86-87 Accord and Prelude
ECU Location
The ECU is located under the driver's seat. With the ignition switch in the "on" position and the engine OFF, the red LED on the ECU will flash the trouble codes. For example, 2 flashes, pause, 3 flashes would mean code 23. Codes are displayed in ascending order.

ECU Location
The ECU is located behind the passenger's side kick panel.
88-91 Civic, Accord, and Prelude
Retrieving Codes
When the CHECK ENGINE warning light has been reported on, turn the ignition ON, pull down the passenger's side carpet inspection flap from under the dashboard, and monitor the LED on the top of the control unit. The LED indicates a system failure code by its blinking frequency.
The control unit LED can indicate any number of simultaneous component problems by blinking separate codes, one after another.
If codes other than those listed are indicated, count the number of blinks again. If the indicator is in fact blinking these codes, substitute a known good ECU and recheck. If the indication goes away, replace the original ECU.
The CHECK ENGINE warning light and control unit LED may come on, indicating a system problem, when in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair connections if necessary.
92-95 Accord, Civic, Civic Del Sol and Prelude
Retrieving Codes
With ignition off, insert jumper wire in service check connector terminals, located behind right side of dash on Accord, Civic and Civic Del Sol and near center console on Prelude.
Turn ignition switch to ON position. Diagnostic Trouble Codes (DTCs) will be indicated by a series of long and short flashes on MIL.
The number of long flashes indicates the number in the 10s column. The number of short flashes indicates the number in the 1s column. For example, 4 long flashes followed by 3 short flashes would indicate DTC 43.

Clearing Codes
Disconnect the negative battery cable for at least 10 seconds to clear codes.
Accord, Civic, CRX, CR-V, del Sol, Odyssey & Prelude
PGM-CARB
If the PGM-CARB warning lamp is lit, turn ignition On, pull passenger side carpet inspection flap downward under instrument panel and observe LED on top of control unit. The LED indicates a system failure by its blinking frequency.
The control unit LED can indicate any number of simultaneous component conditions by blinking separate codes, one after another.
If DTCs 7, 9, 11, 12, 13 or any higher than 14 are indicated, count the number of blinks again. If the indicator is in fact blinking these DTCs, substitute a known good control unit and inspect again. If indication goes away, replace the control unit. The PGM-CARB warning lamp and control unit LED may light, indicating a system problem when, in fact, there is a poor or intermittent electrical connection. Clean or repair connections as required.
PGM-FI Exc del Sol, Odyssey, 90–98 Accord, 90–91 Prelude 2.1L,
92–98 Prelude & 91–98 Civic
In the event of a PGM-FI system electrical malfunction, an instrument panel mounted indicator lamp will light and stay lit. If the lamp is on, or if a system malfunction is suspected even though the lamp is off, it is necessary to inspect the electronic control unit LED display. The LED display is on the ECM (ECU), which is located just below the RH side of the instrument panel. The indicator lamps operate whenever the ignition is On and a DTC is stored in the ECM (ECU) memory.
When an abnormality is detected the ECM (ECU) display blinks. The LED blinks a certain number of times, with the number of blinks indicating the number of the DTC. After the LED blinks a number of times there will be a two second pause and the LED will blink out the number of the next DTC.
90–95 Accord Four Cylinder, 90–91 Prelude 2.1L, 92–95 Prelude & 91–95 Civic
If the malfunction indicator/Check Engine lamp remains lit or lights while the engine is operating, the ECM has detected a malfunction and has stored a DTC in its memory. To access the DTC memory, connect a jumper wire between the check connector terminals. On Accord and Civic models, the check connector is located under the RH side of the instrument panel. On 90–91 Prelude models equipped with 2.1L engine, the check connector is located in the engine compartment. On 92–95 Prelude models, the check connector is located in the passenger compartment behind the center console.
On all models, turn the ignition On. The ECM indicates stored DTCs by flashing the malfunction indicator/Check Engine lamp. DTCs one through nine are indicated by individual short blinks. DTCs 10 and above are indicated by long and short blinks. One long blink is equivalent to 10 short blinks. The DTC can be determined by adding the long and short blinks.
