What do you use the can cable for? Tazer of something?I was able to get some Jeep warrantee done, the service advisor asked about the W12 update and I told him "not today", he annotated on computer not to do the update. No issues. The funny thing I left the JLScan cable and module plugged into the OBDII port to see what they would say. Got Jeep repaired and washed and told to have a great weekend.
