ANTI-THEFT SYSTEMS -

DTC NO. 11: TRANSPONDER COMMUNICATION SYSTEM OR RADIO INTERFERENCE OF ENCRYPTED CODE

NOTE: DTC P1610 will be set in PCM (A/T) or ECM (M/T) when DTC 11 is set in immobilizer ECU.
1. Check for immobilizer type keys for other vehicles near ignition switch (on key ring). If other immobilizer keys are present, remove keys and try starting vehicle again. If no other immobilizer keys are present, go to next step.

2. Attempt to start vehicle using a different ignition key programmed to vehicle. If engine starts, replace defective ignition key and reprogram. If vehicle does not start, go to next step.

3. Recheck for DTCs. If DTC 11 is set, go to next step. If DTC 12 is set, go to DTC NO. 12: ENCRYPTED CODES DO NOT MATCH OR ARE NOT REGISTERED.

4. Access, but do not disconnect, ignition key ring antenna connector. Using DVOM, backprobe and measure resistance between ignition key ring antenna connector terminals No. 3 (White/Blue wire) and No. 7 (White/Red wire). If resistance is less than 2 ohms, go to next step. If resistance is 2 ohms or greater, replace ignition key ring antenna. See IGNITION KEY RING ANTENNA under REMOVAL & INSTALLATION. Recheck for DTC 11.

5. Locate immobilizer ECU. Check for poor connections at immobilizer ECU connector terminals. If poor connections are found, repair as necessary. Recheck for DTC 11. If connections are okay, go to next step.

6. Check for faulty White/Blue wire between ignition key ring antenna connector terminal No. 3 and immobilizer ECU connector terminal No. 10. Check for faulty White/Red wire between ignition key ring antenna connector terminal No. 7 and immobilizer ECU connector terminal No. 11. If faulty circuit is found, repair as necessary. Recheck for DTC 11. If circuits are okay, replace immobilizer ECU.
