Cruise Main Switch, Coast/Set, Resume/ACCEL & Cancel Switch Circuit Check

Turn ignition off. Disconnect CC ECU harness connector. Measure resistance between CC ECU harness connector terminals No. 8 (Light Green/Red wire on Esteem; Light Green wire on Grand Vitara and Vitara) and No. 5 (Blue wire on Esteem; Black/Yellow wire on Grand Vitara and Vitara) with switches in specified position. See MULTIFUNCTION SWITCH ASSEMBLY RESISTANCE table. See Figure . If resistance is as specified, go to next step. If resistance is not as specified, go to step 3 .
Turn ignition on. Using DVOM, measure voltage between CC ECU harness connector terminal No. 8 (Light Green/Red wire on Esteem; Light Green wire on Grand Vitara and Vitara) and ground. With cruise control main switch off, voltage should be about zero volts. With cruise control main switch on, voltage should be 10-14 volts. If voltage is as specified, switch circuit is okay. If voltage is not as specified, go to next step.
Check cruise control main switch. See CRUISE CONTROL MAIN SWITCH under COMPONENT TESTS. Replace as necessary. If cruise control main switch tests okay, go to next step.
Check COAST/SET, RESUME/ACCEL and CANCEL switch operation. See COAST/SET, RESUME/ACCEL & CANCEL SWITCH ASSEMBLY under COMPONENT TESTS. Replace as necessary. If switch is okay, check for open or short in Black/Yellow wire and Light Green wire (Esteem) or Blue wire and Light Green/Red wire (Grand Vitara and Vitara) between multifunction switch and CC ECU. See WIRING DIAGRAMS . Repair as necessary.
