something's killing the batteries- when i went to test the current draw out of the DS batt, it popped the internal fuse on my fluke.

there's mention of a fan clutch connector to test/disconnect to see if the prob persists? where is this 6 pin connector>>>???? any other ideas about what's pulling it down? truck's stock, it sits for a month or so as i am out of the country a lot...

i want to try this 6-pin connector before i go and start disconnecting everything....where is it?

Greg

 

i found the connector. cleared the codes, and 3 came back, it was ****** i disconnected it.. cleared them again, and all codes are gone. i have unplugged it once more to let it sit overnight, and see if the batteries get pulled down with the clutch disconnected. we'll see what happens...

 

you are on the right path. Dealer connect says

Vehicle Issue MIL. P2509. The engine may stumble or stall out.;12 volt power (unswitched) and the ground circuits to the ECM are good. Batteries and charging system operation are good. If applicable (2006 and 2007 MY trucks), the ECM has already been updated per TSB 18-001-07.
System or Component Die out / Stall,Hesitation / Sag / Stumble;DTC / Error Message;ECM
Recommendation If the problem can be duplicated, disconnect the fan clutch 6-way connector and check if the concern still occurs. If the problem no longer occurs, replace the fan clutch assembly.

Here is the bulletin about it:



Flash: Check Gauges Lamp Illuminates For Alternator Charging With DTC P2502, P2503,
or P2509
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (Cummins PCM) with new software.
MODELS:
2006 - 2007 (DH/D1) Ram Truck (2500 / 3500)
NOTE: This bulletin applies to vehicles equipped with a 5.9L engine (sales code
ETH) built on or before November 29, 2006 (MDH 1129XX).
SYMPTOM/CONDITION:
The customer may experience the illumination of the “Check Gauges” lamp on the
instrument panel cluster. Inspection of the gauges may reveal that the battery charging
gauge may read in the 11 volt range rather than in the 14 volt range. There may not be a
Check Engine / Malfunction Indicator Lamp (MIL) illumination.
Further diagnosis may reveal the following Diagnostic Trouble Codes (DTC's) have been
set:
P2502 - Charging System Error - Diesel
P2503 - Charging System Output Low - Diesel
P2509 - Powerdown Data Lost Error - Diesel
DIAGNOSIS:
Using a Scan Tool (StarSCAN®) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTCs are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.
If the vehicle operator describes or experiences the Symptom/Condition, perform the
Repair Procedure.

1. Open the hood and install a battery charger. Using a voltmeter, verify that the charging
rate provides 13.2 - 13.5 volts. Set the battery charger to continuous charge. Do not
allow the charger to time out during the flash process. Remove the charger from the
battery when the flash process is complete.
NOTE: Do not allow the charging voltage to climb above 13.5 volts during the flash
process.
2. Obtain the vehicle Personal Identification Number (PIN). This information may be
obtained from:
a. The original selling invoice.
b. The DealerCONNECT system under the “Parts” tabs - select “Key Codes”.
c. By contacting the District Manager.
3. Connect the CH9410 StarSCAN® ethernet cable to the StarSCAN® and the dealer's
network drop.
4. Connect the CH9404 StarSCAN® vehicle cable to the StarSCAN® and the vehicle.
5. Power ON the StarSCAN®.
6. Select “ECU View”
7. Touch the screen to highlight the appropriate ECU in the list of modules.
8. Select “More Options”
9. Select “ECU Flash”
10. Record the part number at the top of the “Flash PCM” screen for later reference.
11. Select “Browse for New File”. Follow the on screen instructions.
12. Highlight the calibration then select “Download to Scantool”.
13. Select “Close” after the download is complete, then select “Back”.
14. Highlight the listed calibration.
15. Select “Update Controller”. Follow on screen instructions.
16. When the PCM update is complete, select “OK”.
17. Verify the part number at the top of the “Flash PCM” screen has updated to the new
part number.
18. The Wireless Control Module (WCM) requires updating of the Secret Key information
using the PIN information obtained earlier. From the StarScan® Home Menu:
a. Select “ECU View”.

awesome. the code has not reset, however the a/c decided to stop blowing cold air in the sonic drivethru. off to the dealer in the morning. what a POS. I just sold a '98 chevrolet 1500 with 278K on the clock, the only thing that died was the injection spider and leaky water pump. this POS has had new balljoints a new water pump, and whatever's broke now..... all before 40K. it's cummins dodge #4 between my father and I, and it will be the last.

 

UPDATE:

took it to the dealer- 2 bad batteries.... truck was charging at like 14.5-14.7 always, that may have contributed to their demise... reflash ( dealer wanted me to pay for a flash, i said no thanks on the paying part) reflash, 2 new 1k amp batteries... we'll see if that fixes it.. A/C compressor cratered, new one getting installed.
