10C-51 Immobilizer Control System: For Diesel Engine Model
Step
4 CAN communication circuit check
1) Check for open, short and high resistance in CAN
communication circuit between ECM and keyless start
control module.
Is each CAN communication circuit in good condition?
5 Check of keyless start control module power and
ground wire circuits
1) Check keyless start control module power and ground
wire circuits referring to "Keyless Start Control Module
Power and Ground Circuit Check in Section 10E".
Are they in normal?

DTC B1717: Unregistered Keyless Start Control Module

Circuit Description
B1717 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 ID 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 ID
code in keyless start control module even if ignition switch is turned to ON position.
