    2004 Coupe Magnetic Red 6 speed

    Default I have a couple of issues I would like to fix... 2004 Coupe

    First I can't run my active handling and cruise at the same time. When starting on a trip and turn on the cruse it will go anywhere from 20- 50 miles and then start disengaging. I sometimes see the message on the dic that says Active handling, sometimes I just get the message cruise disengaged. After that it will do it a lot more often. i have switched to comp mode and it still does the same thing. After it kicks off I can reset it and it will go a few miles before doing the same thing. I check the codes and have none except for two HVAC codes B361H & B441H. Once I had a 363H but it hasn't reappeared. I was told I need a new swps but hate to replace it without knowing for sure its bad. The strange thing is the AC works great, cold on both sides.

    Any Ideas?

    Walter, Welcome to CAC. We have many really great people here that should be able to answer you questions. I'm not one of those...

    GMJunkie will hopefully check in here and give you a hand. But if I'm not mistaken when there is a problem with AH it will kick the cruise off and won't let it work. And I wonder if this is a similar problem...
    service traction control + abs

    As I said I hope that someone more knowledgeable then myself checks in soon.

    I assume you probly mean B0361H,B0441H and B0363H, Those are all left HVAC actuator codes,In my experience actuator Rt or Lt History are purdy common and the HAVC works just fine! I think sometimes that the actuator doors stick a little in extreme heat or cold and sets them!~!! Without any codes as far as the Cruse and AH I believe you have a High resistance ground somewhere,I'd clean and inspect all grounds first thing..........................

    Cruise Control Description and Operation

    Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at vehicle speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.
    The following are the main components of the cruise control system:
    • The powertrain control module (PCM)
    • The On/Off switch
    • The Resume/Accel switch
    • The Set/Coast switch
    • The TCC/brake switch
    • The stop lamp switch
    • The throttle actuator control (TAC) module
    • The Clutch Pedal Position (CPP) switch, if equipped with a manual transmission
    Cruise Control Engaged

    The TAC module monitors the signal circuits of the following cruise control switches:
    • On/Off
    • Resume/Accel
    • Set/Coast
    The PCM will engage and adjust vehicle speed based on the information received from the TAC module via the UART serial data link. For further information on the TAC system, refer to Throttle Actuator Control (TAC) System Description in Engine Controls--5.7 L.
    The cruise control switches are located on the multifunction/turn signal lever.
    Ignition positive voltage is supplied from the 10 ampere CR CONT fuse to the cruise control switch via the ignition 1 voltage circuit. When the normally open cruise control On/Off switch is turned On, the switch closes and the TAC module detects a high signal voltage on the cruise control on switch signal circuit. When the normally open Set/Coast switch is pressed, the switch closes and the TAC module detects a high signal voltage on the cruise control set/coast switch signal circuit. To engage the cruise control system, turn the On/Off switch On and momentarily press the Set/Coast switch. The TAC sends a UART message to the PCM, in order to confirm that the cruise control enable criteria has been met. The PCM will engage the cruise control system and record the selected vehicle speed. The PCM sends a class 2 message to the instrument panel cluster in order to illuminate the cruise control indicator. Pressing the accelerator pedal, while the cruise control system is engaged, will allow the driver to override the cruise control system in order to accelerate the vehicle beyond the current set vehicle speed. When the accelerator pedal is released, the vehicle will decelerate and resume the current set vehicle speed. The driver can also override the current set vehicle speed via the Set/Coast switch and the Resume/Accel switch. When the cruise control system is engaged, pressing and holding the Set/Coast switch will allow the vehicle to decelerate from the current set vehicle speed without deactivating the cruise control system. When the Set/Coast switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily pressing the Set/Coast switch will allow the vehicle to decelerate at 1 MPH increments for each time that the Set/Coast is momentarily pressed, with a minimum vehicle speed of 23 MPH. When the normally open Resume/Accel. switch is activated, the switch closes and the TAC module detects a high signal voltage on the cruise control resume/accel switch signal circuit. Activating and holding the Resume/Accel switch, when the cruise control system is engaged, will allow the vehicle to accelerate to a greater vehicle speed than the current set vehicle speed. When the Resume/Accel switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily activating the Resume/Accel switch will allow the vehicle to accelerate at 1 MPH increments for each time that the Resume/Accel switch is momentarily activated, with the maximum acceleration total of 10 MPH over the current set vehicle speed . Momentarily activating the Resume/Accel switch, after the cruise control system has been disengaged by pressing the brake pedal, will recall the previous set vehicle speed that is recorded in the PCM.

    Cruise Control Disengaged

    The PCM disengages the cruise control operation based on the information received from the TAC module. The TAC module monitors the signal circuits of the following switches:
    • The On/Off switch
    • The TCC/brake switch
    • The stop lamp switch
    • The CPP switch
    The TCC brake switch and the stop lamp switch are incorporated into an assembly and are mounted to the brake pedal bracket. Pressing the brake pedal while the cruise control is engaged will disengaged the cruise control system. The TAC module monitors the stop lamp switch signal circuit and the PCM monitors the TCC brake switch/cruise control release signal circuit. When the brake pedal is pressed, the normally closed TCC brake switch opens and the normally open stoplamp switch closes. The TAC module detects a high signal voltage on the stop lamp switch signal circuit and the PCM detects a low signal voltage on the TCC brake switch/cruise control release signal circuit. The TAC module sends a UART message to the PCM indicating the status of the stop lamp switch. The cruise control system will disengage when the cruise control On/Off switch is turned Off. The vehicle speed stored in the memory of the PCM will be erased when the Off button is activated, or the ignition switch is turned off.
    The clutch switch is mounted to the clutch pedal bracket. Depressing the clutch pedal while the cruise control is engaged will disengaged the cruise control system. When the clutch pedal is depressed, the normally closed clutch switch closes and the PCM detects a low signal voltage on the clutch switch signal circuit.
    The cruise control system will disengage when the PCM detects that the driver has the accelerator pedal override active for approximately 60 seconds.
    When the cruise control system is disengaged, the PCM sends a class 2 message to the IPC in order to deactivate the cruise control indicator.

    Cruise Control Inhibited

    The PCM inhibits the cruise control operation when any of the following conditions exist:
    • A cruise control system related DTC has been set.
    • The vehicle speed is less than 40 km/h (25 mph).
    • The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
    • The engine RPM low.
    • The engine RPM is high.
    • The vehicle speed is to high.
    • The system voltage is not between 6 volts and 16 volts.
    • The antilock brake system/traction control system is active for more than 2 seconds.
    junk!!

    Default Thanks for the ideas...

    I have been on vacation and away from internet service. I thought I had replied from my phone but don't see it here. I will start cleaning grounds as soon as I get a chance. I have already cleaned the two that are just behind the hood struts. I didn't really find much but did notice the studs were painted where the ground attaches. I am tempted to just cut those boxes off and crimp & solder all the grounds together on a ring terminal.

    Those box's are actually splice packs and will come apart to be cleaned!
