Description:

This error code, SCO 000924.03, indicates that the supply voltage (BAT) for the stepper motors of E-SCV X and E-SCV XI has risen above 16 volts. Excessive voltage can damage electronic components and disrupt the operation of the stepper motors.

Reaction:

When this fault is detected, the control software will have limited or no function of the selective control valves (E-SCVs).

Recommendations:

• Inspect Charging System:
  • Ensure that the charging system, including the alternator and voltage regulator, is functioning correctly. Replace any faulty components.
• Check for Overvoltage Conditions:
  • Investigate any possible causes of overvoltage, such as external charging sources or malfunctioning equipment.
• Test Electrical Components:
  • Test other electrical components for signs of damage due to overvoltage and replace as necessary.
• Monitor Voltage:
  • Continuously monitor the supply voltage to ensure it stays within the recommended range.

Note:

Preventive Maintenance:

• Regular maintenance and inspection of the charging system can help prevent overvoltage conditions and protect the control software and stepper motors.
