1999 Dodge Caravan Instrument Cluster, ABS Lights.

abestpcs

I have a 1999 Dodge Caravan LE 3.3 L 2 Front Wheel Drive, 4 Speed Auto Transmission.

Problems/Symptoms:
1. ABS Light But ABS Still works
2. Air Bag Light
3. No Horn
4. No interment cluster information only backlights
5. OBD Error Initially Showed ECM I/O Read Error
6. OBD After ECM Check P1698 PCM not Communicating with TCM

Possible Causes:
My brother drove through a flooded parking lot that was bumper high or higher.

Troubleshooting Steps:

1. Replace The Interment Cluster Board with 2 other used ones. This helped for very short while.

2. Got Error Code for ECM I/O Read Error But it ran fine other than above issues.

3. Sent the ECM to a circuit Repair Shop checked out with issues beyond repair or other issues causing error.

4. The EXM code went away and now a PCM cannot communicate with TCM P1698.

5. Had the transmission fully diagnosed and not the issue.
The Transmission shifts fine and goes into reverse without any issue or unusual noise.

6. Needs to be inspected by this Friday!
What could be the cause by this and how to fix it.

"Replace The Interment Cluster Board with 2 other used ones. This helped for very short while."

The fact that it only helped for a short while seems to indicate that you may have some water damaged wires, creating a short somewhere which is frying the cluster board circuits.

You are describing symptoms that would normally be associated with a loss of communication between the different modules on the car. Your going to need the help of a technician who is skilled in diagnosing communication databus faults.
