Not sure why you would post that as a scan issue. Your fault code is because the machine got set for the wrong speed, so you have a 560 that is being told to run as a 550 or vice versa.
124-315 RAP
IOT Speed Mismatch
Procedure
CAUTION
The Accessories have their own power cord. Whenever a procedure states to Power Off and
then Power On, POPO, etc., powering Off and then powering On the IOT does NOT Power Off
the Accessory. The Accessory will have to be Powered Off and then On separately from the
IOT by unplugging the Accessory power cord.
Switch the power Off then On. If the problem still exists, perform the following:
Enter NVM Read/Write. Check the values at the following Chain Link Codes.
• NVM Read/Write [700-600] (IOT):
• NVM Read/Write [700-601] (SYS 1):
• NVM Read/Write [700-602] (SYS 2):
The three values are all different.
Y N
Perform GP 4 Serial Number Synchronization Procedure.
• Replace the MCU PWB (PL 11.1).
• If the problem continues, replace the ESS PWB (PL 11.6).
NOTE: IOT refers to MCU PWB, SYS 1 to ESS NVM PWB, and SYS 2 to ESS PWB.
You are going to need a tech to resolve it, or find a service manual and do lots of reading.
