CRUISE CONTROL SYSTEM (DIAGNOSTICS)

32

Cruse Control out of
Range

• Controlled vehicle speed decreased under the
limit during cruising.
• Set operation was performed at vehicle speed
unavailable for setting.
• RESUME operation was performed without
memorized vehicle speed.

This code is displayed, though the
vehicle speed is increased to the
speed available for cruise set and
set operation was performed again.
<Ref. to CC(diag)-23, 32, Diagnostic
Procedure with Cancel Code.>

34

Prohibition of cruise
control at continuing big
Accel. angle

The vehicle has been driven at higher speed than
set vehicle speed for an abnormally long time
(approximately 10 minutes) during cruise driving.

This code is displayed when driving
for a long period of time at higher
speed than appropriate cruise set
vehicle speed by operating accelera-
tor pedal. In this case, the cruise
setting is deactivated. <Ref. to
CC(diag)-24, 34, Diagnostic Proce-
dure with Cancel Code.>

35

Prohibition of cruise
control at vehicle speed
F/B malfunction

Set vehicle speed cannot be kept because of some
reasons (steep uphill, parking brake, abnormal
decrease of engine output, etc.) during cruise driv-
ing.

This code is displayed when driving
condition is not suitable for cruise
control. Perform cruise set operation
again after clearing the possible
cause. <Ref. to CC(diag)-24, 35,
Diagnostic Procedure with Cancel
Code.>

41

VDC/TCS Operating

Vehicle dynamics control (VDC) or TCS is oper-
ated during cruise driving or cruise setting.

This code is displayed when driving
condition is not suitable for cruise
control. Perform cruise set operation
again after clearing the possible
cause. <Ref. to CC(diag)-24, 41,
Diagnostic Procedure with Cancel
Code.>

43

ABS/VDC Failure

ABS or Vehicle dynamics control (VDC) system
malfunction is detected during cruise driving or
cruise setting.

<Ref. to CC(diag)-24, 43, Diagnostic
Procedure with Cancel Code.>

44

Body Integrated unit
Failure

Body integrated unit system malfunction is
detected during cruise driving or cruise setting.

<Ref. to CC(diag)-24, 44, Diagnostic
Procedure with Cancel Code.>

45

Meter Failure

Combination meter malfunction is detected during
cruise driving or cruise setting.

<Ref. to CC(diag)-24, 45, Diagnostic
Procedure with Cancel Code.>

61

Brake switch abnormal

Malfunction in the stop light & brake switch is
detected.

<Ref. to CC(diag)-24, 61, Diagnostic
Procedure with Cancel Code.>

62

Neutral Switch Failure

Neutral position switch malfunction is detected.

<Ref. to CC(diag)-24, 62, Diagnostic
Procedure with Cancel Code.>

63

Abnormality of change
in vehicle speed

Malfunction of vehicle speed signal variation is
detected.

<Ref. to CC(diag)-25, 63, Diagnostic
Procedure with Cancel Code.>

64

Engine Sensor Failure 1 Malfunction related to engine is detected.

<Ref. to CC(diag)-25, 64, Diagnostic
Procedure with Cancel Code.>

65

Abnormality 1 of
switches related to
cruise control

Cruise control command switch malfunction is
detected. (When the switch is pressed ON for a
long time (approximately two minutes), stuck ON
condition is detected.)

<Ref. to CC(diag)-25, 65, Diagnostic
Procedure with Cancel Code.>

66

Cruise Control Calcula-
tion Error

Cruise control calculation (microcomputer) mal-
function is detected.

CHECK CRUISE CONTROL COMMAND
SWITCH CIRCUIT.
1) Remove the driver’s airbag module. <Ref. to
AB-15, REMOVAL, Driver’s Airbag Module.>
2) Disconnect the harness connector of cruise
control command switch.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.

Connector & terminal

(ST3) No. 8 (+) — Chassis ground (–):
(ST3) No. 7 (+) — Chassis ground (–):

Is the voltage 5 V or more?

Go to step

2.

Check the harness
between cruise
control command
switch and ECM,
and the steering
roll connector for
open or short cir-
cuit, or for poor
contact.
