ON-BOARD DIAGNOSTIC [CRUISE CONTROL SYSTEM]
STEP
* 7 VERIFY WHICH IS MALFUNCTIONING‚
CRUISE ACTUATOR AND WIRING HARNESS
(BRAKE SWITCH 2 AND CRUISE
ACTUATOR) OR BRAKE SWITCH 2
• Disconnect brake switch connector.
• Turn ignition switch ON position.
• Is voltage at brake switch connector terminal
B approximately 12 V?
* 8 INSPECT WIRING HARNESS BETWEEN
BRAKE SWITCH 2 AND CRUISE ACTUATOR
FOR SHORT TO POWER SUPPLY
• Turn ignition switch to LOCK position.
• Disconnect cruise actuator connector.
• Turn ignition switch ON position.
• Is voltage at cruise actuator connector
terminal K approximately 12 V?
End Of Sie
DTC 35
DTC 35 Clutch switch (MTX), TR switch (ATX)
DETECTION
• Voltage detected at cruise actuator connector terminal F is not approximately 0 V.
CONDITION
• Cruise actuator malfunction
• Starter relay malfunction (ATX)
• Clutch switch malfunction (MTX)
POSSIBLE
• TR switch malfunction (ATX)
CAUSE
• Open circuit in wiring harness between PCM and clutch switch (MTX)
• Open circuit in wiring harness between starter relay and TR switch (ATX)
• Open circuit in wiring harness between cruise actuator and clutch switch (MTX) or TR switch (ATX)
Diagnostic procedure
STEP
• Does vehicle has MTX?
1
2 INSPECT CLUTCH SWITCH
Is clutch switch okay?
* 3 INSPECT WIRING HARNESS BETWEEN
CLUTCH SWITCH AND GROUND FOR
CONTINUITY
• Disconnect clutch switch connector.
• Is there continuity between clutch switch
connector terminal B and ground?
* 4 INSPECT WIRING HARNESS BETWEEN
CRUISE ACTUATOR AND CLUTCH SWITCH
FOR CONTINUITY
• Disconnect cruise actuator connector.
• Is there continuity between cruise actuator
connector terminal F and clutch switch
connector terminal A?
