NG:  Go to step  4

OK: Go to next Step 

1. Replace the front door ECU LH with a new one or normally functioning one (see FRONT DOOR ).
2. Check that the entry function operates normally (See REMOVAL )

   OK: Operates normally 

NG: REPLACE CERTIFICATION ECU  (See REMOVAL )

OK: END (FRONT DOOR ECU LH IS DEFECTIVE) 

1. Measure the resistance according to the value (s) in the table below.

   Standard resistance
