CHECK AT ABS-ECU TERMINAL
TERMINAL VOLTAGE TABLE
NOTE
There are two ECUs with the same shape inside the floor
console, o n e above the other. The upper ECU is the ABS-ECU
and has a blue connector. The lower ECU is the transfer-ECU
and has a green connector.
(1) Measure the voltages between the respective terminal
and earth.
(2) The terminal layout is shown in the illustration.
