Test R - Improper High Beam Indicator Operation
- Turn headlights on. Operate high beams. If high beams operate properly, go to next step. If high beams do not operate properly, see EXTERIOR LIGHTS article.
- Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER
under REMOVAL & INSTALLATION. Remove high beam indicator light bulb. Check continuity between terminals of bulb. If continuity exists, go to next step. If continuity does not exist, replace high beam indicator light bulb.
- Disconnect instrument cluster electrical connector C3. See Figure
. Disconnect multi-function switch connector C1, or Daytime Running Lights (DRL) control connector. See Fig 1
.
- Measure resistance between instrument cluster harness connector C3, terminal No. 10 (Red/White wire) and multi-function switch connector C1, terminal No. 1 (Red/White wire) or DRL control connector No. 3 (Red/White wire). See Fig 1
. Resistance should be less than 5 ohms. If resistance is less than 5 ohms, replace instrument printed circuit and gauge contact clips. See PRINTED CIRCUIT
under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair Red/White wire. See WIRING DIAGRAMS
