Just went to the Dodge dealer to get a new flasher for the directionals on my 2001 Dakota. Parts guy says they have one,....only,....$192!!!! WTF!

I passed. Back at home on Ebay I find the same part number for $129.86. Much better but c'mon, for a flasher?

Found another one on Ebay for the 2001 to 2003 Dakota, only $20, but not sure its a match.

There was a thread on another dak forum about an '03 rear brake lights inop (all other lights operative) & getting into the schematic on that, there is a lot of inputs and outputs from that flasher. I believe there were differences between the '01 & '03 exterior lighting circuitry, but, as OldMarine answered:

"[. . .]The combination flasher integrates brake light, turn signal, and hazard light inputs and sends to the appropriate lamps on the vehicle. This is not your grand-dads simple two- or three-pin flasher though. It's pretty sophisticated, [. . .] and has a 14-pin connector attached to it [. . .]"

The OP never did get back & follow up, however.

ON EDIT: Haynes is showing the same schematic for "01 & later" (meaning through '04) so it might be that they are the same flashers.

Thanks for the reply, I may just try the much less expensive 14-pin flasher relay.

 

[immattj]

I was thinking what you could do is go to Rock & pull up the combination flashers for an '01 and an '02 and '03 to verify that they are all actually the same.

Let us know how this turns out. I may have to do this some dy myself.

I did go to Rock Auto and found the less expensive flasher from the 04 Dakota. According to a vehicle match search on Rock it says it will not fit my 2001 Dakota.

On the O'Reilly's website I found an alternate that is less than $72:

This is the one that I would be inclined to want to use. Maybe you could het the seller to send you some pics of the pin layout and compare it to yours?

Thanks for the reply, I may just try the much less expensive 14-pin flasher relay.

There is no relay for that system on an '03; are you sure there is on your '01?

 

[andyvh1959]

I just referred to it as a relay, habit. After some other internet digging, it looks like the 2003 flasher does not fit in the 2001. I'll remove the one in my 01 Dak and compare it to the one at O'Reillys.

The reason its so expensive is its not just a flasher, its called a “lighting control module” or LCM. Its a rudamentry computerized module that functions like a flasher or a relay but is computer controlled by inputs from both the CTM and PCM.

The different versions for different years are NOT interchangeable.

 

[andyvh1959]

Thanks, that adds clarity as to why it is so expensive.

 

[immattj]

I was not aware that the CTM was another name for what is labeled as a "combination flasher" on the '01 & later schematic.

the part you replaced?

 

[CMax26mo]

Sorry, had the wrong name for it there (as is often the case in the automotive world, there are 3, 4 or 5 different names for every part). The 14 pin unit is not just a ‘normal’ flasher.

 

[immattj]

As is the case for most parts in the automotive world… there are 3, 4, 5 names for the same part.

. . . maybe, although I've never had to replace on my my '03 Dak, I've known there is a CTM & I know there is a combination flasher; I was just not aware that they were one & the same.

 

[CMax26mo]

The CTM controls things like the delay headlights, delay interior lights for example

I wish Novita made an LED friendly version of the LCM… that would have made my life a lot easier with my full LED lighting upgrade. I had to use 8 individual resistors to prevent hyper flash with my turn signals.

 

[immattj]

The CTM controls things like the delay headlights, delay interior lights for example

I understand that. The FSM lists the functions that the CTM controls. From other discussions on other Dak forums, I gather that the CTM does not control the same functions on all years; since I only have the '03 FSM I can only speak for the functions that it states that the CTM controls on that year. For example: on the '03, NOT the turn signals or the brake lights, but as I mentioned in one of the above posts, it does control the chime system.

But the schematic in the '00 - '04 Dak Haynes, does show for '01 through '04 a "combination flasher" (which does have inputs & outgoing for the brake lights & turn signals) which makes me think that, at least for an '03, that the "combination flasher" & CTM are not one & the same.

 

[immattj]

. . . I was also going to say that I was under the impressions that the functions controlled by the CTM was predicated by which bus system the Dak in question was utilizing. As an example, from '01 through '04 (& I believe SOME "00s) are on the PCI bus, and I was THINKING that this being so, on '01 through '04, the CTMs would control the same functions. I could be wrong about that, however.

 

[CMax26mo]

It seems to me that the engineers were experimenting with different ways to operate/control different functions in the 00-04 years as technology was evolving.

As I review the wiring schematics for these years, your right, each of them has different configurations.

 

[immattj]

It seems to me that the engineers were experimenting with different ways to operate/control different functions in the 00-04 years as technology was evolving.

Probably. On a another Dak forum a little while back I was helping a member troubleshoot inop brake lights (with the 3rd brake light & all other lights working) on an '03, and I used a Haynes for the schematics instead of my FSM & I accidentally started out looking at '00. When I figured out I was in the wrong year I went to "''01 and later" & the difference in those circuitries is significant.

Anyway, as an aside, it did turn out out that the OPs problem on his Dakota was that 14 pin combination flasher.
