Integrated Memory System Control Switch

Remove Integrated Memory System (IMS) control switch from driver's door. Disconnect harness connector. Check for continuity and measure resistance between specified terminals with switch in specified position. See Fig 1 . See IMS CONTROL SWITCH TEST table. See WIRING DIAGRAMS . If continuity and/or resistance does not exist as specified, replace IMS control switch.
