Check Procedure 12-- High mount stop lamp
Please refer to Chapter 1 “Protection for Electrical Safety”.
Turn the key switch to ON, check the high mount stop lamp connector on main
cable with a multimeter set at 200V DC (connect the red probe+ to green/yellow wire and connect the
black probe - to black wire) while depressing the brake pedal. The voltage should be 12V. Perform the
following checks if the voltage is 0V:
1. Check whether the DC converter outputs a 12V voltage. Check the converter if the output is 0V and
replace it if necessary. Continue with Step 2 if it is ok.
2. Check the fuse in the fuse box and replace it if necessary. If the fuse is ok, go to Step 3.
3. Check the brake switch for normal operation.
4. If everything is ok and the measured voltage is still 0V, replace the main cable.
Check Procedure 13 - wiper
Please refer to Chapter 1 “Protection for Electrical Safety”.
Turn the key switch to ON, check the wire connected to the wiper of main cable
with a multimeter set at 200V DC (connect the red probe + to yellow/blue wire and connect the black probe -
to black wire). The voltage should be 12V. Perform the following checks if the voltage is 0:
2. Check the fuse in the fuse box and replace it if necessary. If the fuse is ok, go to Step 3.
3. If no problem is found in the above Step 1 and 2 and there is no 12V output, replace the wiper
harness.
4. If the above checks are well(ie. there is a 12V output), connect the wiper interface to the
main cable and turn on the wiper switch to check the wiper for normal operation, replace the wiper if
it does not operate.
1. Check whether the DC converter outputs a 12V voltage. Check the converter if the output is 0V and
replace it if necessary. Continue with Step 2 if it is ok.
