SCO 000926.03 – Stepper Motor for E-SCV XIII, Supply Voltage Too High

SCO 000926.03 (SCO 926.03)

Code: 000926.03

Shortcode: 926.03

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.
