Good day!
I have some problems using Nefmoto's software. Here are them:
Connecting...
Starting slow init connection.
Connecting to address 0x01.
Slow init succeeded.
Switching to KWP2000 session.
Sending start communication request.
Connected
Disabling Windows sleep mode.
Reading ECU flash memory.
ECU reports programming session preconditions have been met.
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
Security access granted.
Starting diagnostic session.
Successfully started diagnostic session.
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
Security access granted.
Validating flash memory starts at 0x00800000 and ends at 0x00900000.
Validation failed, ECU reports that security access is not granted.
Memory layout validation failed.
Starting to read data block.
Calculating flash checksum to determine if reading is necessary for range: 0x00800000 to 0x00804000
Flash checksum does not match, reading flash data is necessary.
Requesting upload from ECU for address range 0x00800000 to 0x00803FFF.
Request upload from ECU failed, ECU reports security access has not been granted.
Reading ECU flash memory failed. Trying to force ECU to recognize read operation is complete.
Finished forcing ECU to recognize that failed read operation is complete.
Reading ECU flash memory failed.
100% complete.
Restoring Windows sleep mode.
Can't read full flash.
Ecu's info:
0x92, System Supplier ECU Hardware Number: 0261207939,
0x94, System Supplier ECU Software Number: 1037366883,
0x91, Vehicle Manufacturer ECU Hardware Number: 0x0D, 8E0909018A , 0xFF,
0x9B, Calibration Date: 8E0909518AF , 0003, 0x0300416F, 0x00000000, 0xF777, 1.8L R4/5VT , G ,
0x9C, Calibration Equiment Software Number: 0x00000000,
Any suggestions how to solve the problem? I tried playing with baud rates, changing memory layouts but no luck.
Tried to search on forums, all i found is "already tuned ecu" situation. But it doesn't seem so. Well, who knows..
