STEP INSPECTION ACTION
1 INSPECT BRAKE SWITCH
• Disconnect brake switch connector.
• Inspect brake switch.
(See P–8 BRAKE SWITCH INSPECTION)
• Is brake switch okay?
Yes Go to next step.
No Replace brake switch.
2 INSPECT BRAKE SWITCH 2
• Inspect brake switch 2.
(See P–8 BRAKE SWITCH INSPECTION)
• Is brake switch okay?
Yes Go to next step.
No Replace brake switch.
3 INSPECT WIRING HARNESS BETWEEN
BRAKE SWITCH AND CRUISE ACTUATOR
FOR CONTINUITY
• Disconnect cruise actuator connector.
• Is there continuity between brake switch
connector D and cruise actuator connector
C.
Yes Go to next step.
No Repair wiring harness. (Cruise actuator—Brake switch)
4 INSPECT WIRING HARNESS BETWEEN
BRAKE SWITCH 2 AND CRUISE ACTUATOR
FOR SHORT TO POWER SUPPLY
• Connect brake switch connector.
• Turn ignition switch ON position.
• Is voltage at cruise actuator connector
terminal K approximately 12 V?
Yes Replace cruise actuator.
(See T–110 CRUISE ACTUATOR REMOVAL/
INSTALLATION)
No Repair wiring harness. (Cruise actuator—Brake switch 2)
DTC 11 Cruise control switch (SET/COAST switch)
DETECTION
CONDITION
• Resistance detected between cruise actuator connector terminal J and ground is always
approximately 680 ohms.
POSSIBLE
CAUSE
• Cruise actuator malfunction
• Cruise control switch malfunction
INSPECTION ACTION
INSPECT DTC FOR OPERATION MODE
• Was operation mode for DTC 21 performed?
Yes Perform operation mode for DTC 21 on-board diagnostic
again. Even if no malfunction is detected in operation mode,
if DTC 11 is indicated in condition detection mode on-board
diagnostic, replace cruise actuator.
(See T–110 CRUISE ACTUATOR REMOVAL/
INSTALLATION)
No Perform operation mode for DTC 21.
DTC 12 Cruise control switch (RESUME/ACCEL switch)
DETECTION
CONDITION
• Resistance detected between cruise actuator connector terminal J and ground is always
approximately 2.2 kilohms.
POSSIBLE
CAUSE
• Cruise actuator malfunction
INSPECTION ACTION
INSPECT DTC FOR OPERATION MODE
• Was operation mode for DTC 22 performed?
Yes Perform operation mode for DTC 22 on-board diagnostic
again. Even if no malfunction is detected in operation mode,
if DTC 12 is indicated in condition detection mode on-board
diagnostic, replace cruise actuator.
(See T–110 CRUISE ACTUATOR REMOVAL/
INSTALLATION)
No Perform operation mode for DTC 22.
