The p1698 code is for the (bus) that is how the computers commmunicate with each other and also how the scan tool talks to the computers.

There is a common problem with these vans, that would be a good place to start. The battery will leak acid onto the wires underneath the battery. If you remove the battery and battery tray you will be able to see the large wiring harness under the battery. Inspect all of the wires underneath the battery for damage.

It means that it didn't receive a signal from the transmision module.
Have your transmission control module checked.

To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.

SOURCE: 1996 trouble codes are P1698 plus P0171 PLUS

P1698 = DRB display of: No CCD Messages from the TCM (Transmission Control Module) = No messages received from the TCM.
Basically the Transmission is not sending information or enough information to your Power Control Module. P0171 = DRB display of: Right Rear/or just Fuel System Lean (not enough) = A lean air/fuel mixture has been indicated by an abnormally rich connection factor. Either too much Air or not enough Fuel.
On the Transmission issue:
1. Check the Transmission Control Relay in the IPM (fuse box under the hood). On the cover should be the identification of where each relay is. This Relay may be bad. Does your Horn work? The Horn Relay and Transmision Control Relays should be the same. Change the Horn Relay and the Transmission Control Relay. Try your Horn now. Not working? The Relay is bad. If this is not the problem GO TO #2.
2. Check your Transmision Fluid ...Level?
3. When was the last time the fluid and filter were changed?.
4. Check the connection of the wiring harness to the Transmission Solenoid. Loosen the bolt (believe it is 8mm) holding down the wiring harness to the solenoid and pull up/off the connection. Check the wiring for connections, corrosion, pitting or burn marks.
On the Fuel Issue: there are many possibilities. Some are:
1. What gas was put in last? Using old gas (from a gas can) can cause this.
2. When was the last fuel filter changed?
3. When were the Fuel Injectors tested?

The description for fault code P1698 is "No CCD Messages Received From PCM" The CCD bus is the circuit that your computer system uses to communicate between the computers. There are several Computers in your vehicle. You didn't mention year or model or engine size, so I can't be specific, but most have at least an Powertrain Control Module (PCM) computer, Transmission Control Module (TCM) computer, an Antilock Brake System (ABS) computer, a Passive Restraint (Air Bag) computer and the Instrument Panel Cluster (IPC) when one of these computers are unable to communicate through the CCD Bus, the other computers will tell on it. Thus, code P1698.

This can be an internal fault in the PCM (not very likely) it can be a shorted or open CCD Bus circuit, or it could be caused by the PCM losing one of its power or ground circuits and momentarilly shutting down. If your instrument cluster is also having problems like you described, the problem is most likely a power or ground circuit malfunction. The rest of your computers need to be scanned to assist in pinpointing the actual cause of this code. The "Generic OBD" scanners that they use to sell parts with at the auto parts stores do not have the capability to scan your ABS, IPC, Air Bag, or other modules. They can also not access the "Vehicle Specific" side of your PCM. They can only scan the "Generic" codes that are output by the PCM. Again, this is most likely caused by an open or shorted circuit or even a malfunctioning ignition switch - something is most likely causing the PCM, the TCM or the IPC to lose power while you are driving.

Check engine light is on with code p1698 what is this code


The code P1698 is: No CCD messages from TCM. That means the communication between the Transmission Control Module and the Power Control Module is lost. Sometimes this happens when a PCM, or TCM is replaced without being flashed, a bad connection at the PCM, TCM, or a bad TCM. Hope this helps.

Check engine light code p1698


A p1698 means the pcm is not recieving a bus message from the tcm. The vehicle bus is one wire that runs to each module as there means of communication. Could be a broken wire, bad connection, or possibly a bad module. Unless your pretty sure about what your doing and have some good wiring diagrams you should probably take it to your dealer.

A P1698 code is described as PCM Fault, No CCD Messages from TCM Conditions. It's triggered when the key is on, and the PCM did not detect any CCD messages from the Transaxle Control Module (TCM) for 10 seconds. Time for a trip to the dealer unless you feel like inspecting the wires & connectors leading to/from the TCM. Usually I tell people to go to the dealer when there are TCM problems! They can read any codes stored in the TCM that a regular code reader can't get. Good luck.
