⁽¹⁾	Some codes are two-trip detection logic code(s). For more information, see TWO-TRIP DETECTION LOGIC in SELF-DIAGNOSTICS - INTRODUCTION article.

⁽²⁾	These codes are for models equipped with engine immobilizer system. MIL will not illuminate. For testing procedures, see appropriate ENGINE IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.

⁽³⁾	If this code is set, ECM will enter fail-safe mode.

⁽⁴⁾	These codes only apply to models with electronically controlled transmissions. For testing procedures, see appropriate ELECTRONIC CONTROLS article in AUTOMATIC TRANSMISSIONS.

⁽⁵⁾	MIL will not illuminate.
