Subaru Techline has received calls regarding inoperative RES (remote engine start) systems after installation.
Although technicians are able to successfully register the system, when attempting to start the vehicle with RES transmitters, there is no response from the vehicle. A quick check of the RES antenna will most likely show the connection is not fully seated.
When routing the RES antenna, verify that there is enough slack in the harness to tuck it under the headliner. If there is not enough slack, excessive pressure will be applied against the harness and disconnect the antenna. The RES antenna connection must be checked for full seating.
