Symptoms

  • MIL illuminated
  • Symptoms depend on the affected internal function

Possible causes

  • Internal control module hardware fault
  • Control module supply voltage or ground fault
  • Software/coding fault after programming
  • In rare cases, interference from wiring faults

Recommended checks

  • Check control module power supplies and grounds first
  • Check battery condition and charging voltage
  • Verify software version and check OEM bulletins
  • Clear the code and retest under the original conditions
  • Only after supply-side checks, consider module assessment
