Toyota 84332-AE010 Switch Assy, Hazard Warning Signal

To check the hazard warning switch, it must first be removed from the center dashboard trim bezel, followed by testing for continuity between the terminals; if it fails, replacement is necessary. For replacement, carefully pry the upper cluster finish panel from the dashboard, then pull the panel out to disconnect the electrical connector at the rear of the switch, ensuring to squeeze the clips retaining the hazard switch. The power mirror control switch, located at the left end of the instrument panel, should be removed for testing continuity between its terminals; if continuity is not as specified, it should be replaced. To replace it, carefully pry the switch from the panel using tape on the screwdriver tip to avoid scratches, disconnect the electrical connector, and reinstall by reversing the removal procedure. The traction control switch, which works with the ABS braking system, should be removed for testing; continuity should be present when pressed and absent when released, with replacement required if it does not meet these conditions. For replacement, pry the switch from the panel, disconnect the electrical connector, and reinstall by reversing the removal procedure. The instrument panel light control switch, a rheostat controlling voltage to the lights, requires removal for testing; apply battery voltage to terminal 1 and a ground jumper to terminal 3, checking for varying voltage as the knob is turned. For replacement, on models with the rheostat below the left vent, pry the switch panel out of the dashboard with a screwdriver, ensuring to tape the tip to prevent scratches, while models with a thumb-wheel require the instrument cluster to be removed for access.
