Value
Subsystem
10 No communication with auxiliary CPU (auxiliary CPUin boot loader
mode)
20 Main and auxiliary CPU firmware mismatch
IO - ECU input/output flags
These digits identify faults in the ECU inputs and outputs.

01 Input capture over frequency
12.2.5. Decoding error codes
These examples show how to decode the error codes using the
signature.
Example 1
This example applies to both the CM-40 and EM-24.
IOGGPPDDEE = Error signature
0000010004 = Error displayed (10004 is displayed in Sunrise)
The displayed error is split across three values in Universal Terminal
mode, these should be joined.
Align the last digit of the displayed error with the last digit of the
signature.
Note that leading zeros (green) are not displayed when using Sunrise
and should be added.
Signature digits Decoded error
EE = 04 The power subsystem has a high severity fault
DD = 00 The drive subsystem does not have any errors
PP = 01 Specific fault in this case is:
Solenoid power under voltage
GG = 00 There are no general errors
