10A-3 Cruise Control System: 

Cancel Conditions of Cruise Control System

S5JB0AA101003

Constant cruising is cancelled under the following 
conditions.
• *Ignition switch is turned OFF.
• MAIN switch is turned OFF.
• Vehicle speed becomes lower than minimum 

operating speed (40 km/h (25 mile/h)).

• *Vehicle speed varies beyond cancel speed range (–

10 km/h (–6 mile/h)) from preset speed.

• *Brake pedal is depressed. (Brake light switch is 

turned ON).

• *Clutch pedal is depressed (Clutch pedal position 

switch is turned ON) (For M/T vehicle).

• *Selector lever is shifted to “P”, “R” or “N” range.
• *CANCEL switch is turned ON.

NOTE
When constant cruising is cancelled under 
any condition with * (asterisk), vehicle speed 
before cancellation can be resumed by 
operating RES/ACC switch, provided that 
vehicle speed is higher than 40 km/h (25 mile/
h).

Diagnostic Information and Procedures

Cruise Control System Symptom Diagnosis

S5JB0AA104001

NOTE

• ECM uses TCM, ABS hydraulic unit/control module and CAN communication to transmit and receive 

data for cruise control. Therefore, check that no DTC is detected from ECM, TCM or ABS hydraulic 
unit / control module before performing this Cruise Control System Symptom Diagnosis. If DTC is 
detected, correct trouble indicated by that DTC first.

• Check each part in the order from the top of the following list.

Cruise Control System:  10A-6

Inspection of Cruise Control System Circuit

S5JB0AA104012

Cruise control system is controlled by ECM. Each switch and circuit can be checked by taking measurement of 
terminal voltage and terminal to terminal resistance of ECM. When measuring these values, be sure to read 
precautions for measurement described under “Inspection of ECM and Its Circuits in Section 1A”.

Voltage Check
Check voltage between the following terminals with ECM connector connected.
