SYMPTOM PROCEDURES
INSPECTION PROCEDURE A-1: Communication with the M.U.T.-II/III is not possible.
CAUTION
Whenever the ECU is replaced, ensure that the
power supply circuit, the earthing circuit and the
communication circuit are normal.
COMMENTS ON TROUBLE SYMPTOM
It is suspected that the power supply circuit to the
ETACS-ECU is defective, or the wiring harness
between the diagnosis connector and the
ETACS-ECU or their connector(s) is damaged.
NOTE: If the wiring harness between the
ETACS-ECU and body earth is defective, also check
C-225 ETACS-ECU connector terminal No.3, and
repair if necessary.
