DTC 21 Cruise control switch (SET/COAST switch)
DETECTION
CONDITION
• Resistance detected between cruise actuator connector terminal J and ground is other than
approximately 680 ohms.
POSSIBLE
CAUSE
• Cruise actuator malfunction
• Cruise control switch malfunction
• Clock spring malfunction
• Open circuit in wiring harness between clock spring and ground
• Open or short circuit in wiring harness between cruise actuator and clock spring
STEP INSPECTION ACTION
1 INSPECT SIGNAL LINE OF CRUISE
CONTROL SWITCH POSITION
• Disconnect cruise actuator connector.
• Turn SET/COAST switch on.
• Is resistance at cruise actuator connector
terminal J approximately 680 ohms?
Yes Replace cruise actuator.
(See T–110 CRUISE ACTUATOR REMOVAL/
INSTALLATION)
No Go to next step.
2 INSPECT CRUISE CONTROL SWITCH
• Inspect cruise control switch.
(See T–116 CRUISE CONTROL SWITCH
INSPECTION)
• Is cruise control switch okay?
Yes Go to next step.
No Replace cruise control switch.
(See T–115 CRUISE CONTROL SWITCH REMOVAL/
INSTALLATION)
3 INSPECT CLOCK SPRING
• Inspect clock spring.
(See T–126 CLOCK SPRING INSPECTION)
• Is clock spring okay?
Yes Go to next step.
No Replace clock spring.
(See T–125 CLOCK SPRING REMOVAL/INSTALLATION)
4 INSPECT WIRING HARNESS BETWEEN
CLOCK SPRING AND GROUND FOR
CONTINUITY
• Disconnect cruise control switch connector.
• Is there continuity between clock spring
connector terminal C and ground?
Yes Repair wiring harness. (cruise actuator—clock spring)
No Repair wiring harness. (clock spring—ground)
DTC 22 Cruise control switch (RESUME/ACCEL switch)
DETECTION
CONDITION
• Resistance detected between cruise actuator connector terminal J and ground is other than
approximately 2.2 kilohms.
POSSIBLE
CAUSE
• Cruise actuator malfunction
• Cruise control switch malfunction
INSPECTION ACTION
INSPECT CRUISE CONTROL SWITCH
