Component Testing

Static Test

  1. Ignition OFF, disconnect the harness connector at the S27 Head-Up Display Switch.
  2. Turn the dimming switch to minimum position.
  3. Test for 25-40 Ω between the signal terminal 3 and the low reference circuit terminal 1. Turn the dimming switch from minimum to maximum and verify the resistance increases in each position to 875-950 Ω in maximum position.
    • If the resistance does not change, replace the S27 Head-Up Display Switch.
