Test J: DEACTIVATOR Switch Circuit Failure (Flash Code 3)

NOTE: This test only applies to vehicle equipped with electronic instrument clusters.

NOTE: Perform all voltage and resistance tests using a Digital Volt-Ohm Meter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.

Check brakelights for proper operation. If brakelights operate properly, go to next step. If brakelights do not operate properly, repair brakelights as necessary. See EXTERIOR LIGHTS in SYSTEM WIRING DIAGRAMS article in ELECTRICAL. After repair, test system for normal operation.
Turn ignition switch to LOCK position. Disconnect cruise control servo/actuator 10-pin harness connector C122. Cruise control servo/actuator harness connector C122 is located at left rear engine compartment. See Figure. Measure voltage between cruise control servo/actuator harness connector C122 terminals No. 9 (Orange wire) and No. 10 (Pink/Orange wire). See Figure. See WIRING DIAGRAMS . If voltage is 10 volts or less, go to next step. If voltage is greater than 10 volts, replace cruise control servo/actuator. See SERVO/ACTUATOR ASSEMBLY under REMOVAL & INSTALLATION. After repair, test system for normal operation.
Ensure ignition switch is on LOCK position. Disconnect cruise control deactivator switch 3-pin harness connector C277. Cruise control deactivator switch harness connector C277 is located on brake pedal support. See Figure. Connect a fused jumper wire between cruise control deactivator switch harness connector C277 terminals No. 1 and 2. See Figure. Measure voltage between cruise control servo/actuator harness connector C122 terminals No. 9 (Orange wire) and No. 10 (Pink/Orange wire). See Figure. See WIRING DIAGRAMS . If voltage is 10 volts or less, go to next step. If voltage is greater than 10 volts, replace cruise control deactivator switch. See DEACTIVATOR SWITCH under REMOVAL & INSTALLATION. After repair, test system for normal operation.
Measure resistance between cruise control servo/actuator harness connector C122 terminal No. 9 and cruise control deactivator switch harness connector C277 terminal No. 2 (Orange wire). If resistance is 5 ohms or less, repair open circuit in Light Green/Red wire between cruise control deactivator switch and Central Junction Box (CJB). CJB is located under left side of dash panel. See Figure. See WIRING DIAGRAMS . If resistance is greater than 5 ohms, repair open circuit in Orange wire between cruise control servo/actuator and cruise control deactivator switch. After repair, clear DTC and test system for normal operation.
