TERMINALS OF ECU
1. CHECK POWER STEERING ECU
HINT:
As connector z8 uses a lock lever, each terminal cannot be checked while the connector is still connected to the power steering ECU.

Terminal Description |
---|---|---|
z8-1 (V) |
W |
V phase motor output |
z8-2 (U) |

(a) Measure the voltage and resistance according to the value(s) in the table below.
NOTICE:
When the P/S warning light is illuminated during a malfunction, the fail-safe function may cause the voltage of the power steering ECU terminals to become 0 V.
