SAFARI BSVI SERVICE MANUAL

ELECTRICAL 169 b) BCM shall update this byte as “Keys Paired (0x01)”, if all requested no. of keys paired and routine executed successfully. When this status is received by the Tool, it shall display ‘Key learning paired successful’ to user. If the first key has learnt successfully this byte update as 0x00, then BCM should ready for next key learning and update this byte as 0x01 until all requested number of keys paired successfully. c) BCM shall update this Byte as “Key pairing failed due to Timed out (0x02)”, If BCM not received key response (Lock & unlock) within the time, then it should update this byte as 0x02 before exit from routine. In this case Tool shall display “Key Pairing execution is unsuccessful due to Timed out for Lock & Unlock press” message and exit from the routine. d) BCM update this Byte as “Keys paring Failed due to same paired key ID (0x03), if user presses the already learnt key, then BCM should compare it’s ID with the learnt & stored key ID and should respond to tool as 0x03 for routine results request. In this case the tool shall display “Key Pairing execution is unsuccessful due to same paired key ID” message and exit from the routine. (BCM should do the comparison from the second key ID onwards with all previous learnt key’s ID). Whenever BCM going to update this byte as 0x02 or 0x03, it shall erase the previous learnt keys ID’s from it’s stored memory and exit from the routine execution. Byte 2 – BCM shall remember the no. of key pairing and update this byte and also in memory after successful paring is done for respective key. Tool shall read the same and display & update to the user. If BCM identifies Timed out or same key ID, update this byte as 0x00 for routine result response, i.e, paired keys shall be erased from memory and exit from the routine. If BCM is in continuation of routine execution process for 1st key then it shall update this byte as 0x00 upon routine result response from tool (i.e., 71 03 34 0E 04(RS) 00 00), during 2nd key execution shall update as 0x01(previous key paired status i.e, 71 03 34 0E 04(RS) 00 01), and Tool shall again request the same after some time. f. Tool shall request the Routine results to BCM every 2secs of time till the routine execution is complete either successful or unsuccessful. g. BCM shall update DID 4429 with key ID after each successful key paring. h. After successful learning of all keys tool should display “ Keys learning routine execution is successful” and shall stop further actions by user. 15.Update BCM ECU VIN with following procedure a. Turn the IGN ON again and Unlock security to BCM ECU with the help of diagnostic tool. b. Read VIN from BCM ECU (22 F1 90) c. Write correct VIN in BCM ECU (2E F1 90 XX XX) d. Read VIN from BCM ECU (22 F1 90) and verify. 16.Configure the BCM ECU (parameterization of BCM ECU) with following steps a. Turn the IGN ON again and Unlock security to BCM ECU. b. Perform the parameterization as per vehicle variant with the help of diagnostic tool. c. Power Latch - Ignition->OFF->ON transition. (Make sure is key is taken out). d. Read and confirm configuration data from BCM against server. 17.Read the DTCs and clear all the DTCs from BCM ECU with the help of diagnostic tool. 18.Provide IGN off-on cycle. 19.Read the DTCs from BCM ECU with the help of diagnostic tool. If any DTC is present follow the respective troubleshooting procedure to rectify it. 20.Execute Service Test Routine for BCM ECU a. Execute BCM EOL Self-test routine (31 01 20 01) b. Read the DTCs from BCM ECU with the help of diagnostic tool. If any DTC is present follow the respective troubleshooting procedure to it. c. Execute Input switch test routine (31 01 34 09 06) d. Read Input switch test routine results with the help of diagnostic tool. If any DTC is present follow the respective DTC troubleshooting procedure to rectify it. MAJOR PRECAUTIONS FOR REPLACEMENT 1. While replacing the BCMs, it is suggested not to touch the BCM pins with hand. 2. While tightening the screws, tightening torque must not exceed 3. BCM upper and lower covers shall not be removed while verifying/replacing the BCM. 4. All of the service tool instructions for BCM replacement shall be followed.
