Cruise Control Cable Adjustment Procedure

1. Key ON, Engine OFF.

2. Enter diagnostics and select ECM override ES03 "ISC MOTOR".

3. Press the cooler button to retract the ISC to the minimum air throttle stop.

4. Note what servo blade hole the cruise cable is adjusted to.

5. Disconnect the cable from the servo blade.

6. Remove slack from cable (pull lightly on cable without moving throttle).

7. Reconnect the cable in the next loosest hole (closer to the throttle body). Be sure to reinsert the cable so that the retaining clip is toward the front of the car (see Figure 2).
8. If this hole is the same as the original adjustment, cruise cable adjustment is ok. Proceed with diagnosis.

9. If the new hole is different than the original adjustment, cruise cable was out of adjustment. Clear code E055 and proceed with minimum air RPM check.
