Honda Ascot OBD Check Engine Cracking


Honda Ascot OBD Check Engine Cracking

The Honda Ascot is a compact sedan manufactured by Honda and marketed only in Japan from 1989 to 1997. The first generation produced two versions based on the Honda Accord CB series called the Ascot and from 1993 to 1996 a “pillared hardtop” called the Ascot Innova. The Innova shared much of its mechanicals with the European-market Accord manufactured at the Honda UK facility in Swindon, England, and was essentially the badge engineered Rover 600. The second generation was a platform improvement, shared with the Japan-only sedan called the Honda Rafaga. The “Ascot” name was chosen with reference to the Ascot Racecourse and Ascot tie, in order to add the model an alleged air of class and elegance.

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.

READING CODE INSTRUCTION
• 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.
