Removing Instrument Cluster with Key IN is strictly prohibited otherwise it will corrupt the odometer value. 1. Remove cluster hood gently from its position by using screw driver. 2. Tilt down the lower level steering wheel. 3. Carefully pull the steering column upper cover. 4. Lower steering column from top mounting to access lower mounting of Instrument cluster. 5. Loosen the lower mounting screw of the instrument cluster. NOTE: Only loose screws and keep in their position, Do not take out. 6. Now remove the upper mounting screws of the instrument cluster. 7. Remove Instrument cluster electrical connections. 8. Remove Instrument cluster REFITMENT Follow above procedure in reverse for fitment. WARNING Swapping to analyze cluster defect: It is strictly prohibited to swap clusters for defect analysis from vehicles or from available stock. Due to BCM / PEPS Odometer learning strategy, cluster odometer value will change permanently to a higher value. For defect analysis, use Diagnostics Tool or ETC (Engineering Test MOD
ELECTRICAL 27 2. FUSE AND RELAY BOX DETAILS CHECKING FUSES: If any electrical unit in the vehicle has stopped functioning, fuses should be checked first. A blade type fuse has test taps provided to allow checking of the fuse itself without removing it from the fuse block. The fuse is okay if the test light comes on when its one lead is connected to the test taps (one at a time) and the other lead of the test light is grounded. Remember to turn the ignition switch to ON to ensure all circuits are live. CAUTIONS IN EVENT OF BLOWN FUSE When a fuse is blown, there are two probable causes. One is that it is blown due to flow of current exceeding its rating. The other is that it is blown due to repeated on/off current flowing through it. Which of these two causes were responsible for the fuse to be blown can be determined by visual check as described below. 1. Fuse blown due to current exceeding rating The illustration shows the state of a fuse blown due to this cause. In this case, do not replace the fuse with a new one quickly since a current heavy enough to blow the fuse has flowed through it. First, check the circuit for shorts and check for abnormal electric parts. After correcting shorts or replacing parts, use only a fuse of the same capacity as a replacement. Never use a fuse of larger capacity than the original fuse. If a larger capacity fuse is used, electric parts or wiring could be damaged, or could start a fire. 2. Fuse blown due to repeated turning current on and off: The illustration shows the state of a fuse blown due to repeated current on/off. Normally, this type of problem occurs after a fairly long period of use and is less frequent than above. In this case, simply replace with a new fuse of the same capacity. CHECKING RELAYS: 1. By using a relay, a heavy current can be turned on and off by a switch using much less current. For example, in the circuit shown here, when the switch is turned on (closed), current flows to the coil of the relay. Then, its contact is turned on (closed) and the light comes on. The current flowing through the switch is much less than that for the light. 2. Relays may be classified as the normally open-type or the normally closed-type, depending on their contact construction. NOTE: The De-energized state means that no current is flowing through the coil. The energized state means that current is flowing through the coil. (a) The normally open-type When a normally open relay as illustrated here is checked, there should be no continuity between terminals 30 and 87 when the relay is de-energized. There should be continuity between terminals 30 and 87 when battery voltage and ground are applied to terminals 85 and 86. The relay condition is determined by this check. NOTE: Check the relay in both condition, i.e. energized and not energized
ELECTRICAL 28 (b) The normally closed-type When a normally closed relay as illustrated here is checked, there should be continuity between terminals 30 and 87 when the relay is de-energized. There should be no continuity between terminals 30 and 87 when battery voltage and ground are applied to terminals 85 and 86. The relay condition is determined by this check. NOTE: Check the relay in both conditions, i.e. Energized and not energized. (c) The NO NC (Changeover) type It has 2 relay out pins. One will be in contact in the changeover state as in NC relay. When it is energized it brakes the NC contact and connect the other output pins.

Tire Pressure Monitoring System (TPMS) 40 3. TYRE PRESSURE MONITORING SYSTEM (TPMS) A. GENERAL INFORMATION I. INTRODUCTION TPMS (Tire Pressure Monitoring System) provides feature of Tire pressure monitoring. According to the frequent accident due to the insufficient tire pressure, it has been necessary to develop more reliable system to monitor the actual pressure and give a proper telltale to the driver while driving. TPMS is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. TPMS system provides tire condition over CAN i.e. low tire pressure, High tire pressure, High temperature, Air leakage, real time pressure value, TPMS Errors. TPMS system also has tire sensors which are mounted on the inside of the rims.
Tire Pressure Monitoring System (TPMS) 41 II. SYSTEM WORKING III. SYSTEM LAYOUT
Tire Pressure Monitoring System (TPMS) 42 IV. COMPONENTS 1. TPMS ECU The TPMS ECU is control unit that receives RF signal coming from tire sensors and transmit tire condition over CAN bus. TPMS ECU have the following main tasks: 1. If vehicle power mode is IGN ON, TPMS ECU sends tire status information (i.e. Low/ High Pressure/ Air leakage / High Temperature warning indications / Tire pressure and Tire temperature data.) to IPC. 2. IPC displays TPMS screen with 4 tire based on available tire configurations value received from TPMS ECU. PINOUT DETAILS PIN DESCRIPTION 1 +B 3 IG SW 5 CAN L 6 CAN H 7 GND 2, 4, 8, 9, 10, 11 & 12 DUMMY 2. TIRE PRESSURE SENSOR Tire sensor measures pressure and temperature value of the tire and transmit RF signal to TPMS ECU. Each sensor has a unique identifier into the internal memory and the power source is 3V lithium battery cell built in the sensor (cannot be replaced). The aluminum valve body has a function for the antenna.

Tire Pressure Monitoring System (TPMS) 45 C. TPMS ECU LEARNING PROCEDURE Prerequisite: A) All TPMS Sensors and TPMS ECU to be learnt shall be available. B) Check and verify part number of the TPMS ECU. It shall be 550254800102. Why ECU Learning is needed? 1) ECU is not having the respective Tire sensor ID with in its memory as it is recently flashed with updated software. This can be confirmed by reading DID for respective tire by using Diagnostic Tool. The respective DID are as follows: 6408: TPMS Front Left Tire ID 6609: TPMS Front Right Tire ID 640A: TPMS Rear Right Tire ID 640B: TPMS Rear Left Tire ID NOTE Total numbers of TPMS Sensors to be learnt are considered as 4. TPMS learning can be done through two ways: a) By using Triggering tools (LF tool). Triggering tool should be kept near to Tire valve to detect Sensor ID. This is done for all tires including spare. Once all tire IDs are known using LF tool, they are written in ECU using Diagnostic tools. The respective DIDs are as given above. (DID 64XX) b) TPMS Learning can also be done manually by service engineer as given below: For learning process please follow below steps. Execute the TPMS routine 4A01 in order to enter in manual learning mode. Before starting the TPMS learning, drop down the spare tire so you will be able to take out air from it. Respective Tire Sensor ID should be written in ECU using diagnostic tool. Do the following operation in the same sequence. Respective tire is triggered by reducing or increasing tire pressure by 1.2 psi/sec.
Tire Pressure Monitoring System (TPMS) 46 If you observe “flash hazard and two short horn beeps”, the system has successfully entered into learning mode and you can proceed for next steps. Go to front left (FL) tire and start removing / increasing air from that tire by 1.2 psi/sec until hazard flashes and horn beeps once for short time. Stop removing the air and FL tire is learnt successfully. Go to front right (FR) tire and start / increasing air from that tire by 1.2 psi/sec until hazard flashes and horn beeps once for short time. Stop removing the air and FR tire is learnt successfully. Go to rear right (RR) tire and start removing / increasing air from that tire by 1.2 psi/sec until hazard flashes and horn beeps once for short time. Stop removing the air and RR tire is learnt successfully. Go to rear left (RL) tire and start removing / increasing air from that tire by 1.2 psi/sec until hazard flashes and horn beeps once for short time. Stop removing the air and RL tire is learnt successfully. Go to spare tire (SP) and start removing / increasing air from that tire by 1.2 psi/sec until hazard flashes and horn beeps twice. Stop removing air and Spare tire is learnt successfully. TPMS learning is completed successfully. To exit from learning mode, turn the ignition OFF. Fill all the tires to the OEM recommended pressure values. WARNING It is always necessary to follow the above sequence only for air removal from tires while learning. Failing to do so can wrongly learn the TPMS and the indications will be misleading. During learning, TPMS tell -tale and TPMS HMI display on your vehicle Instrument cluster will also show the learning status apart from hazard flashing and horn beeps. If TPMS has successfully entered into learning mode, TPMS tell -tale and tire alert symbol will glow continuously. The tire for which learning is being done will blink continuously and the tire for which learning is successfully completed will glow continuously.
