ASCD Hold Relay Circuit Check

Check Relay Power Circuit - Remove ASCD hold relay. Turn ignition on. Measure voltage between ASCD hold relay harness connector terminal No. 5 and ground. See Fig 1 or Fig 2 . If battery voltage exists, go to next step. If battery voltage does not exist, repair open or short in circuit between fuse and ASCD hold relay. See WIRING DIAGRAMS .

Check Relay Ground Circuit - Turn ignition off. Check continuity between ASCD hold relay harness connector terminal No. 2 and chassis ground. If continuity exists, go to next step. If continuity does not exist, repair open ground circuit. See WIRING DIAGRAMS .

Check Hold Relay Circuit - Measure continuity between ASCD hold relay harness connector terminals as specified. See HOLD CIRCUIT TEST table. See Fig 1 or Fig 2 . If continuity does not exist between specified terminals, go to next step. If continuity exists between specified terminals, replace ASCD hold relay.

HOLD CIRCUIT TEST

Application	Relay Terminals No.
A/T	1 & 3; 1 & 6
M/T	1 & 3

Check cruise control main switch. See MAIN SWITCH TEST under COMPONENT TESTS. Replace main switch if necessary. If main switch is okay, ASCD hold relay circuit is okay.
