This error code, AIC 520425.07, is triggered when the error counter for the vehicle’s CAN (Controller Area Network) Bus in the Armrest Interface Control Unit (AIC) reaches an unusually high level. Such a condition typically indicates persistent communication errors within the CAN Bus, which may be caused by electrical noise, faulty connections, or incompatible devices…

This code, AIC 520286.11, is issued when the set rear hitch lower setpoint button on the armrest hitch controls module remains in a pressed condition for an extended period, combined with a detected fault in the quick raise/lower switch. These symptoms suggest a defective switch, which may be stuck, malfunctioning, or experiencing internal degradation, impacting…

This error code, AIC 520286.04, indicates that the output voltage from the armrest hitch controls module is abnormally low, with sensor input voltage falling below 0.5 volts. This significant drop typically points to a short to ground within the module’s circuitry, which can disrupt normal operations and potentially damage the system.

This error code, AIC 520286.02, is generated when the set rear hitch lower setpoint button on the armrest hitch controls module malfunctions. The fault prevents the button from performing its intended function, which could be due to an electrical issue, a mechanical failure, or software problems affecting the button’s operation. A temporary system recovery can…

This error code, AIC 520285.02, identifies a fault within the armrest hitch controls module, specifically with the rear hitch lock button. The button is not operating as intended, which might be due to electrical issues within the module, a faulty button mechanism, or disruption in the circuit connectivity. This kind of fault can impede the…

This diagnostic trouble code, AIC 520257.02, is triggered when incorrect logic is detected at the Auto Mode switch. This condition typically suggests a malfunction in the switch itself or in the associated circuit, possibly due to a faulty component, incorrect wiring, or wear and tear. Such issues can disrupt the normal functioning of systems that…

This error code, AIC 516461.02, arises when there is a conflict between the detent switch of the SCV XV (Selective Control Valve XV) control lever and the lever’s actual position. This discrepancy indicates an issue with either the switch’s sensitivity or the lever’s feedback mechanism, which may result in incorrect signal processing. Such conflicts typically…

This code, AIC 516446.09, is generated when the Armrest Interface Control Unit (AIC) fails to receive a LIN message from the armrest multi-function lever module. This failure indicates a data transfer issue between the AIC control software and the LIN Bus module, specifically at positions F and G. The absence of this crucial communication could…

This code, AIC 516317.06, indicates an overcurrent condition in the 12V sensor supply 2 of the Armrest Interface Control Unit. The high current is typically due to a short to ground, which could result from damaged insulation, exposed wiring, or faulty electrical connections. Such conditions are not only detrimental to the electrical system’s integrity but…
