Most all NAPA stores have an alternator bench tester. -
I jumped in as well. Finally got cheap $39 China Made stereo that has bluetooth. It can play video files from micro SD card. Bluetooth music from your phone as well as picking up phone calls. Back up camera is included. I'm holding out on the camera for right now it just too cold to lay on the floor routing wires over a frozen frame full of ice and slush. Very small unit in size. No CD ability. Even comes with two remote controls. I'm going to try the steering wheel remote and see how it does. https://www.amazon.com/gp/product/B07BLVWWG4/ref=ppx_yo_dt_b_asin_title_o01__o00_s00?ie=UTF8&psc=1 I tend to have all my MP3 file on my phone already and get all my new music from MP3Juices.cc .

Make sure you get ahold of @pepsi71ocean and give a review of this ECM/PCM provider. Need to keep a running tally of different shops and reviews. This helps other get good idea where to go.
-
Even stock setup with a fresh alternator would be in the 0.030 AC volt range or 30mv AC volts. To be 0.57mV AC I don't think is possible. This could be because its a low grade DVM and not capable of measure varying AC frequency.
-
This is why I suggested verifying with a bench test to make sure that its not just a "Cheap DVM" that can't measure odd frequencies.
-
Depends. Automatic transmission - The Steering wheel controls are received by the Central Timer then past on down the CCD Network to the PCM. Where the PCM talks to the ABS module to get road speed and then controls a vacuum motor pulling the throttle. This is because the throttle valve on the transmission needs to sense throttle position. Manual Transmission - The Steering wheel controls are received by the Central Timer then past on down the CCD Network to the PCM. Where the PCM talks to the ABS module to get road speed and then controls the ECM directly. (Fly by wire). As for wipers it could be the multi-function switch in the column is worn out.

@Auto Computer Specialist is in Florida. I had to make sure to make my phone call before 2pm MST. I would call first thing in the morning. I've always gotten the receptionist in the morning hours.
-
Yea... Its a corrupt ECM if the WTS is lagging now. this is a sign its having trouble booting up and getting to the first command to light the WTS light.
-
Remember there based in Florida so be aware of time zones.
-
Either P1698 or P1694 codes. One is PCM failure on the net. Then the other is ECM failure.
-
Go over the articles look up P1698 code and then look for the CCD network article. Then you'll want to test your alternator and do the W-T ground mod. As for CCD error double check the big connector in the PDC and the two connectors near the valve cover on the cowl.
-
Better off with an exhaust brake. This set of brake pads are going to clear 200k miles. Not worth it still doesn't change the wear aspect upgrading to 3rd Gen brakes.
-
I've heard of intake gaskets blowing out and having the same sound too.
-
No track bar. No sway bar. Possibly will change once its all assembled and tires mounted.
-
I kind of wonder if the battery could hold up long enough. Say a night time operation. No solar. Vehicle is disabled or away from a vehicle with battery source.
-
After all the pictures. I just sit back and wonder how much longer my factory OEM spare tire (Michelin) is going to last. It only been on the ground 3 times for less than 100 miles. Looks new. But the tire is over 17 years old now. Do I need a spare not really I so rarely use the one I've got.
-
B2 biodiesel still beats petroleum diesel. Any bio should be in the 200's HFRR score.
-
Yes sir it did. Now to get time to test it.
-
@dripleyYou're just going to have to pull that head off and get the head rebuilt while its off. Then new gasket kit for the upper end of the engine.
-
@IBMobile you need the 2 cycle oil for those augers so you can bore holes in the ice up at the lake so you can go fishing. Or your chainsaw to cut a hole in the ice. Still need 2 cycle oil.
-
I remember that back in the day. The member was making these with a lit up LED Cummins lettering. It was short lived and no longer produced as far as I know.

P0103 - Mass Air Flow Sensor "A" Circuit High Theory of Operation The Mass Air Flow (MAF) Sensor is a frequency based device. A constant voltage is applied to a heated wire. This wire is positioned in the air stream and is heated by the electrical current that the voltage produces. As air flows across it, it cools down. The heated wire or film is a Positive Temperature Coefficient (PTC) resistor, which means that the resistance of it drops when the temperature drops. The drop in resistance allows more current to flow through it in order to maintain the programmed temperature. The current flow is changed to a frequency, which is sent to the Powertrain Control Module (PCM) and interpreted as air flow. Adjustments for air temperature and humidity are taken into consideration, since they also affect the temperature of the heated wire or film. The engine running monitor compares an estimated fresh air flow value to the MAF Sensor reading. When Monitored and Set Conditions When Monitored: This diagnostic runs continuously when the following conditions are met: • With the ignition on. Set Conditions: • The Powertrain Control Module (PCM) has detected the Mass Air Flow (MAF) Sensor value is above a calibrated threshold. Default Actions: • The MIL is illuminated.
