RE: Acura87, đèn báo phun xăng điện tử sáng.
Tui thấy Flash code hướng dẩn cũng khá rỏ , Bác thử nghiên cứu lại xem sao . Bác chịu khó dịch hộ nhé
86-94 Acura
The Engine Control Unit (ECU) stores trouble codes. On the outside of the ECU case are one or two LEDs. If the ECU has 2 LEDs, ignore the Amber LED and look at the Red LED. On 87-89 models, the ECU is located beneath the front passenger seat. 1990-1994 models locate the ECU under the dashboard on the passenger's side beneath the carpet. Legend models provide a flip-out mirror that allows you to view the LEDs. Earlier models have a "window" at the base of the passenger front seat that allows you to view the LEDs.

The Check Engine light will illuminate when the ECU stores a trouble code.
Counting the Flashes
To retrieve trouble codes, turn the ignition key to the "on" position with the engine off.
86-89 models:
The ECU will flash many short blinks. The total number of blinks equals the code number. For example, 12 short blinks equals code 12, nine short blinks equals code 9, etc.. If more than one code is stored, the ECU will flash the codes in sequence (lowest to highest) with a pause between each code. The codes will repeat until the key is turned to the OFF position.
90-94 models:
The ECU will flash a long blink to represent the first digit of the code, then a series of short blinks to represent the second digit. For example, 1 long blink, followed by 4 short blinks equals code 14. Four long blinks followed by five short blinks equals code 45.
NOTE: Legend Models: If code 7 or 17 is stored and the S4 light on the transaxle indicator panel is also flashing, it may be necessary to diagnose the automatic transaxle control unit.
86–90 Legend & 86–91 Integra
In the event of a PGM-FI system malfunction, the engine warning lamp will light and stay lit. When this condition occurs, it will be necessary to inspect the ECU LED display. On Integra models, the ECU contains a single red LED display. On Legend models, the ECU contains a red and a yellow LED display. The red LED should be used for both models when diagnosing PGM-FI system malfunctions.
When the engine warning lamp is illuminated, proceed as follows:
On all models except 1991 Integra, move front passenger seat to rear position.
On 1991 Integra models, pull down passenger side carpet from under dashboard.
On all models, turn ignition On and observe red LED on front or top of ECU. The LED will indicate diagnostic trouble codes (DTCs) by number of flashes.
