  If the vehicle has a manual transaxle, use an

ohmmeter to check continuity between the DK
GRN/WHT wire at the VSS and terminal 10 of
the cruise control actuator connector.

S

  If the vehicle has an automatic transaxle,

check the continuity of the following wires:

– The YEL wire between cruise control ac-
tuator connector terminal 10 and VSS con-
nector terminal A.
