Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT FUSE (STOP)
1. Remove the STOP fuse from the instrument panel junction block.
2. Measure the resistance of the fuse.
  Standard resistance:
  
  Below 1 Ω
NG: REPLACE FUSE

OK: Go to next step
INSPECT STOP LIGHT (REAR COMBINATION LIGHT)
1. Remove the rear combination light.
2. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 1, then check that the light comes oh.
  OK:
  
  Light comes on.
