BME010266350204

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

Diagnostic procedure

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 CRUISE ACTUATOR REMOVAL/INSTALLATION)
No | Go to next step.
2 | INSPECT CRUISE CONTROL SWITCH • Inspect cruise control switch. (See CRUISE CONTROL SWITCH INSPECTION) • Is cruise control switch okay? | Yes | Go to next step.
No | Replace cruise control switch. (See AUDIO CONTROL SWITCH REMOVAL/INSTALLATION)
3 | INSPECT CLOCK SPRING • Inspect clock spring. (See CLOCK SPRING INSPECTION, CLOCK SPRING INSPECTION) • Is clock spring okay? | Yes | Go to next step.
No | Replace clock spring. (See 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 2E and ground? | Yes | Repair wiring harness.(cruise actuator-clock spring)
No | Repair wiring harness.(clock spring-ground)
