If the seat belt warning light illuminate, replace the ETACS-ECU.
The seat belt warning light should work normally.
STEP 3. Check the seat belt warning light bulb.
If the seat belt warning light bulb has blown, replace it.
The seat belt warning light should work normally.
If the seat belt warning light bulb is in good condition, go to Step 4.
STEP 4. Check the combination meter (printed-circuit board).
1. Remove the combination meter.
2. Remove the seat belt warning light bulb. Then measure the resistance between the bulb terminals.
3. Install the bulb to the combination meter, and then measure the resistance between connector C-29 terminals 29 and 34. The resistance reading at
this time should be much the same as the resistance measured at Step (2).
If the two resistance values are extremely different each other, repair or replace the combination meter (printed circuit board).
The seat belt warning light should work normally.
If the two resistance values are much the same, go to Step 5.
STEP 5. Check the combination meter connector C-29 and ETACS-ECU connector C-82 for damage.
