Test J: DEACTIVATOR Switch Circuit Failure (Flash Code 3)
NOTE:
This test only applies to vehicle equipped with electronic instrument clusters.
- Check brake light operation. If brake lights operate, go to next step. If brake lights do not operate, repair brake lights as necessary. See EXTERIOR LIGHTS article.
- Turn ignition switch to OFF position. Disconnect cruise control servo/actuator harness connector C234. Turn ignition switch to RUN position. Measure voltage between terminals No. 9 (Orange wire) and No. 10 (Pink/Orange wire) at cruise control servo/actuator harness connector C234. See Figure . If battery voltage does not exist, go to next step. If battery voltage exists, replace cruise control servo/actuator. See SERVO/ACTUATOR ASSEMBLY under REMOVAL & INSTALLATION.
- Turn ignition switch to OFF position. Disconnect cruise control deactivator switch harness connector C233. Turn ignition switch to RUN position. Connect a fused jumper wire between terminals at cruise control deactivator switch harness connector C233. Measure voltage between terminals No. 9 (Orange wire) and No. 10 (Pink/Orange wire) at cruise control servo/actuator harness connector C234. If battery voltage does not exist, go to next step. If battery voltage exists, replace cruise control deactivator switch. See DEACTIVATOR SWITCH under REMOVAL & INSTALLATION.
- Turn ignition switch to OFF position. Measure resistance in Orange wire between cruise control deactivator switch harness connector C233 and terminal No. 9 at cruise control servo/actuator harness connector C234. If resistance is 5 ohms or less, repair open in Light Green/Red wire. If resistance is greater than 5 ohms, repair open in Orange wire.
