Because both A/T and M/T fuel control map is inputted in one type of ECM and selecting option is possible, one type is applied to both A/T and M/T option.

When ECM is installed to vehicle, A/T and M/T recognition is performed by ECM automatically as checking whether ground line(ECM connector CUD-K terminal 81) is grounded or opened.(A/T and M/T recognition is performed every IG KEY ON process.)

If A/T, M/T recognition is not fulfilled well or any error occurs during the process, engine power generation is not sufficient and glow lamp on cluster blinks.

A/T : ECM connector CUD-K terminal 81 is grounded

M/T : ECM connector CUD-K terminal 81 is opened(no wiring exists)

P1588 is set when the signal from A/T, M/T auto recognition terminal(ECM CUD-K terminal 81) changes during engine run. This code is due to open in terminal for A/T option, grounded condition for M/T option. This code is normally arises from A/T option vehicle. Check the grounding condition of A/T, M/T auto recognition terminal.
