DETAILED FLOW 

NOTE: To ensure a complete and thorough diagnosis, the battery, stater and generator test segments must be done as a set from start to finish.

1. PRELIMINARY INSPECTION 
   1. Perform the preliminary inspection. Refer to Diagnosis Procedure .

   >>

   GO TO 2.

2. STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM 
   1. Stop the operation of the power generation voltage variable control in either of the following procedures. CONSULT
      • After selecting "ENGINE", set the DUTY value of "ALTERNATOR DUTY" to 0 % by selecting "ALTERNATOR DUTY" of "Active Test". Continue "Active Test" until the end of inspection. (When the DUTY value is 0 or 100 %, the normal power generation is performed according to the characteristic of the IC regulator of the generator.)
      • Ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550-P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connector and erase the self diagnosis results history of the engine using CONSULT.]
