Measure the resistance of harness between starter relay and starter motor.
Connector & terminal
LHD model
(B225) No. 10 — (B14) No. 1:
RHD model
(B225) No. 25 — (B14) No. 1:
Is the resistance less than 1 Ω?
Check the ECM voltage supply and ground line.
Repair the harness and connector.
NOTE:
In this case, repair the following item:
• Open circuit of harness between starter relay and starter motor
• Poor contact of joint connector (RHD model)
