DIAGNOSTIC TROUBLE CODE PROCEDURES
DTC 11: Transponder Communication System or Radio Interference of Encrypted Code.
.
CIRCUIT OPERATION
The ignition key is powered by the ignition key ring
antenna. The ignition key then sends an encrypted
code. The ignition key ring antenna receives the
encrypted code, and determines if the ignition key is
registered.
.
DTC SET CONDITION
• DTC 11 may be output if other ignition keys are in
the vicinity of the vehicle as it is being started.
• The transponder’s encrypted code is not sent to
the immobilizer-ECU immediately after the igni-
tion switch is turned to "ON" position.
NOTE: DTC 11 is always output together with MFI
system DTC P0513.
.
TROUBLESHOOTING HINTS
• Radio interference of the encrypted code
• Malfunction of the transponder
• Malfunction of the immobilizer-ECU.
