⁽¹⁾	Check power source circuit. See POWER SOURCE CIRCUIT under SYSTEM TESTS.

⁽²⁾

Check for opens and shorts in wiring harness and electrical connectors for engine immobilizer system and perform pin voltage tests at Engine Control Module (ECM). See WIRING DIAGRAMS and PIN VOLTAGE TESTS . ECM is located behind passenger's side kick panel, just below instrument panel. See Figure. Repair or replace components as necessary.

⁽³⁾	Ensure ignition key which did not start the engine has been registered and that it is possible to start the engine with other already registered ignition keys. See PROGRAMMING for information on ignition key registration.

⁽⁴⁾	Transponder key amplifier may be defective, or wiring circuit between ECM and transponder key amplifier may be defective. Transponder key amplifier is located near upper steering column bracket. See Figure.

⁽⁵⁾	Check that automatic registration mode is completed. If still in automatic registration mode, SECURITY indicator light may remain on. See IGNITION KEY REGISTRATION under PROGRAMMING for information on automatic registration mode.

⁽⁶⁾	Check SECURITY indicator light circuit. See SECURITY INDICATOR LIGHT CIRCUIT under SYSTEM TESTS.
