Honda Honda 92-95 Civic 1.5/1.6L & 92-95 Prelude 2.2/2.3L Trouble Code Info

General Information

  • Trouble codes are displayed by the malfunction indicator lamp (MIL)
  • Engine control module (ECM) incorporates self-diagnosis function

Accessing Trouble Codes

  • Ensure ignition switched OFF
  • Join together the service check connector terminals Civic Image 1 [1] Prelude Image 1 [2]
  • Switch ignition ON.
  • MIL should flash
  • Trouble codes 1-9 are indicated as follows:
    • Individual short flashes display trouble code
    • A short pause separates each flash
    • A long pause separates each trouble code
  • Trouble codes greater than 9 are indicated as follows:
    • Long flashes indicate the ‘tens’ of the trouble code
    • Short flashes indicate the ‘units’ of the trouble code
    • A short pause separates each flash
    • A long pause separates each trouble code
  • Count MIL flashes and compare with trouble code table below
  • Switch ignition OFF
  • Disconnect the service check connector terminals

Clearing Trouble Codes

  • After the faults have been rectified, erase the trouble codes as follows:
  • Ensure ignition switched OFF
  • Civic – remove fuse No.32 (7.5A) from underhood fusebox for 10 seconds minimum
  • Prelude – remove fuse No.43 (10A) from underhood fusebox for 10 seconds minimum
  • Reinstall fuse
  • Repeat accessing procedure to ensure no data remains in ECM fault memory
