turning the power switch off, waiting time may be required before
disconnecting the cable from the negative (-) auxiliary battery
terminal. Therefore, make sure to read the disconnecting the cable from
the negative (-) auxiliary battery terminal notices before proceeding
with work. Click here PROCEDURE 1. CHECK HYBRID VEHICLE CONTROL ECU (+B1, +B2 VOLTAGE) (a) Turn the power switch on (IG). (b) Measure the voltage according to the value(s) in the table below.
