Description:

This error code, SCO 000926.03, indicates that the supply voltage (BAT) for the stepper motor of E-SCV XIII has risen above 16 volts. Excessive voltage can damage the stepper motor and prevent it from functioning correctly.

Reaction:

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

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 stepper motor.
