Hazard Warning Switch -- Inspection

1. INSPECT HAZARD WARNING SIGNAL SWITCH ASSEMBLY (w/o Audio)

Inspect the hazard warning signal switch assembly.
1. Measure the resistance according to the value(s) in the table below.
  Standard Resistance:
  Tester Connection
  Switch Condition
  Specified Condition
  4 - 1
  Hazard warning switch off
  10 kΩ or higher
  Hazard warning switch on
  Below 1 Ω
  If the result is not as specified, replace the hazard warning signal switch assembly.
