(1) Erase the diagnosis code.
(2) Turn on the corresponding lamp.
(3) Check the diagnosis code No.B1E1D is set.
Is the diagnosis code set?
Go to Step 5.
The trouble can be an intermittent malfunction (GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 5. Check whether the diagnosis code is set again.
