Toyota RAV4 (XA40) 2013-2018 Service Manual: Engine immobiliser system malfunction
Description
This dtc is output when one of the following occurs: 1) the ecm detects errors in its own communications with the transponder key ecu; 2) the ecm detects errors in the communication lines; or 3) the ecu communication id between the transponder key ecu and ecm is different and an engine start is attempted. Before troubleshooting for this dtc, make sure no transponder key ecu dtcs are present. If present, troubleshoot the transponder key ecu dtcs first.
