HARRIER SERVICE MANUAL PART -1

ELECTRICAL 196 2. BCM shall erase the paired keys data from memory, whenever this routine is initiated by the EOL/Service tool to BCM. 3. BCM shall store temporarily the number of keys to be paired in routine request and shall compare every time before each key pairing is started till the requested no. of keys in the start routine and the pairing request keys through Lock and Unlock press. If BCM receives number which is not valid then it update the same as “0x00 -- Not paired” in routine results response to the tool and exit from the routine. Tool shall read the same and update in the display to the users ‘ key learning failed ’ and shall stop further actions. 4. Tool should display ‘ please press LOCK and UNLOCK buttons together on 1st remote ’ and should wait for timeout (time requested in start routine for each key pair), after successful pairing process Tool should display ‘ please press LOCK and UNLOCK buttons together on 2nd remote ’ and should wait for timeout and then upon routine results request BCM update and set the additional data accordingly as mentioned in routine response additional data table. Time required for pairing is default 5sec, it is configurable between min. 2sec and max. 20sec 5. Routine result response additional data - Byte 1 – a) BCM shall update this byte “Keys Not paired (0x00)”, till all keys paired and routine executed successfully. If BCM is in continuation of routine execution process then it shall update this byte as 0x00 upon routine result response from tool (i.e., 71 03 34 0E 04(RS) 00 00), and Tool shall again request the same after some time. 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,
