i have a 2007 ram 2500 with 5.9 diesel. ive had the truck for 2 years and the other day my wait to start light and buzzer started going off while i was driving down the road and now it has happened four times now. all while driving down the road. the light does not come on when i first turn the key on. all gauges look fine and truck runs great, any suggestions?

 

Check all connections on batterys make sure they are clean and tight. Check connection on the heater solenoid just below the right side battery. Make sure they are tight no loose connections. Have the batterys tested if over 5 years old, or just replace them if they are that old, they are due to fail.

 

thanks i will try that

 

i thought that would work but just before i got home it did it again

 

You may want to check for any codes, PCM flash update maybe all that is needed, depending on what codes are setting.

 

When was the last time your ECM was updated? Are you running a recently updated tuner?

The WTS is a recent issue with some Chrysler software, it indicates too much calculated injector return flow. It's supposed to not be accurate most of the time.

 

Check all connections on batterys make sure they are clean and tight.

 

dodge dealer put in new updates to help my fuel mileage about 6 months ago.which by the way i put new exhaust from turbo back and i didnt see a mileage increase so im hesitant on purchasing a tuner. any suggestions on that?

the guy who checked my batteries didnt disconnect them before testing. i had them retested and had a bad battery, so i put in two new ones and the light and buzzer has not come on so i think it is fixed. thanks so much bigiron70 and the rest of u who replied. my best friend who was a diesel mechanic just passed away recently. so u dont know how much yall help people thanks again.
