[Ovmsdev] DTC code reading

Mon Jun 21 14:41:19 HKT 2021

Now i create a new log file without dropped frame, with filter.
https://drive.google.com/file/d/1o477jmllYyntpmLJca_3aTmL2NvYZfsZ/view?usp=sharing

Only active error code is U1113.

This is a U1113 Error?
1624253728.207555 1R11 751 04 18 00 ff 00 00 00 00
1624253728.213037 1R11 752 05 58 01 d1 13 e0 00 8e

OVMS# obd can1 request device 751 752 1800ff00
751[752] 1800ff00: Response: 01 d1 13 e0                 | ....
if i decode this
d1 = 11010001
bit 6-7 = 11 -» U
bit 4-5 = 01 -» 1
bit 0-3 = 0001 -» 1
 so the error code is: U1113

OVMS# obd can1 request device 751 752 1801ff00

This is clear of dtc codes?
