Accord 5th Gen 94-97 DTCs
written by: 98CoupeV6

[SPOILER="click here to view"]
This thread will list the DTCs (diagnostic trouble codes) with a brief description of it. To receive a more in depth explanation of the code and/or troubleshooting methods, please search the forum for that code or ask in my TSB/tech question thread.

I HAVE A CHECK ENGINE LIGHT OR SRS LIGHT; HOW DO I FIND OUT THE TROUBLE CODE? For 6th gens, you'll have to either bring the car to the dealer and for $60 they'll tell you and diagnose it or you can bring it to an Autozone or similiar and they'll hook up an OBDII reader to your car for free and grab your code. However, there is a special shortcut you can take to eliminate the need to start your car up:

Reading Check Engine Codes

1) Jumper the service connector
2) Turn the ignition key to ON
3) Count the flashes on the instrument panel
4) Look up what the code means

The flashes will be a series of long blinks, a pause, followed by short ones. For example:

Long-Long-Long-Long-Long-Long-Long____ShortShort

7 long and 2 short, indicates a code 72.





The 'MIL indication' column refers to the number of times the CEL blinks when you insert the paper clip into the connector. It is not uncommon to get multiple codes, so be careful and write them down.

Clearing Trouble Codes



1) Remove the Back up fuse for 10 seconds.

How to Clear ABS Codes

Remove the Anti-lock Brake System (ABS) B2 (15 A) fuse in the under-hood ABS fuse/relay box for at least three seconds to erase the ABS control unit's memory.
The memory of the Diagnostic Trouble Codes (DTC) is erased when the connector is disconnected from the ABS control unit.

4th Gen Diagnostic Trouble Codes (DTC)
written by: 98CoupeV6

[SPOILER="click here to view"]
This thread will list the DTCs (diagnostic trouble codes) with a brief description of it. To receive a more in depth explanation of the code and/or troubleshooting methods, please search the forum for that code or ask in my TSB/tech question thread.

I HAVE A CHECK ENGINE LIGHT, ABS SRS LIGHT; HOW DO I FIND OUT THE TROUBLE CODE? For non-OBDII 4th gens, you'll have to bring the car to Honda or follow the following procedure:

EXTRACTING FAULT CODES:

If the "CHECK" engine light has been reported on, you can extract the fault codes as follows:

1) Turn the ignition on.
2) Pull down the passenger side carpet from under the dashboard to access the ECU.
3) Observe the LED on top of the ECU.



4) The LED indicates a fault code by the blinking frequency. The LED can indicate multiple fault codes by blinking separate codes one after another.
Fault codes 1 through 9 are indicated by individual short blinks.
Fault codes 10 through 43 are indicated by a series of long and short blinks. One long blink equals ten short blinks.
Add the long and short blinks together to determine the fault code.



5) By connecting the two terminals of the check connector (located on passenger side under dashboard) with a jumper wire, the "CHECK" engine light will flash the same fault code(s) as the ECU LED. Don't forget to remove the jumper wire when you are done extracting the fault code(s).
6) Note the fault code(s).

TROUBLESHOOTING PROCEDURES

D4 Indicator Light And Transaxle Control Module (TCM) Locations


When the A/T control unit senses an abnormality in the input or output Systems, the S indicator light in the gauge assembly will blink at equal intervals and the LED display on the A/T control unit will blink a problem code when the ignition key is turned on. However, when the Service Check Connector (located to the lower right of the glove compartment) is shorted with a jumper wire, the S indicator light will also blink the problem code when the ignition switch is turned on.

When the S indicator light has been reported on, short the two terminals of the Service Check Connector together or pull the passenger's side carpet down from under the dashboard. Then turn on the ignition switch and observe either the S indicator light or the A/T control unit LED display.



Problem codes 1 through 9 are indicated by individual short blinks, Problem codes 10 through 15 are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the problem code. After determining the problem code, refer to the electrical system Diagnosis By Symptom / Symptom-to-Component Chart . See: Testing and Inspection



Some PGM-FI problems will also make the S indicator light come on. After repairing the PGM-FI system, disconnect the Back Up fuse (7.5 A) in the under-hood relay box for more than 10 seconds to reset the A/T control unit memory.

TROUBLESHOOTING MULTIPLE INDICATOR LIGHTS

The ABS/TCS and ATTS control units communicate with the ECM/PCM. If a DTC causes a loss of communication between two or more of these control units, the loss can cause multiple indicator lights to come on. For instance, when the ABS/TCS control unit stops getting data from the ECM/PCM, it sets a communication DTC such as TCS DTC 31 [engine retard command (PFINH) signal]. This DTC doesn't mean there's a circuit or control unit failure. It just means the flow of data between the ABS/TCS control unit and the ECM/PCM has stopped. If you troubleshoot the PGM-FI system or the ABS/TCS first, and clear the DTCs, you'll most likely fix the problem.

As a general rule, troubleshoot DTCs that aren't related to communication first.

For example, if DTC P1676 (FPTDR signal line failure) is set, and the ABS/TCS control unit has set a TCS DTC 24 thru 27 (TCS solenoid), troubleshoot the TCS DTC problem first.

A second example: If the ECM/PCM sets a DTC P1498 (EGR valve position sensor circuit voltage high), and the ABS/TCS control unit sets a TCS DTC 31, you need to troubleshoot the DTC P1498 problem first.

TO CLEAR FAULT CODES FROM THE ECU

1) Turn the ignition switch OFF.
2) Remove the Back Up fuse Fuse #24, 7.5A from the main (underhood) fuse box.
3) Wait 10 seconds for the ECU to clear it`s memory, and reinstall the Back Up (7.5A) fuse.

Amplifier Installation
written by: e3NiNe

[SPOILER="click here to view"]


Here's an image diagram of what everyone has said. (assuming you have an aftermarket radio, if you have a stock one, we'll have to slightly change this.)

1. connect the RCAs. You might have multiple RCA outs on your radio ... be sure to locate the "low pass" RCA.

2. Run the "remote" wire. The radio should have a blue wire (remote). Connect that to the sub.

3. Ground the amp. You need to attach a thick guaged ground wire from the amp, to a bare metal spot on your car.

4. Run the 12V power line. Be sure to include an inline fuse.



Random tips:
most stores carry an installation kit. These run about $30 and come with:
- long RCA cables
- 4g ground wire
- 4g 12V wire
- inline fuse

Run the ground wire away from the power wire.
Run the power wire away from the RCA's.
Wrap any bare wires in electrical tape.
Connect the battery last and be sure to have your fuse attached
