This diagnostic trouble code, TSC 523974.03, is triggered when the TSC (TLS front-wheel drive axle) detects too high a voltage (more than 4.75 volts) at the signal output of the TLS oil pressure sensor (B167).

This diagnostic trouble code, TSC 523974.02, is triggered when, during the TLS oil pressure sensor check, the TSC (TLS front-wheel drive axle) detects an incorrect change in pressure (a reduction in pressure instead of an increase, or vice versa).

This diagnostic trouble code, TSC 523973.31, is triggered when the TSC (TLS front-wheel drive axle) fails to reach its level position within 60 seconds while traveling at speeds above 10 km/h (6 mph).

This diagnostic trouble code, TSC 523973.04, is triggered when, during operation/calibration, the TSC (cab suspension) detects too low a voltage (less than 0.25 volts) at the signal output of the cab position sensor (B110) when the cab suspension is at its bottom position.

This diagnostic trouble code, TSC 523972.13, is triggered when, at the end of calibration, the TSC (cab suspension) detects a level position voltage that is out of range (i.e., not between 2 and 3 volts).

This diagnostic trouble code, TSC 523972.03, is triggered when, during calibration, the TSC (cab suspension) detects too high a voltage (more than 2 volts) at the signal output of the cab position sensor (B110) when the cab suspension is at its bottom position.

This diagnostic trouble code, TSC 523965.31, is triggered when manual leveling of the suspended front axle is activated, and the TSC (TLS front-wheel drive axle) fails to achieve the necessary pressure (90 bar / 9000 kPa / 1305 psi) and the level position is not reached within 30 seconds. Potential causes include: A problem in…

This diagnostic trouble code, TSC 523964.06, is triggered when the control unit measures too high a current at the signal input of the solenoid valve for reducing TLS (Total Lubrication System) pressure (Y68). This indicates a short to ground in the circuit.

This diagnostic trouble code, TSC 523964.05, is triggered when the control unit measures too low a current at the signal input of the solenoid valve for reducing TLS pressure (Y68). This indicates that the circuit is either shorted to a supply lead or is open.

This diagnostic trouble code, TSC 523951.15, is triggered when the TLS front-wheel drive axle does not reach its bottom position within 60 seconds in the pressure relief mode. Potential causes include: A problem in the circuit of the TLS position sensor (B53). A problem in the circuit of the TLS pressure reduction solenoid valve (Y69).…
