Have the following codes set on a friend's '96 Dodge
Intrepid, 3.3L, Auto trans. which are purported to be
serial communication link malfunction and a TCM
module issue, respectively: P0600 & P01698.

Any hints/leads/suggesstions would be appreciated.

Thanks in advance for your response and information.

John

Just guessing... I would say there is a computer for the transmission and
this computer is not "talking" to the main vehicle computer.

This could be because a fuse is blown which powers the transmission
computer. Or the wiring connecting the transmission computer to the rest of
the vehicle/main computer has a bad connection.

If any do-it-self wiring was done and then this problem occurred, return the
wiring to the way it was.

For fuse look in owners manual for which fuse and location for the
powertrain control module (they could call it something else?) fuse and or
check all fuses. How to check fuses...

If a wiring problem, complete troubleshooting instructions would be in a
*complete* factory service manual set of books. Complete includes service
manual, wiring diagrams, fuel and emissions books, etc. Order factory
service manual sets from your dealer.

No work has been done recently, I'm suspecting an issue
with the wiring harness to the TCM and will check it and
the fuse at my next opportunity.

Thanks for the input, Bill, much obliged.
