How to retrieve Acura and Honda Radio Code

From an Anti-Theft ID Card

The code and serial number for the radio and navigation is written on an anti-theft ID card. The dealer recommends you to keep the card somewhere safe outside the vehicle. So, if you never pay attention to this card, it is most likely in a folder of an owner’s manual and warranty booklet, etc.

A sticker on a glove box

If you can’t find the card, look at the side of the glove compartment. You can find a sticker with the code and serial number on the inner wall of the glove compartment. Unlike a card, it may just show the code and serial number without telling what they are for. But, now you know. The code is likely only numbers of 4 or 5-digit, and the serial number is likely around 10-digit alpha-numeric.

Through a website

In case you don’t find either a card or a sticker, you still can retrieve that through a website. You will need to enter the following information to retrieve the code through a website.

Name, Address, Email address, Phone number, VIN, and Serial number.

Where can I find VIN?

VIN stands for Vehicle Identification Number. It is 17-digit alpha-numeric. It’s like a serial number of a vehicle. Any car has it. You can find that on several places.

On the vehicle’s registration
On your insurance card or statement
At the corner of dashboard on the driver’s side (looking through the windshield from outside)
On a sticker inside the area where the driver’s side door latches to the car

After you have a major repairs that require to disconnect the battery, you may notice your Acura or Honda power window problems. Although you can open and close the windows by pressing or pulling the buttons, AUTO UP and AUTO DOWN features don’t work.

AUTO DOWN is the feature that pressing the button firmly down opens the windows all the way. And AUTO UP is the feature that pulling the button firmly back closes the window all the way so you don’t have to keep pressing or pulling the button.

If you experience this problem, all you need is reset the power window control unit. Here is the procedure.

1) Turn the ignition switch ON (II).
2) Move the driver’s (or the front passenger’s) window all the way down by using the driver’s window DOWN switch.
3) Open the driver’s door.
Note: Steps 4 to 7 must be done within 5 seconds of each other.
4) Turn the ignition switch OFF.
5) Push and hold the driver’s (or the front passenger’s) window DOWN switch.
6) Turn the ignition switch ON (II).
7) Release the driver’s (or the front passenger’s) window DOWN switch.
8) Repeat steps 4 to 7 three more times.
9) Wait 1 second.
10) Confirm AUTO UP and AUTO DOWN do not work. If AUTO UP and DOWN work, go back to step 1.
11) Move the driver’s (or the front passenger’s) window all the way down by using the drivers (or the front passenger’s) window DOWN switch.
12) Pull up and hold the driver’s (or the front passenger’s) window UP switch until the window reaches the fully closed position, then continue to hold the switch for 1 second.

If you go to the dealer to fix this problem, you may be charged for half an hour labor cost. This procedure is written on the owner’s manual. This is a good example that the owner’s manual is somehow neglected but actually it’s a great source of information about your very own vehicle.

And, it’s the common procedure among Acura and Honda vehicles with AUTO UP/DOWN features.

Acura and Honda Idle Relearn Procedure

Leave a reply

Late models of Acura and Honda vehicles equip an electronic throttle body (ETB). The ETB is fully controlled by a vehicle computer. The vehicle with the ETB has no longer mechanical cable between the throttle body and accelerator pedal. Instead, the computer sends a signal to the ETB to open and close the throttle plate based on the parameters of various sensors throughout the vehicle. After you replace or clean the ETB, reset the vehicle computer, you will need to have the computer relearn the right throttle position and parameters of other sensors. Here is the Acura and Honda idle relearn procedure.

1) Make sure all electrical items (A/C, audio, lights, etc) are off.
2) Reset the ECM/PCM with the HDS.
3) Turn the ignition switch to ON (II), and wait 2 seconds.
4) Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194°F (90°C).
5) Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes.

HDS stands for Honda Diagnostic System. In the step 2 of this procedure, it’s referring to Honda’s OBD software and/or hardware. If you don’t have one, you may be able to reset ECM/PCM with an aftermarket OBD scan tool. If not, disconnect a battery for about 15 minutes.

The last step of the procedure, you shouldn’t include time while a radiator fan is spinning into the 5-minute idling time. So, be aware that it takes longer than 5 minutes in most cases.
