Sounds like you may have the dash cluster solder problem. Here's a link to some pictures of what needs to be done, but if you google Caravan dash soldering, or similar, there is more details out there.

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.

SOURCE: What does the Diagnostic error

First, remove battery negative cable.Then I would remove kick panel (by right foot when sitting) on passenger side & locate BCM (body control module) . remove the harness connector to it & spray well with contact cleaner in connector & on module where they meet. Let it dry a bit, then re-connect it & re-connect negative battery terminal, and see if that helps. It's not unusual for these codes to come up & make one think that a part needs to be replaced, when it's just a bad connection.

you need to go over your entire wiring harness, under the hood and inside the dash. Start with the ground wire on the battery and work your way inside. It sounds like there is a loose ground wire somewhere

My dashboard lights and rear running lights arent working. The brake lights work and the check engine soon, change oil, etc lights are on but the lights for the speedometer and tachometer arent on.

The dash and running lights may be part of your headlight switch is bad. Check engine soon does not mea to change the oil. It means there is an issue with something having to do with the PCM and any of its related parts on the engine and/or transmission.
Need to have a code reader hooked up and see what code(s) are in the system.

Signal light??? Do you mean check engine light or service engine soon light? If so you will need to have the codes pulled to determine the issue.

My nissan frontier crew cab 2001 SERVICE ENGINE SOON light on the dashboard kept flashing. Have serviced the engine, but the light won't stop flashing. Thanks

That means you have a failure somewhere in the system (Powertrain, Chassis, Body, Network). Just because the engine was serviced doesn't mean anything. You need to have the diagnostic codes pulled to determine what is causing the light to be triggered. Then correct the problem and the light will go out. If you just erase the light or code it wont solve anything.

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.

Service engine light soon on for serveic how do i turn it off

You can go to any auto parts store, ask to barrow an OBD-II Code reader. Plug it into your cars computer data port (Usually on the dashboard, on the drivers side, close to the lower portion of the dash) and push erase.
However, you should find out what the computer is telling you first, and/or fix the problem. Engine service lights, run on a circuit that only completes itself once every 20-30 times you start your car. This means, if you were to just erase the engine code, the light will go off, but will just turn back on eventually.
