Test C: Flash Code 3 - DEACTIVATOR Switch Circuit Failure
- Turn ignition switch to LOCK position. Disconnect cruise control servo harness connector. Turn ignition switch to RUN position. Measure voltage between terminal No. 4 (Tan/Light Blue wire) and terminal No. 10 (Pink/Orange wire) at cruise control servo harness connector. See Figure . If voltage is 10 volts or less, go to next step. If voltage is greater than 10 volts, replace cruise control servo. Perform SELF-DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM.
- Turn ignition switch to LOCK position. Disconnect deactivator (brake pressure) switch harness connector. Turn ignition switch to RUN position. Measure voltage between ground and Light Green/Red wire terminal at deactivator switch harness connector. If voltage is 10 volts or less, go to next step. If voltage is greater than 10 volts, replace deactivator switch and perform SELF-DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM.
- Measure resistance in Black/Yellow wire between terminal No. 9 at cruise control servo harness connector and deactivator switch harness connector. If resistance is 5 ohms or less, repair Light Green/Red wire between deactivator switch and instrument panel fuse box. If resistance is greater than 5 ohms, repair open in Black/Yellow wire between cruise control servo and deactivator switch. After repair, perform SELF-DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM.
