Possible causes
and standard
value in normal
state
Cause Standard value in normal state/Remarks on troubleshooting
1 Defective fuse No. 3 If fuse is broken, circuit probably has ground fault (See cause 4).
2
Defective personal code
relay (Internal disconnection
or short circuit)
a Prepare with starting switch OFF, then carry out troubleshoot-
ing without turning starting switch ON. (Troubleshooting for
relay unit)
R07 (male) Resistance
Between (1) – (2) (300 – 600 z)
a Prepare with starting switch OFF, then turn starting switch ON
and carry out troubleshooting. (Troubleshooting by replace-
ment)
Replace personal code relay (R07) with another relay and perform
reproducing operation. If "E" of failure code goes off at this time,
replaced relay is defective.
