Sharp AL2080 Error Codes List page 4 from 4

  • Code: L4-11
  • Description: Shifter motor trouble
    The shifter home position detection signal is not detected when initializing the shifter.
  • Causes: Shifter motor abnormality, improper connection or disconnection of the harness, shifter home position sensor abnormality
  • Remedy: Use SIM 03-11 to check the shifter motor operations. Check connection of the harness/connector of the shifter motor. Replace the shifter motor. Replace the MCU PWB.
  • Code: L6-10
  • Description: Polygon motor lock detection
    The polygon motor does not rotate. The motor lock signal is detected for 6sec after rotation of the polygon motor. The motor lock signal is detected for 1sec during rotation of the polygon motor.
  • Causes: Polygon motor unit abnormality Improper connection or disconnection of the polygon motor and the harness. MCU PWB abnormality
  • Remedy: Use SIM 61-1 to check the polygon motor operations. Check connection of the polygon motor harness/connector. Replace the polygon motor.. Replace the MCU PWB.
  • Code: L8-01
  • Description: No full wave signal
    The zero cross signal is not detected.
  • Causes: Power unit abnormality MCU PWB abnormality
  • Remedy: Check connection of the harness and connectors. Replace the MCU PWB. Replace the power unit.
  • Code: U2-04
  • Description: EEPROM read/write error (Serial communication error)
