tor pedal position is contin-
ued to be large.Vehicle is driven at the higher speed than set vehicle
speed for an extremely long time (approx. 10 minutes)
during cruise driving.This DTC is indicated
when running for a long
time at the higher speed

sible.During cruise driving, set vehicle speed cannot be main-
tained for some reasons such as sharp upslope, parking
brake and engine output abnormal decrease.This DTC is indicated

switch and fuse &
relay box.
 Check the clutch
switch and circuit.
3 CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH CIRCUIT.

ness connector terminal and stop light switch
and brake switch harness connector terminal.
Connector & terminal
(B136) No. 8 — (B65) No. 3:
(B136) No. 9 — (B65) No. 4: Is the resistance less than 10
Ω? Go to step 4.Repair the har-
ness.
4 CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH.
