| TERMINAL INSPECTION |
Disconnect the connector and measure the voltage or resistance according to the value(s) in the table below.
Text in Illustration *a Front view of wire harness connector
(to Skid Control ECU [Brake Actuator Assembly])- - - HINT:
- The voltage cannot be measured with the connector connected to the skid control ECU (brake actuator assembly) as the connector is watertight.
