Not that I know of, new $$$ or another one from salvage yard but for (2500 - 3500) Ram truck.

Kelsey-Hayes All Wheel EBC 325 Antilock Brake System & Kelsey-Hayes Rear Wheel EBC 2 Antilock Brake System. CODE 84 - Mismatched VIN The only way you can get this code is if either the PCM has been offline for some time or someone replace original ABS module with salvage yard ABS module from wrong vehicle class (e.g. Durango or Dakota in Ram truck).

That sounds really easy then, except with the alarm if it's enabled the PCM or ECM need OK to Start message from CTM.

There is a couple programming options in CTM that can be either enable or disable, but the most important one is the alarm is it enable or not? I guess the easiest way to find out if the alarm is enabled, simply disconnect the white plug from CTM and try to start the engine. If the alarm is on the engine will cut out in about 5 Seconds. EDIT: The high-line and premium versions of the CTM utilize integrated circuitry and information carried on the Chrysler Collision Detection (CCD) data bus network along with many hard wired inputs to monitor many sensor and switch inputs throughout the vehicle. The features that the CTM supports or controls include the following: Automatic Door Lock - The high-line/premium CTM provides an optional automatic door lock feature (also known as rolling door locks). This is a programmable feature. Central Locking - The high-line/premium CTM provides an optional central locking/unlocking feature. Chimes - All versions of the CTM provide chime service through an integral chime tone generator. Courtesy Lamps - The high-line/premium CTM provides courtesy lamp control with timed load shedding. Door Lock Inhibit - The high-line/premium CTM provides a door lock inhibit feature. Enhanced Accident Response - The high-line/premium CTM provides an optional enhanced accident response feature. This is a programmable feature. Heated Seats - The premium CTM controls the optional heated seat system by controlling the operation of the heated seat relay. Illuminated Entry - The high-line/premium CTM provides a timed illuminated entry feature. Intermittent Wipe Control - All versions of the CTM provide control of the intermittent wipe delay, and wipe-after-wash features. Panic Mode - The high-line/premium CTM provides support for the optional RKE system panic mode features. Power Lock Control - The high-line/premium CTM provides the optional power lock system features, including support for the automatic door lock and door lock inhibit modes. Programmable Features - The high-line/premium CTM provides support for certain programmable features. Remote Keyless Entry - The high-line/premium CTM provides the optional Remote Keyless Entry (RKE) system features, including support for the RKE Lock (with optional horn chirp), Unlock, Panic, and illuminated entry modes, as well as the ability to be programmed to recognize up to four RKE transmitters. The RKE horn chirp is a programmable feature. Remote Radio Switch Interface - The high-line/premium CTM monitors and transmits the status of the optional remote radio switches. Speed Sensitive Intermittent Wipe Control - The high-line/premium CTM provides the speed sensitive intermittent wipe feature. Vehicle Theft Alarm - The high-line/premium CTM provides control of the optional Vehicle Theft Alarm features, including support for the central locking/unlocking mode.

I am assuming you don't have heated seats option -The Premium CTM controls the optional heated seat system by controlling the operation of the heated seat relay. I don't see any issues it's just 3,000 miles

I can get the central timer module and two new key fobs, then do the programming off the truck. eBay 56045202AA 1998 Dodge RAM 1500 Body Control Module Timing Alarm BCM CTM Amazon Car Key Fob Keyless Entry Remote fits Dodge 1999-2002 Ram / 1999-2000 Dakota / 1999-2000 Durango (GQ43VT9T, 56045497), Set of 2 Price: $32.99 Let me know if you are interested.

The DRB III emulator does work on later PCI (Dodge Ram 3rd gen) (not CCD 2nd gen) vehicles, read somewhere there may be a Smart Cable for older CCD. (The actual wiTECH is CAN only.) My beta test tool can program the key fobs but unfortunately it's not available on the market yet. https://mopar1973man.com/files/file/155-chrysler_ccd_beta_013inoinohex/

First of all happy Fourth of July everyone WHOA! what a mess. This is how I do it:

Huh... Good luck removing these rusty bolts, I replaced only one shackle the other day just to prevent this very issue, better get ready with bunch of sawzall blades and grinder blades

Good idea will try a new key soon, the 16bit key on counter got stuck on 65535.

This does not sound good, approximately 70% of fuel entering the pump is returned to the tank through the overflow valve and fuel return line.

PCI Bus = SKIM - (Sentry Key Immobilizer module) around the ignition switch assembly. Clarification: the key is a transciever and transmit key authentication to SKIM module, 2nd gen dodge ram doesn't have it

Instrument cluster not involved in security/anti-theft. The CTM provides the (PCM or ECM) with an "OK To Start" message via the CCD bus. Option is sitting in a CTM and it could be evoke only from there. There is not such option in PCM but the PCM or ECM will acquire this no start functionality option once and forever the second it sees VTSS message from CTM on communication network (CCD bus). VTSS system has nothing to do with SKIM or SKREEM and not VIN related.

This is partially correct, but once the alarm is enable the PCM will prevent engine running for more than 3 seconds, later on it will not start at all. Edit: I should also point out, I am not completely sure if it's the ECM or PCM involved in alarm no start functionality on cummins truck.

Interesting I can do this in my truck in any position even with the engine running thanks to my father, not sure how he managed to break it but hey I can go to the store leave the truck running locked with the keys in my pocket

Perhaps I can help but I'm not entirely sure if I can, this may sound funny but I am actually more familiar with CCD and SCI buses, Chrysler manufacturer-specific network protocol rather than the odb2 standard. I've been reverse engineering a lot the CCD (Chrysler Collision Detect) Data Bus protocol and Chrysler SCI Diagnostic Protocol for PCM and ECM. All ELM devices communicate with one of the five OBD-II Protocols standards: On-Board Diagnostics, or “OBD,” is a computer-based system built into all 1996 and later light-duty vehicles and trucks, as required by the Clean Air Act Amendments of 1990 There are five different communication protocols available under the OBD-II spec. 1- SAE J1850 PWM - Pulse Width Modulation, which runs at 41.6 kbps. This protocol was generally used on older Ford vehicles. 2- SAE J1850 VPW - This protocol is Variable Pulse Width, which runs at 10.4 kbps. GM vehicles typically used this version.(Many newer Chrysler Veh. including DODGE RAM 3rd GEN used (PCI Bus) J1850 VPW protocol) 3- The ISO 9141-2 (5 baud init, 10.4 kbaud) network is a single wire network - DODGE RAM 2nd GEN, 1996 Dodge Ram (Gas) and 2002 Dodge Ram Diesel both use ISO 9141-2 (5 baud init, 10.4k baud). Pin 7 on data link connector - ISO 9141-2 K Line, Logic level 0v to 12v - (high voltage is around 12+ volts or BAT voltage). If you have a older Chrysler, European, or Asian vehicle, this is your protocol. It runs at 10.4 kbps and is asynchronous serial communication. 4- ISO 14230 KWP2000 This is the Keyword Protocol 2000, another asynchronous serial communication method that also runs at up to 10.4 kbps. This also is used on European, or Asian vehicles. 5- ISO 15765 CAN This protocol has been mandated in all vehicles sold in the US from 2008 and later ( DODGE RAM 4th GEN ). However, if you have a European car from 2003 or later including 2004 Dodge Durango, 2005 Dodge Dakota, 2005 Dodge Magnum, 2005 Chrysler 300C, 2005 Jeep Grand Cherokee, the vehicle may have CAN. It’s a two-wire communication method and can run at up to 1Mbps.

Sounds like you are having issues with your Snap-on tool you either need update or some other interface for the tool you are using. I do have a Snap-on MT2500 the famous (red brick) with the 2004 MT2500VCI black cartridge no issues accessing ABS system. Since you are not complaining about missing speedo the ABS module has to be operational.

This could explain the P0121, Be sure to perform APPS Sensor calibration after the ECM swap.

You're right the switch is only preventing starter motor cranking.

Perhaps it's the switch. Make sure the CAV-PIN 6 works correctly (A/T) PARK/NEUTRAL POSITION SWITCH SENSE.

I believe the switch should be connected to (GND) in park or neutral position.

Key fob programming available in CTM menu, currently the beta software does not auto detect CTM version. You can only do this on High-line and Premium-line CTM version, if your truck has overhead console then it should be equipped with either High-line CTM or Premium-line CTM version. Three versions of the Central Timer Module (CTM) are available: Base version (CTM)~(No connection to CCD BUS) High-line version (CTM) and Premium-line version (CTM)~(heated seats option). https://mopar1973man.com/files/file/155-chrysler_ccd_beta_013inoinohex/
