DTC Confirmation Procedure1) Register the transponder code in the transponder in the ignition key with ECM referring to “Registration of the
Ignition Key”.
2) Check DTC in ECM.
Troubleshooting
DTC P1616: Different Registration ID Codes (Vehicle equipped with keyless start system only)S7RS0BA304010
Circuit Description
P1616 is detected when ECM detects different ID codes registered in ECM and keyless start control module after
turning engine start knob to ON position.
Normally, when keyless start control module is replaced with new one, ECM automatically registers blank ID code of
keyless start control module to applicable one after turning ignition switch to ON position.
However, when keyless start control module is replaced wit h used one, ECM does not automatically register old ID
code of keyless start control module to applicable one ev en if ignition switch is turned to ON position.
Step Action Yes No
1 Was “Immobilizer Control S ystem Check” performed? Go to Step 2. Go to “Immobilizer
Control System Check”.
2 Registration of Ignition Key
1) Register ignition key in use with ECM referring to
“Registration of the Ignition Key”.
Was registration of ignition key completed? Unregistration of remote
controller ID code.
Go to Step 3.
3 DTC check of ECM
Is DTC detected other than P1615? Go to applicable DTC
diag. flow.
Go to Step 4.
4 DTC check of keyless start control module
1) Check keyless start control module for DTC referring to
“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) With the ignition switch at OFF position, disconnect
steering lock unit connector and keyless start control
module connector.
2) Check for proper connection at terminals and wires of
each connector referring to “Intermittent and Poor
Connection Inspection in Section 00”.
3) If OK, check for open, short, and high resistance in each circuit between steering lock unit and keyless start
control module. Refer to step 2 in “DTC No. 11:
Communication Error with Steeri ng Lock Unit in Section
10E”.
Is each circuit in good condition? Go to Step 6. Repair malfunction part.
6 Steering lock unit power supply check
1) Connect keyless start control module connector.
2) With ignition switch at ON position, check voltage
between power supply terminal and ground terminal of
steering lock unit connector.
Is voltage 4 – 6 V? Replace steering lock
unit.
Substitute a known-
good keyless start
control module and
recheck. If DTC P1615
is still detected,
substitute a known good
ECM and recheck.
