This error code, AIC 523745.11, signals a fault with the iTEC™ program selection switch, specifically that it has been pressed for an excessively long period. This prolonged activation typically indicates that the switch may be stuck or contaminated with debris, preventing it from returning to its neutral position after being engaged.

This error code, AIC 523745.04, indicates that the voltage at the iTEC™ program selection switch is abnormally low, suggesting a potential issue such as a faulty switch, a short to ground, or a problem within the electrical circuitry associated with the switch. Low voltage can affect the switch’s ability to function properly and reliably communicate…

This error code, AIC 523745.03, is triggered when the voltage at the iTEC™ program selection switch is detected to be excessively high, potentially indicating a faulty switch or a short circuit within the switch’s electrical circuitry. High voltage in this context could damage the switch, disrupt its functionality, or pose a safety risk due to…

The error code AIC 523745.02 identifies a fault within the iTEC™ program selection switch, specifically regarding the logic of sequences 1 and 2. Incorrect switch logic suggests that the switch may not be functioning as designed, possibly due to a faulty switch mechanism or an issue within the electrical circuitry handling these inputs.

This error code, AIC 523671.13, indicates a problem with the calibration of the shift lever system, either because the calibration is outside the maximum allowable range or because a failed calibration attempt was saved. This misalignment or error in calibration settings can lead to inaccurate shift lever operations and potentially unsafe transmission responses.

This error code, AIC 523671.11, pertains to a malfunction in the shift unit of a DirectDrive transmission system, where the position of the shift lever cannot be accurately determined. This uncertainty prevents the control system from confirming whether the transmission is in the correct gear or position for safe operation.

This error code AIC 523671.07 signals a fault related to the mechanical response or adjustment of the drive lever. It indicates that the mechanical system linked to the lever operation is either not responding as expected or is improperly adjusted, which could affect the proper engagement and disengagement of the drive system.

This error code AIC 523671.02 identifies a conflict within the drive lever circuit, specifically related to an error in the forward slot position of the right-hand reverser. This indicates a misalignment or malfunction in the sensors or mechanisms that detect the lever’s position, potentially leading to incorrect or unsafe transmission behavior.

READ MORE

The error code AIC 523670.11 is triggered when the vehicle is started while the drive lever is in either a gear increase position or a gear decrease position. This situation is not typical for standard operational procedures and indicates that the drive lever was not in a neutral position at startup, which could lead to…

The error code AIC 523670.02 identifies a signal mismatch within the speed control system of the tractor. Specifically, there is a conflict between the signal from the switch for speed band 2 and the signal from the potentiometer of the speed control lever. Although the switch for speed range 2 is activated, the lever position…

This error code AIC 523652.09 indicates a communication failure where the Armrest Interface Control software (AIC) is not receiving the necessary LIN message from the Armrest Engine Speed Control Module. The issue has been pinpointed to a data transfer problem between the AIC and the LIN Bus at position H, suggesting either a malfunction within…
