Test D: Instrument Cluster Does Not Respond To Scan Tool
- Turn ignition switch to LOCK position. Disconnect instrument cluster harness connector C809. Inspect connector for loose, damaged or corroded terminals. Repair as necessary. If connector is okay, measure resistance between instrument cluster harness connector C809 terminal No. 13 (Gray/Violet wire) and DLC terminal No. 2 (Gray/Red wire). See Figure
and Fig 1
. If resistance is less than 5 ohms, go to step 3
. If resistance is 5 ohms or more, go to next step.
- Repair circuit between instrument cluster and DLC. See WIRING DIAGRAMS
. Repeat data link diagnostic test. See DATA LINK DIAGNOSTIC TEST
under SELF-DIAGNOSTIC SYSTEM.
- Reconnect all harness connectors and retest system. If symptom still exists, replace instrument cluster and repeat data link diagnostic test. See DATA LINK DIAGNOSTIC TEST
under SELF-DIAGNOSTIC SYSTEM. If symptom does not exist, system is okay at this time. Fault may be intermittent. Clear DTCs and repeat self-test.
