N OT E
Use this procedure to troubleshoot an suspect problems with CAT Data Link.
y
Use this procedure to troubleshootsystem when one of following diagnostic codes is active or eas-
ily repeated:
a. 296-09 Unable to communicate with Transmission ECM
b. 296-12 Transmission ECM Failed
c. 596-09 Unable to communicate with Implement ECM
d. 596-12 Wrong Response from Implement ECM
This procedure checks for an opencircuit or for a short circuit in CAT Data Link. If you are expe-
riencing problems with communications between ET and ECM, refer to WP 0008 00.
CAT Data Link is standard daa link used by ECM to communicate with ET. ECM communicates
t
with ET to share status information and diagnostic information. ET can also be used to configure
ECM parameters. This information will not be available if communication fails between ECM
and ET.
