STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM

Stop the operation of the power generation voltage variable control in either of the following procedures.

• After selecting “ENGINE” of “SELECT SYSTEM” using CONSULT, 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 voltage regulator of the alternator.)

• Turn the 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 connec-

tor and erase the self-diagnosis results history of the engine using CONSULT.]

>> GO TO 3.

3.

DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI

Perform the charging system test using Multitasking battery and electrical diagnostic station GR8-1200 NI or

Battery and electrical diagnostic analyzer EXP-800 NI. Refer to the applicable Instruction Manual for proper

testing procedures.
Test result

NO PROBLEMS>>Charging system is normal and will also show “DIODE RIPPLE” test result.

NO VOLTAGE>>GO TO 4.

LOW VOLTAGE>>GO TO 12.

HIGH VOLTAGE>>GO TO 14.

EXCESSIVE RIPPLE, OPEN PHASE, OPEN DIODE or SHORTED DIODE>>Replace  the  alternator.  Per-

form “DIODE RIPPLE” test again using Multitasking battery and electrical diagnostic station GR8-

1200 NI or Battery and electrical diagnostic analyzer EXP-800 NI to confirm repair.
