(1) Some DTCs are two-trip detection logic code(s). For more information, see TWO-TRIP DETECTION LOGIC  under SELF-DIAGNOSTIC SYSTEM.
(2) These DTCs are for engine immobilizer system. MIL will not illuminate. For testing procedures, see appropriate ENGINE IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.
(3) If this DTC is set, ECM will enter fail-safe mode.
(4) These DTCs only apply to models with electronically controlled transmissions. For testing procedures, see appropriate ELECTRONIC CONTROLS article in AUTOMATIC TRANSMISSIONS.
(5) MIL will not illuminate.
