Adjustment Procedure


    Object Number: 863170  Size: SH

    Important: While adjusting the transaxle range switch, always rotate the switch towards the engine to achieve continuity. A diagnostic trouble code DTC P0706 could result if this procedure is not followed.

    Important: Digital volt/ohm meter (DVOM) with audible continuity test is preferred. Do not stick the probe in the transaxle range switch terminal hole; use male terminals on the transaxle range switch or faulty readings could occur.

  1. Place the transaxle in Drive (D). Use an ohmmeter or continuity tester to check for continuity across terminals on the selector switch. Rotate the transaxle range switch from the left fender towards the engine until continuity is achieved.
  2. Notice: Refer to Fastener Notice in the Preface section.

  3. Tighten the switch-to-case bolts. After switch-to-case bolts have been tightened, check continuity.
  4. Tighten
    Tighten the transaxle range switch-to-case bolts to 14 N·m (10 lb ft).
