2010 Dodge Ram 1500 5.7 quad cab. The issue started with what I thought was a weak battery. Replaced the battery and had no issue for a couple of months. Then I let the truck sit for 4 days and the truck will not start. Two weeks later the battery drains overnight. Battery drains down to approximately 4 volts.
The intermittent draw on the battery with everything started off around 3.2 amps. When the truck is not drawing 3.2 amps, loads hover around .1 to .250 amps. I have been dealing with this issue for about 5 months with 4 months at the dealership. The dealership gave up and stopped trying to fix the truck. Truck has a lifetime bumper to bumper warranty from FCA, FIAT CHRYSLER AUTOMOBILES. I had to buy some parts out of pocket and try to get reimburse by FCA. The dealer would not buy used parts because some of parts are no longer sold by dodge. FCA says the dealer has the form for me to be reimburse, the dealer says they don't have them. I am tired of dealing with both the dealer and warranty people. I am out of ideas and need help. I have read every thread online about this and still can't figure my problem out. Everything is factory on the truck no aftermarket mods, except for the radio which was installed last week. So while its a lifetime warranty it still costing me to fix the issue.
Here is what I know so far, measured with a fluke 376FC clamp meter .x amp or a fluke 117 for .*** amps
Battery 6 months old 800cca tested by 4 independent shops, test ok.
Soft/hard reset with battery cables tied together, no help.
PCM/ECM unplugged 4 plugs no help.
Removed hood light, no help
Disconnected Amp, no help
Disconnected subwoofer, no help
Glove compartment light verified to work properly.
Removed M39 fuse IOD radio, the intermittent draw drops down from 3.2 to .8 amps. Factory radio replaced with another factory radio no change. Replaced factory radio with aftermarket radio, intermittent amp draw now around .8 amps. I believe something is waking up the radio and the aftermarket radio does not respond. You can hear the factory radio (both used and old) cycling when the amp draw spikes.
Removed M38 fuse IOD CCN/interior mods, load drops from .8 to .044 amps measured from battery terminal. Battery remains charged if removed. Amperage load measured across the fuse is about .2 amps.
Removed M34 fuse BAT CCN/interior light/SCM sw bank, load drops from .8 to .044 amps measured from battery terminal. Battery remains charged if fuse removed. Amperage load measured across the fuse is about .7ish amps. Yes the interior lights are off. This circuit I believe has the remaining load on it.
Cluster removed and not reinstalled, no amp draw battery stays charged.
Cluster replaced with used one, no help still drains the battery.
Clockspring replaced, no help.
Removed power lead to TIPM module battery stays charged.
Parts replaced so far.
Factory radio(used) no change, see above.
Clockspring (new) replaced, no help.
Instrument cluster (used), replaced no help.
Anyone have an idea what is on the M38 and M34 circuit? I believe the CCN is built into the instrument cluster and the clockspring is the SCM. What else could be waking up the truck....TIPM? Door module, pulled the J07 and J03 (door nodes) fuses ampraged still spiked.
I have not tested the TIPM module and don't want to spend another 600-1000 buck on a guess. Dealer says the TIPM was replaced in 2017 but I don't believe them as the case has a 2010 date on it. Anyone have any information on how I can test mine. Everyone I called only wants to sell me a rebult or new unit even if they list repair services. I can hit the tipm with a rubber mallet (firm but not hard!) and the amperage will spike to .8 amps maybe five out of ten times. I was able to do same with the PCM/ECU, but when I unplugged it it still spiked lol. Yes I know thats not a scientific approach to troubleshoot
!
So far my fix has been to use the fuel pump relay wire bypass kit. I took power from M49 IGN R/ACC/Bat-Pwr Outlet #3, fuse to power the M34 fuse. M49 only gets power when the key is turned on. When either the M38 or M34 fuses are pulled the battery stays charged. The only thing that I see that does not work normally is the interior dome lights with my mod. They dont come on till the key is turn on. Remote start unlock/lock still works. Any place where I can get tap power from when I hit the door locks? I don't mind installing a relay just need a proper trigger circuit and of course I am working without a wiring schematic.
Anyone have any other ideas, I'm out of them.
Below are the three loads graphed out from my meter. My bypass fix is the last image.
Thanks for reading.
