DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION

SELECTOR LEVER OPERATION CHECK

1. Shift the selector lever to each range and check to see that the lever moves smoothly and is controlled. Check to see that the position indicator is correct.
2. Check to be sure that the selector lever can be shifted to each position.
3. Start the engine and check to see if the vehicle moves forward when the selector lever is shifted from "N" to "D" and moves backward when shifted to "R".
4. When the shift lever malfunctions, adjust the control cable and the selector lever sleeve. Check for worn shift lever assembly sliding parts.

Scheme 44

Scheme 45

1. Place selector lever in "N" (Neutral) position.
2. Loosen the manual control lever lock nut to separate the cable and lever.
3. Place the manual control lever in the "N" (Neutral) position.
4. Turn the transaxle range switch body until the 12 mm (0.47 in.) wide end of the manual control lever aligns with the switch body flange [12 mm (0.472 in.) wide portion].
5. Tighten the attaching bolts (2 pcs.) to the specified torque. Transaxle Range Switch Attaching Bolt: 10-12 N.m (100-120 kg.cm, 7-9 lb.ft) NOTE: When setting up the switch body, be careful that the O-ring does not drop from the switch body. Tighten the attaching bolts carefully.
6. Make sure that the selector lever is in the "N" (Neutral) position.
7. Adjust the flange nut so that there is no slack in the control cable and make sure that the selector lever operates smoothly.
8. Run the vehicle and confirm that the transaxle is set in each range when the selector lever is shifted to each position.
