Code P1698 means
* P1698 PCM Failure EEPROM Write Denied
* P1698 -No CCD messages from the Transmission or Body Control Module (TCM or BCM) Probably needs a new PCM (Aka computer or ECU)
My P 1698 stated
"Manufacturer Contrl
Auxillary inputs
Auxillary Outputs"
?any thoughts as I have had the same prob with first, intermittent dashboard display failure, now with Service Vehicle Soon light and ABS light always on.
so does your speedometer and all other gauges quit working from time to time? Cause I have a fix for that and it might take care of all your problems. Let me know
Ron, I know this post is several years old, but I am having the same problem you describe above. All my gauges fail at one time and stay like that. It happens intermittently, as you say above, and now I have a P1698 code.
Randy what did u do to fix problem
hold down reset til codes Show on miles glass then push reset and you will see speed
meter and tach and gauges Run test if it doesnt probably the output speed sensor by drivers side behind tire screwed in by 1 inch socket
it runs speed meter the other is for tach meter which is under two lines under air box
What could I do to fix this on my 1998 Grand Dodge caravan.Work P1698 is what came out on the check engine llite?
