The ECM is logging a fault. THROTTLE malfuction is minor....a cmd fault. Its being stored for the tech back at the shop. Do not try to clear it. Keep Running unless the truck becomes unsafe to drive. The Freightliner shop can clear all the faults when doing a routine pm and advise you what happened.
You should log date and time the fault happened so you can reference to it if it continues...It may even clear itself by restarting the engine.Last edited: Jul 12, 2020

From your picture, it looks like you have an ICU4M, and it is stating the ENG[ine] 2 (aka, MCM), SPN 3464 FMI 31. (I'm guessing you have an EPA 10 DD15 since you did not specify vintage of DD15...)
352.4 SPN 3464/FMI 31 - EPA10 - GHG14
Intake air throttle control electrical fault
SPN 3464/FMI 31
Description Intake Air Throttle Control Electrical Fault
Monitored Parameter Intake Throttle Valve
Typical Enabling Conditions Key On & Engine Off
Monitor Sequence None
Execution Frequency Continuous when enabling conditions met
Typical Duration 2 Seconds
Dash Lamps MIL, CEL
Engine Reaction Derate 10%
Verification Engine OFF, then 1 minute idle
Looks like pin 4 and pin 5 of the Intake Throttle Valve harness needs to be checked. Check pin 5 to ground and pin 4 to pin 100 of the MCM 120 pin connector. Post your results.OldiM and QUALITYTRUCK Thank this. -
