Immobilizer Control System: 10C-10
DTC P1615: Steering Lock Unit Communication Error
S6RW0CA304009
Wiring Diagram
Refer to “Immobilizer Control System Wiring Circuit Diagram”.
Circuit Description
When the transponder code in the ignition key is registered in ECM, the ID code is registered in both ECM and keyless
start control module at the same time. This DTC is detected only in case that the ID code cannot be registered in both
ECM and keyless start control module when the transponder code in the ignition key is registered in ECM.
NOTE
• Troubleshoot DTC P1618 first if both DTC P1615 and P1618 are detected at the same time.
• After replacing ECM, be sure to register the transponder code in the ignition key with ECM referring
to “Registration of the Ignition Key”. After replacing the keyless start control module of the vehicle
equipped with the keyless start system, be sure to perform “Registration of the Ignition Key”.

“DTC Check in Section 10E”.
Is DTC detected?
Go to applicable DTC
diag. flow.
Go to Step 5.
5
Check for communication circuit between steering lock
unit and keyless start control module
1) Check for open, short, and high resistance in steering
lock unit circuit. Refer to Step 2 in “DTC No. 11:
Communication Error with Steering Lock Unit in Section
10E”.
