DIAGNOSTIC TROUBLE CODE PROCEDURES

CIRCUIT OPERATION

｠

The ECM (terminal No. 61) apply a battery positive
voltage  into  the  generator  FR  terminal  No.  4  via
resistance inside the unit.

TECHNICAL DESCRIPTION

｠

When  the  generator  field  coils  are  controlled,  the
generator FR terminal inputs signal to the ECM.

｠

The  ECM  detects  the  generator  output  with  the
input signal, and controls the idle air control motor
according to the generator output.

DTC SET CONDITIONS

Check Condition

｠

Engine speed is higher than 50 r/min.

Judgement Criterion

｠

Input  voltage  from  the  generator  FR  terminal  has
continued  to  be  approximately  battery  positive
voltage for 20 seconds.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set area: )

｠

Generator failed.

｠

Connector damage.

｠

Harness damage.

｠

ECM failed.
