Bypass the drl module?
 

Well I have a 2004 chevy optra and I want to bypass the drl. I have been searching all over the net with no luck. Can anyone point me in the right direction.

Its draining my battery overnight. I need to get it fixed asap. Thanks.:D

I'm 99% sure its integrated into BCM, so its not something you can just bypass. You'll have to take it to the dealership and probably get the BCM replaced.

No its a recall, its not integrated in the BCM, and you can bypass it. Here is the info below(I need to know how to do the bypass):

Transport Canada Recall # 2007315 Recall Date: 2007/09/28 Notification Type: Safety Mfr System: Lights And Instruments Manufacturer Recall Number: 07240 Units Affected: 33,865 Category: Car Recall Details: Certain vehicles may experience a loss of headlamp low beam or Daytime Running Light (DRL) function as a result of a melted instrument panel harness connector. Low beam failure would lead to reduced visibility during hours of darkness. DRL failure may render the vehicle less visible to other motorists and pedestrians during daylight hours. Both cases could lead to a vehicle crash with injury or death. Correction: Dealers will add a direct connection splice clip to the headlamp low beam circuit in order to bypass the faulty connector. Make Model Model Year(s) Affected CHEVROLET OPTRA 2004 2005 2006

I was thinking you were asking about disabling the DRLs altogether... Not simply bypassing the connector. In this case, more information would have been helpful.

I said bypass in my first post.

All the TSB is talking about is bypassing a faulty connector, not the whole "module" for lack of a better term..

<HR>Step 10 of the service procedure in this bulletin has been revised. Please discard all copies of bulletin 07240A, issued November 2007.
<HR>Condition

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2004-2006 Chevrolet Optra model vehicles sold in Canada. Some of these vehicles may experience a loss of headlamp low beam or DRL (Daytime Running Light) function as a result of a melted instrument panel harness connector. Low beam failure would lead to reduced visibility during hours of darkness. DRL failure may render the vehicle less visible to other motorists and pedestrians during daylight hours. Both cases could lead to a vehicle crash.
This condition may be caused by a poor electrical contact of the terminals in the wiring harness splice pack (SP201), resulting in an electrical-arc and melting of the splice pack housing. The melted plastic material may remain inside the terminal contact area breaking the low beam headlamps and DRL circuits. The SP201 splice pack connects common wires for the headlamp and DRL systems.
Correction

Dealers are to inspect the SP201 splice pack for thermal damage and/or poor connections and repair by removing the three affected wires from the splice pack and crimping them together with a separate splice.
Vehicles Involved

Involved are certain 2004-2006 Chevrolet Optra vehicles built within these VIN breakpoints:

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS. Not all vehicles within the above breakpoints may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the GMinfoNet Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several provinces. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.
Parts Information

Parts required to complete this recall are to be obtained from General Motors Service and Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

Service Procedure

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in SI.

   http://gsi.xw.gm.com/si/images/tif.gif
3. Detach the SP201 splice pack from the tie bar located on the left hand side of the steering wheel. The splice pack anchor is located under the dash panel to the left of the steering column. Release the anchor of the splice pack by squeezing the anchor catches and pushing the anchor through the hole.

4. Pull the splice pack out from in between the A/C duct and dash support structure. Inspect the splice pack for the three purple wires shown above. Cut the three purple wires indicated by callouts 1 through 3 well away from any melted or damaged areas close to the splice pack. The two inboard wires may be found in the cavities indicated by either callout 2 or 3. (Wires in illustration above are shown at position of callout 2.)

5. Strip approximately 20 mm (0.75 in) of insulation from the ends of the three purple wires and splice using blue splice (P/N 19168447). Insert the wire from callout 1 into one end of the splice and the remaining purple wires from callout 2 or 3 in the other end. Crimp the connector using a standard crimping tool and seal the splice sleeve using Ultra Torch or another approved heating tool. Refer to Splicing Copper Wire Using Splice Sleeves in SI.
6. Temporarily connect the three IP connectors to the instrument cluster. Connect the negative battery terminal and test the headlights. The key must be on for the headlights to operate. If the headlights do not operate, further diagnosis is required. If the headlights operate properly, turn off the ignition, disconnect the battery, and continue with step 7.
7. Reattach the splice pack to its original position on the tie bar to prevent dash rattles.
8. Install the instrument panel cluster and trim. Refer to Instrument Panel Cluster (IPC) Replacement in SI.
9. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in SI.
10. Verify that the headlamps, Daytime Running Lamps, and the DRL indicator light in the instrument panel are fully operational.

Bypass the drl module
 

I have a couple of Datong FL-3 audio filters. The FL-3 is an FL-2 with the addition of an auto-notch board.
Since the device itself limits audio recovery to between 250 and 3500 Hz, I would like to bypass the other functions and use only the auto-notch function. Do anyone have an idea of how to do this?
