Immobilizer Control System Wiring Circuit Diagram:

Circuit Description
P1616 is detected when ECM detects different ID codes registered in ECM and keyless control module after turning engine start knob to ON position. Normally, when keyless start control module is replaced with new one, ECM automatically registers the applicable code in keyless start control module after turning ignition switch to ON position. However, when keyless start control module is replaced with used one, ECM does not automatically register the applicable code in keyless start control module even if ignition switch is turned to ON position.
