#272 of 391 Re: Interior lights stay on when engine is running [tladell] by dustyk Dec 22, 2008 (11:50 am)
Replying to: tladell (Dec 22, 2008 7:27 am) According to the 2003 Dakota wiring diagram, the fuse for power to the Overhead Console is fuse #1 (cavity 1) in the Junction Block.   There are two areas that contain fuses, circuit breakers, and relays in Dodge trucks. One is called the Power Distribution Center (PDC) and is located under the hood, usually next to or very near the battery.   The second area is called the Junction Block (JB) and on Dakotas is located at the end of the instrument panel on the driver's side. This area uses a trim panel to cover the JB and is easily removed.   The fuse you are looking for is in the JB.   Does your model have a Dome Lamp as well?   Regards, Dusty Replies to this message: tladell (Dec 22, 2008 12:31 pm) dustyk (Dec 22, 2008 1:15 pm) tladell (Dec 22, 2008 2:07 pm)

Replying to: dustyk (Dec 22, 2008 11:50 am) I do not have a dome lamp, just 2 lights in the overhead console. The owners manual for my 1999 Dakota Sport (no extended cab) says the #1 cavity in the JB contains a 20 Amp fuse for the stop lamp & the #11 cavity contains a 10 Amp fuse for the Console/Purge. Is this the right cavity for the overhead console lights (2) & underpanel courtesy lights (2)? Maybe it is different than the 2003 Dakota.   Sorry for all the questions Dusty. Again, I appreciate your help. Replies to this message: dustyk (Dec 22, 2008 1:15 pm) tladell (Dec 22, 2008 2:07 pm)

Replying to: tladell (Dec 22, 2008 12:31 pm) Ah. First problem is I do not have a '99 Dakota service manual at my disposal. Unfortunately, mother Mopar has a habit of changing electrical wiring, sometimes even during mid year.   However, I have to agree with your original assumption that if the courtesy lamps are still illuminating, they must be getting a DC supply from somewhere. So I think the fuse they're identifying in the book is incorrect.   I may not have the correct documentation for your year Dakota, but I'm somewhat confident that the problem is going to be the CTM, especially since in previous years this was fairly common problem component.   The CTM contains semiconductive drivers that control numerous electrical devices in the vehicle. These are placed on the low side (negative) of a device and permit the device to operate underr certain condditions. For example, the overhead courtesy lamps illuminate when a door is opened or unlocked and stay illuminated for several minutes or until the ignition switch is turned to the run position. It is the driver in the CTM that provides the conductive path for this feature. In this case, I think the driver has shorted allowing the lamps to be on all the time.   I've been told that there are a couple of diodes in the CTM that commonly fail and the CTM can be opened and repaired. I've never done this myself. If you are an electrical type of person you might be able to verify the problem and repair the CTM.   Best regards, Dusty Replies to this message: tladell (Dec 22, 2008 2:07 pm)

#276 of 391 Re: 88 dakota intermitant no start [dusty9] by dusty9 Jan 02, 2009 (5:57 pm)
Replying to: dusty9 (Sep 16, 2008 4:19 am) After 4 tows to the shop the truck stayed dead long enough for them to find the problem. It turned out to be a "crank angle sensor"-it is attached to the distributor somehow. This thing has been going bad for months but would only stay bad for a few hours, days or minutes so by the time I got it into the shop it would start right up. Finally it died for good. -a $50 part that cost me almost a grand in detective work and towing. Replies to this message: dustyk (Jan 03, 2009 11:01 am)

Replying to: dusty9 (Jan 02, 2009 5:57 pm) Glad to hear the problem has been solved. The term "crank angle sensor" is foreign to Mopar parlance, I suspect the defective part was the Crankshaft Position Sensor or a Hall Effect Distributor Sensor. Crankshaft Position Sensors were a somewhat common failure item on Dakotas of your vintage.   Best regards, Dusty
#278 of 391 96 Dakota, No headlights, tailights, locks... by mski1 Jan 04, 2009 (12:09 am)
Having a weird issue with my Dakota. 1996 SLT 4x4 V6.   Headlights/tailights do not work Power locks either don't work or when you push one it clicks really fast multiple times.   Also, turning the headlights on, pressing the brake pedal or using the locks will cause the ABS and Brake light (on instrument cluster) to come on.   Checked as many grounds as I could find and nothing seems to work as of yet,   Any suggestions?   Thanks in advance   Mike Replies to this message: dustyk (Jan 04, 2009 9:03 am)

Replying to: mski1 (Jan 04, 2009 12:09 am) In the absence of any diagnostic data, either preliminary visual (fuses, etc.) or actual voltages checks, I'd be suspicious of a defective Central Timer Module (CTM). However, I would suggest getting a wiring diagram and performing some voltage checks. I'm not sure what bearing a bad CTM would have on the ABS lamp illuminating at the moment, but a common component to the power locks, taillights, and headlights is the CTM.   Best regards, Dusty
#280 of 391 It had to be an electrical problem..... by GranpaBob Jan 04, 2009 (4:50 pm)
99 Dokata 5.2L - Won't start. It was getting gas, spark, air... everything was testing OK. I replaced the Crankshaft sensor but it didn't help. Checked the Camshaft sensor. It was reading good at 5V. The next step was to replace the PCM (ugh! $200 bucks minimum!). I cranked it over one last time to see if it kicked out any codes. My son noticed a blue spark close to the passenger side firewall. Sure enough! The heater hose covering had rubbed the spark plug wire and somehow, it was grounding out. We separated the hose from the wire, and it fired right up! We then replaced all of the spark plug wires and the distributor cap and button. So - Lessons learned - check all the basics before replacing components. (Although, we did check for spark on some of the plugs and eliminated that as a possible problem.)   Bob
#281 of 391 Dome light stays on in 99 dakota slt 4x4 by mchase Jan 06, 2009 (2:50 pm)
Similar to a post last month, my dome/cab light stays on after I start the engine in my 99 Dakota. So I am currently driving around with the dome light on. It does eventually turn off after the engine is shut off, the key is removed, and the door is closed. I think the final thought, on the previous post, was that the CTM had gone bad. I have a couple of other questions.   0) Does that sound logical here?   1) Where is the CTM located and what does it look like?   2) Can I replace it myself?   3) Does the module need to be programed by the dealer?   4) About how much should a programed CTM cost?   5) Is the only place to buy it at the dealer?   Thanks Mike Replies to this message: dustyk (Jan 10, 2009 10:21 am) mchase (Jan 12, 2009 5:41 pm)
