensor 32 grams 15 Wheel Sensor Inspection White filter on underside of sensor – Dont remove it – No compressed air or detergents – Use a clean lint-free cloth Replace entire sensor if – Damaged – Too dirty to clean – Tire sealant was used – Over 5 years old Replace valve if – It has been removed – Screw or nut is loose 16 Installing Wheel Sensor Always use new valve 315mhz must show on US Sensor Electronic ID number Record electronic ID number of sensor 20mm hole in valve must face upward Spacer has 45? bevel on both sides When installing new sensor use 20mm pin 6 to counter hold valve 2 while tightening lock nut 4 Hollow screw and nut both torqued to 4nm 2 4 17 Electronic Identification Number Each sensor has a unique wheel electronic identification number that it sends to the TPC module with each data transmission The TPC module must learn this number and identify it with a specific wheel position on the vehicle The wheel electronic identification number is stamped on the sensor 433MHz indicates European standard US version 315MHz 18 Activation Notes Activation means – Clearing old tire pressure specifications from TPC memory – Storing new tire pressure specification values for each wheel Activation is performed when – Setting a different inflation pressure base-line value – Cluster says to re-activate TPC – Tires are rotated – Winter tires are mounted – A wheel sensor has been replaced – The TPC control module has been replaced – A TPC fault code has been erased Activation is initiated using steering wheel ICM buttons and completed by driving the vehicle 19 Learning Wheel Sensor Location Before new tire pressure specification values can be stored the TPC module must have learned the wheel sensor identification numbers and matched those numbers with their specific location on the vehicle The fastest way for the TPC module to learn this information is by entering it into TPC memory using the DAS program Control unit adaptations settings – Activation will occur faster if sensor locations are already known The slower method of learning is to simply perform an activation While driving first the wheel sensor locations will be learned and then the new pressure specifications will be stored – TPC will have to determine sensor location by measuring field strength at the antennas – TPC must receive a greater number of clear signals from each sensor 20 TPC Activation Procedure 1 Vehicle stationary 2 Tire pressures set correctly 3 Engine OFF Ignition ON 4 Use steering wheel buttons 2 to scroll to 0 mph display S110s1 21 TPC Activation Procedure 5 Use steering wheel buttons to displa
