Gr II (Speed Control II): Diagnosis/Encoding
Diagnosis of the GR II system is carried out with the DIS tester. The cruise control module stores faults that occur with the input/output signals for cruise control operation. The Multi-Function steering wheel control module stores faults that occur with the cruise control switch.
There is only one control module for all model versions that use the new GR II system. Encoding is required if the control module is changed. To code a new control module, go to the coding application in DIS and carry out a coding procedure as stated on the screen.
An uncoded module will allow limited cruise control operation.
