Message:
hey guys, I'm trying to help out my friend who has a 2002 4.7 auto 2wd SCSB dakota. For some reason, his lights (all of them including the interior lights), power locks, intermittent wipers, and keyless entry thing arent working. it has happened to him before but the problem fixed itself, this time it isnt. the problem also seems to be brought on by rain. I can remember someone had this same problem one time and it was either a relay or a fusable link or something. I was hoping someone could help me out, i've been looking in my haynes manual but it doesnt really help. Thanks

I'm having an issue too. Coded a failed power steering pressure switch, no problem...ya right. Had no headlight, taillight,door locks, just like you. Seems that the failed switch was forcing fluid throughout my wiring harness. Computer filled, harness filled. I'm going to try a new puter this week, have been simple green, electric contact cleaning everything, so check your codes and pray!!

well, i dont know but you could have the same problem my friend did. It turned out to be the central timer module. It was under warranty so he just had the dealer fix it.

I had similar problems with my 03 QC. Door locks, intermittent wipers, headlight switch, 4x4 switch, interior and exterior lights...etc. all stopped working. It came and went, then came again, then went for a long time. Eventually it came back for an extended period and my shop diagnosed it as a Central Timer Module (CTM) problem and told me to take it to the dealer. I did some reading on this site and others and eventually found the TSB below. I followed the diagnosis instructions to reset the CTM (it may not have been fuse 13, but I found something similar in my 03), and I haven't had a problem since (more than a year). Cheaper than a new CTM...

Discussion:
This bulletin involves replacing the Central Timer Module (CTM) with a revised part.

Symptoms:
Strong electromagnetic fields or devices that transmit signals in the 315 Mhz range may cause the Central Timer Module (CTM) to intermittently lock up. CTM lock-up may cause a variety of customer complaints including:

Remote Keyless Entry Malfunction or Interior Lights Will Not Come On
Intermittent Wipers Will Not Function
Chime Malfunction
Power Door Lock Malfunction
Remote Radio Switch Malfunction (if equipped)
Heated Seat Malfunction (if equipped)
Engine Will Not Start (if equipped with Vehicle Theft Alarm)
No Communication With The DRBIII (No Response from CTM)
Essentially, all CTM controlled devices will not function if the CTM locks-up.

Customers that do experience this condition may:

have their vehicle equipped with after-market accessories that emit strong electromagnetic signals such as high output Citizen Band (CB) radios or Two-Way radios.
be equipped with transmitting devices that operate in the 315 Mhz range such as older analog garage door openers.
live or drive near devices that emit strong electromagnetic signals such as two-way radio communication towers utilized by the military, law enforcement, etc.
Diagnosis:
If the vehicle exhibits one or more of the conditions identified under Symptom/Condition, pull fuse 13 (power door lock fuse) for one (1) minute. Re-insert fuse 13. If the condition is no longer present, perform the Repair Procedure. If the condition still exists, further diagnosis is necessary, Refer to the appropriate Body Diagnostic Procedures Manuali or the service information available in MDS2 for additional information. If the customer indicates that they may have experienced one or more of the above conditions but were able to correct the condition by removing power to the CTM (pull fuse 13 - power door lock fuse or disconnecting the battery) and the condition cannot be duplicated, perform the Repair Procedure. Due to the nature of this issue, it may be difficult to re-create the customer's complaint

Parts Required:
AR (1) 56021861AK Module, Central Timer, Ram Van/Wagon
AR (1) 56045605AC Module, Central Timer, Dakota (Except Quad Cab)
AR (1) 56021223AN Module, Central Timer, Dakota Quad Cab And Durango
AR (1) 56045448AD Module, Central Timer, Ram Truck (Without Heated Seats)
AR (1) 56045999AD Module, Central Timer, Ram Truck Equipped With Heated Seats


Repair Procedure:

This Repair is compatible with DaimlerChrysler's Mobile service program and
does not require hoists or other full service facility special equipment.


1. Remove the CTM. Refer to the appropriate Service Manual, Group 8E, Central Timer Module, or the service information available in MDS2, for information regarding CTM removal procedures.

2. Install the new CTM (see Parts Required section). Refer to the appropriate Service Manual, Group 8E, Central Timer Module, or the service information available in MDS2, for information regarding CTM installation procedures.

Christina, what + probably meant was that you could start your own thread instead of posting on one that's two years old.

But to help with your problem, you may want to check for codes stored in the PCM. Most Auto parts can do that for free or you can try this.

Turn the key on/off/on/off/on the codes should display in the odometer as PXXXX and when it's finished or if there are no codes it will display Pdone. Most like;y sounds like there is a problem with your CTM(Central Timing Module).

Post back on a new thread.

problem is when I switch to high beam my dash starts to flicker like an emergency vehicle. When I exit the park lights will come on by themselves and stay on. Sometimes when I click to high beam the horn will sound. I replaced the turn signal switch and it was o.k for about a week then all started again

I am trying to help my sister find out what is wrong with her 2000 Dakota. Coming home from work today the dash lit up with a "check gauges" light. She noticed that the voltage gauge showed a spike in output. Now that she has turned it off, it will not start and the elec. windows do not work; although all lights and buzzers appear to.
I thought it might be a regulator problem, but having read this thread, I am wondering if it might be the CTM.
Not being familiar with these newer electronics, I am at a loss and she can't afford for me to start replacing unnecessary items.
Has anyone else had this problem? And if so, what do I need to look for? At least to get it started so she can take ot to a parts store and have it analyzed?
