TERMINALS OF ECU

1. CHECK POWER STEERING ECU




HINT: As connector "z6" uses a lock lever, each terminal cannot be checked while the connector is still connected to the power steering ECU.





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





If the result is not as specified, the ECU may have a malfunction.
