Honda Aerodect Obd cracking even without OBD tools
PLEASE SELECT THE OBD SOCKET OF YOUR CAR BELOW AND FOLLOW THE JUMPER SETTINGS.
Year range: 1989 to 2001 Locations: Under the passengers seat. | Year range: 1998 to 2009 Locations: Under the drivers side dash panel. |
PLEASE NOTE:If after following the instructions below the Check Engine Light does not flash it either means there are no fault codes or there is a connection error. To test connection, remove the TPS and run the engine then recheck codes.
INSTRUCTION:
1. If possible run the engine to bring the oxygen sensor up to operating temperature then switch the engine off.
2. Connect the terminals using your own jumper wire, as shown in the diagram above.
3. Turn ignition ON, the Check Engine Light (CEL) should be flashing on your car dashboard.
4. Read codes as described in the Code Format Description below.
Code Format Diagram
• Each code is made up of two series of flashes.
• The long flashes indicate the ‘tens’ digits.
• The short flashes indicate the ‘ones’ digits.
• A long pause separates each code sequence.
• Code Format Diagram shows above is code No. 12.
• If nolongflashes are observed then the code is a straight count of short flashes. i.e. 4 flashes = code 4.

Erasing procedure.
- After the faults have been rectified, trouble codes can be erased by using a Scan Tool connected to the data link connector (DLC) or as follows:
- Switch ignition OFF.
- Remove radio fuse (7.5A) from underhood fusebox for 10 seconds minimum
- Reinstall fuse.
- Repeat checking procedure to ensure no data remains in ECM fault memory.
