Hazard Warning Switch Test

Ensure flasher is okay. Using DVOM, ensure switch continuity exists between 22-pin Center (A/C) ECU connector terminals No. 3 and No. 22 with switch ON. See Fig 1. If continuity does not exist, replace ECU. If continuity is as specified, check wiring circuit. See WIRING DIAGRAMS .
