(1) Some DTCs are two-trip detection logic DTCs. For more information, see TWO-TRIP DETECTION LOGIC under SELF-DIAGNOSTIC SYSTEM. (2) DTC applies to models equipped with engine immobilizer system. MIL will not illuminate if DTC exists. For testing procedures, see appropriate ENGINE IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT. (3) MIL will not illuminate. (4) If this DTC is set, Engine Control Module (ECM) will enter fail-safe mode. (5) DTC applies only to models with standard type manual transaxle. (6) There are 2 types of manual transaxles used. A standard type manual transaxle and a sequential manual transaxle. Standard type manual transaxle is a common transaxle in which the driver operates the clutch and shifts the transaxle. Sequential manual transaxle is an electronically controlled manual transaxle in which the clutch is operated and transaxle is shifted hydraulically by moving the shift lever forward or backward. Sequential manual transaxle may be identified by shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used. (7) Applies to models with sequential manual transaxle.
