WARNING: This page is about a different car, the 2004 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.

LIGHT CONTROL RHEOSTAT

Inspect continuity.

Check the continuity between the light control rheostat connector terminals when operating the rheostat volume knob.

Table Standard:

CONTINUITY

Switch	Terminal No. (Symbol)	Continuity
Turn the knob to maximum	1(TC)<=>3(T)	Continuity
Other conditions of the above	1(TC)<=>3(T)	No continuity

Fig 1: Checking Continuity

Check resistance.
1. Check the resistance between terminal 4 (RV) and terminal 3 (T) when operating the light control rheostat volume knob. Also, check that the resistance changes continuously.
Standard resistance:

Turn the knob to maximum: Approx. 10 kΩ

Turn the knob to minimum: Approx. 0 kΩ
