When viewing fault codes with OP COM you often get a 4 digit fault code followed by 2 digits. Until now the description of the 2 digits has been unknown. Here are the descriptions of the 2 digit codes.
Also valid for opcom dtc descriptions and pedal test ECN 6 digit codes.

Hi pictorino,

Just a small note on this one.
The last 2 digits are failure type sub-codes.

"All EOBD codes may have an additional 2 characters following the main trouble code which indicates the type of failure,
e.g. P0058-XX, where 'XX' equals the failure type code."

00 No failure type information
01 General electrical failure
02 General signal failure
03 Frequency modulated (FM)/pulse width modulated (PWM) signal failure
04 System internal failure
05 System programming failure
06 Algorithm based failure
07 Mechanical failure
08 Data bus signal/message failure
09 Component failure
11 Short circuit to earth
12 Short circuit to positive
13 Circuit open
14 Open circuit/short to earth
15 Open circuit/short to positive
16 Circuit voltage below threshold
17 Circuit voltage above threshold
18 Circuit current below threshold
19 Circuit current above threshold
1A Circuit resistance below threshold
1B Circuit resistance above threshold
1C Circuit voltage out of range
1D Circuit current out of range
1E Circuit resistance out of range
1F Circuit intermittent
21 Signal amplitude below minimum
22 Signal amplitude above maximum
23 Signal stuck low
24 Signal stuck high
25 Signal shape/waveform failure
26 Signal rate of change below threshold
27 Signal rate of change above threshold
28 Signal bias level out of range/zero adjustment failure
29 Signal invalid
2A Signal stuck in range
2B Signal cross-coupled
2F Signal erratic
31 No signal
32 Signal low time below minimum
33 Signal low time above maximum
34 Signal high time below minimum
35 Signal high time above maximum
36 Signal frequency too low
37 Signal frequency too high
38 Signal frequency incorrect
39 Signal has too few pulses
3A Signal has too many pulses
41 General checksum failure
42 General memory failure
43 Special memory failure
44 Data memory failure
45 Program memory failure
46 Calibration/parameter memory failure
47 Watchdog/safety micro-controller failure
48 Supervision software failure
49 Internal electronic failure
4A Incorrect component installed
4B Over-temperature condition
51 Component not programmed
52 Component program not activated
53 Component program disabled
54 Missing calibration
55 System not configured
56 Invalid/incompatible configuration
57 Invalid/incompatible software component
61 Signal calculation failure
62 Signal comparison failure
63 Circuit/component protection time-out
64 Signal plausibility failure
65 Signal has too few transitions/events
66 Signal has too many transitions/events
67 Signal incorrect after event
68 Event information
71 Actuator stuck
72 Actuator stuck open
73 Actuator stuck closed
74 Actuator slipping
75 Emergency position not reachable
76 Incorrect mounting position
77 Commanded position not reachable
78 Alignment or adjustment incorrect
79 Mechanical linkage failure
7A Fluid leak or seal failure
7B Low fluid level
81 Invalid serial data received
82 Alive/sequence counter incorrect/not updated
83 Value of signal protection calculation incorrect
84 Signal below allowable range
85 Signal above allowable range
86 Signal invalid
87 Missing message
88 Data bus off
8F Signal erratic
91 Component parameter out of range
92 Performance problem/malfunction
93 No operation
94 Unexpected component operation
95 Incorrect assembly
96 Component internal failure
97 Component or system operation obstructed or blocked
98 Component or system over-temperature condition
9A Component or system operating condition

so this means that if you have for example P0AE3-72

Will mean: P0AE3-97 Hybrid battery precharge conductor circuit stuck open - Actuator stuck open (meaning that there is some sort of relay stuck to open position and circuit for the conductor of the hybrid battery is not closed (forming a closed circuit) )

Also U faults are not unidentified faults but communication error codes.
So, for example U010F AC control module communication signal lost.
Also keep in mind that not all U codes will tell you faults for communication with CAN for example or other communication protocols. There are other ways of checking the "communication" of a system, e.g. U3001 Control unit improper shut down. (means that a communication issue was cause because control unit did not shut down/power off/sleep mode properly)


Hope this will help someone figure out what codes are trying to explain.

Cheers,
the metalhead.

Does anyone knows what indicate number 10?

See the above numbers again, and watch closely.  
Do you see a pattern in the numbers?
