TuningBot DTC Database · v4.37.15
12 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.
FordThe control module registered the fault condition described as "Idle Air Control Under Speed Error". This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected that the Idle Speed Control Actuator signal stayed below the expected range. This is the manufacturer-specific definition used by Hyundai.
JaguarThe control module detected that the Idle air control (IAC) valve - RPM value was higher than expected for the current conditions. This is the manufacturer-specific definition used by Jaguar.
KiaThe control module detected that the Idle air control (IAC) valve - closing coil signal stayed below the expected range. This is the manufacturer-specific definition used by Kia.
Land RoverThe control module detected a fault associated with the Idle air control (IAC) - value low circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected a fault associated with the PTC AC Auxiliary Heater Disabled Low circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Lexus.
MazdaThe control module registered the fault condition described as "Idle air control (IAC) system - underspeed error". This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected that the Idle Speed Control Valve Open Solenoid Control signal stayed below the expected range. This is the manufacturer-specific definition used by MINI.
MitsubishiThe control module detected that the Idle air control (IAC) valve - RPM value was higher than expected for the current conditions. This is the manufacturer-specific definition used by Mitsubishi.
SubaruThe control module detected improper operation of the Idle air (IAC) control system. This is the manufacturer-specific definition used by Subaru.
VAGThe control module detected that the Idle speed control (ISC) value was below the expected limit. This is the manufacturer-specific definition used by Audi.
The control module detected that the monitored Idle Control Sys: Lower Regulation value reached its permissible limit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17915. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
