Very hard to get to, underneath the dashboard in the middle. Make sure you eliminate everything else before you condem the DRL module, Good luck, Gary

2002 GMC Sonoma, is there a way to disconnect auto lights, just turning them off doesn't work. Truck will just shut off going down the road, have replaced steering column and brain, all lights everyth


Does yours have ZR2 option.?
The automatic lamp control (ALC) system and the daytime running lamps (DRL) feature, except the Canadian version, can be temporarily disabled by performing the following procedure:
  1. Turn the ignition to RUN.
  2. Press the DOME OVERRIDE button 4 times within 6 seconds.
A chime will sound informing you that the system is off. The system will remain disabled until the ignition is cycled off and then on or by pressing the DOME OVERRIDE button 4 more times within 6 seconds. The chime will sound again signaling that the system has been reactivated.
What brain did you replace ? You people crack me up , trying to save money by doing it yourself . You have no idea of the complexity of the system . You could have taken to a Qualified repair shop an spent less . Why on earth do you thing this has anything to do with the truck shutting off ? An it could have been as easy as hooking up the Tech 2 factory scan tool . There are a number of DTC'S - diagnostic trouble codes that could be set for the ALC .
DTC B2648
The body control module (BCM) monitors the courtesy lamp relay coil control circuit in order to determine if the daytime running lights (DRL) or the auto headlights (ALC) should be turned ON in the AUTO mode. When the BCM senses the ambient light sensor voltage is between 1.7 volts and 4.7 volts, the DRL will be commanded ON. When the BCM senses the ambient light sensor voltage is between 0.2 volts and 1.0 volts, the ALC will be commanded ON.
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the ambient light sensor parameter in the Body Control Module (BCM) data list .
Does the scan tool indicate that the ambient light sensor parameter is within the specified range?
0.2-4.7 V
DTC B2647
The body control module (BCM) monitors the ambient light sensor signal circuit in order to determine if the daytime running lights (DRL) or the auto headlights (ALC) should be turned ON in the AUTO mode. When the BCM senses the ambient light sensor voltage is between 1.7 volts and 4.7 volts, the DRL will be commanded ON. When the BCM senses the ambient light sensor voltage between 0.2 volts and 1.0 volts, the ALC will be commanded ON.
DTC B1398
And , if it was the BCM - body control module you replace , It's no wonder the truck shuts off , Don't know if your aware of it , but that brain needs to be programmed .
Important: If the module is replaced, the module must be programmed prior to performing the Passlock Learn procedure.
  1. Ensure that the following conditions exist in order to prepare for BCM programming:
  2. ?€¢
    The battery is fully charged.


    ?€¢
    The ignition switch is in the RUN position.


    ?€¢
    All accessories are turned OFF.


    ?€¢
    All modules and devices are connected and functioning properly before programming.

  3. Follow the SPS instructions on the Techline Terminal and scan tool to program the BCM.
  4. If the BCM fails to accept the program, perform the following steps:
?€¢
Inspect all BCM connections.


?€¢
Verify that the SPS Techline Terminal and scan tool have the latest software version.

This vehicle may have a daytime running lamp control module, probably needs replaced. May be able to pull fuse under hood in fusebox for a cheap fix. Its labeled DRL in lid of fuse panel.

try replacing your coil pack first. if that doesnt work then try replacing your ignition module. but no spark all the time leads me to believe its a coil pack gone bad.

Daytime running lights and blinkers do not work


the lights are controlled by a module, it is the DRL module, replace it. also try this
On the inside of the car next to the light switch there is your dome light button. GM made it to where you could turn off the daytime running lights by pushing it three times in and out. Turn the vehicle on then do this. Your daytime running lights should work after this.
