Honda Honda 90-93 Accord 2.2L Trouble Code Info

General Information

  • Trouble codes can be displayed by LED in engine control module (ECM) – 1990 or malfunction indicator lamp (MIL) – 1991-93.

Accessing Trouble Codes

  • Ensure ignition switched OFF
  • Jump service check connector terminals Image 1
  • 1990 – access engine control module (ECM) Image 2
  • Switch ignition ON.
  • Check ECM LED is flashing.
  • 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
  • Switch ignition OFF
Scan0015 Scan0014

Clearing Trouble Codes

  • After the faults have been rectified, erase the trouble codes as follows:
  • Ensure ignition switched OFF
  • Remove fuse No.24 (7.5A) from underhood fusebox for 10 seconds minimum
  • Reinstall fuse
  • Repeat accessing procedure to ensure no data remains in ECM fault memory
