Tried to do the battery cable reset and dont think it worked.

2003 Accord

1. disconnected battery
2. used jumper wires connected to both battery cables
3. let sit for 15 minutes
4. reconnected battery
5. expected to have to enter the radio code, radio and presets were all still there, just had to fix the clock.

The second time i tried it i turned the key on while I waited the 15 minutes, still the same results. Did I miss something?

Perhaps the 03 is different than my 04, but if the car is truly disconnected from the battery, the radio won't work until the security code is entered. So, this might sound like a stupid question, but how are you disconnecting the battery? Another possibly stupid sounding question, what's the point of the jumper cables?

Well I remember before unhooking the battery and having to reset the radio but for some reason It doesnt do that anymore?? lol. Im disconnecting the battery by removing the neg cable from the battery and then the pos cable from the battery. Not jumper cables but a jumper wire to hook the battery cables together to reset the computer.

I don't understand this part.

When you disconnect the + and the -, that's it. Wait. And reconnect the + and -.

What is "hook the battery cables together?"

Honda has two different methods for the battery cable reset. It is done principally to reset the multiplex integrated control system. Not so much of resetting trouble codes, as the PCM has non-volatile memory.

1. One method is to disconnect the negative cable (disconnect negative first) and then positive cable. Then connect them together with a jumper wire for 15 minutes.-- Do not touch the battery terminals. You'll need the radio's anti-theft code afterward.

The 15 minute reset doesn't require turning the ignition ON, etc.

2. Honda has a variation of the battery cable reset which requires turning the ignition on and off; but, only requires 10 minutes. This video is the 10 minute method.

Tried both methods and assume it did not work cause I did not need to enter the radio code when I turned the car back on.

That is the pic. I posted in another thread.

Just because the radio code is not needed does not necessarily mean the multiplex control system was not reset.

Why are you doing the battery cable reset? What issues are you having?

poprocksncoke

yes, that is where I got the instructions but not sure why it is not working.

Passenger side door lock wont lock/unlock with the controls like all the other doors, was hoping this would fix it cause I didnt feel like taking the door apart.

How would I know if it was reset then? only thing that changed was the clock.

1. Is this a sedan or coupe? Sounds like a sedan, since you mentioned other doors.

If it is a sedan and only one passenger power door lock is not working, it is unlikely an issue with the multiplex control system. So, a battery cable reset in this situation is practically pointless.

2. Probably is door lock actuator or wiring issue. Is it the front passenger door not working?

poprocksncoke

yes, the front passenger door.

Sedan or coupe?

Sedan

1. Probably a bad front passenger door lock actuator.

2. Although it would be more direct to take the door panel off and test the motor; here is another way to test the front passenger motor without taking off the door panel. If a wire has an open (break), then this test wouldn't be 100%.

a. Remove or lower the glove box like if you're changing the cabin filter. You can search for videos on that; so, I won't post how to do that. - EASY

b. There is a 12P gray connector behind the glove box. Unplug this connector and leave disconnected during test.

To test if motor unlocks: Use a jumper wire between female terminal no. 1 (Yel/Blk wire) and female terminal no. 12 (blk wire - ground). Use a second jumper wire between female terminal no. 2 (Yel wire) and female terminal no. 3 (Wht/Blu wire - Fused power). Only do this briefly to not burn out the motor if it is good. - EASY

To test if motor locks: Use a jumper wire between female terminal no. 1 (Yel/Blk wire) and female terminal no. 3 (Wht/Blu wire - Fused power). Use a second jumper wire between female terminal no. 2 (Yel wire) and female terminal no. 12 (Blk wire - ground). Only do this briefly to not burn out the motor if it is good. - EASY

thanks, i will try and test it out this weekend.
