WARNING: This page is about a different car, the 2003 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
DTC applies only to models with standard type manual transaxle. There are 2 types of manual transaxles used. A standard type manual transaxle and a sequential manual transaxle. A standard type manual transaxle is a common transaxle in which the driver operates the clutch and shifts the transaxle. A sequential manual transaxle is an electronic controlled manual transaxle in which the clutch is operated and transaxle is shifted hydraulically by moving the shift lever forward or backward. The sequential manual transaxle may be identified by the shift lever pattern and uses a special fluid in the fluid reservoir. Shift lever pattern consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used.
