Electronic Cruise Control (Actuator Test): Description and Operation

Actuator Test

The mechanical components of the cruise control can be checked by TECH 1 for correct functioning.

This is done by an actuator test which automatically checks the components.

If a malfunction is detected by the control unit, trouble code 55 is stored.

If no malfunction is detected, the fault may possibly be caused by a defect in the wiring harness or in one of the switches.

·    Service

Before replacing the control unit / actuator, use TECH 1 and the "System Checking with TECH 1; Opel / Vauxhall Omega - B 94 ECU" Checking Procedures or the multimeter / oscilloscope to check all input signals for correct nominal values.
