Electronic Brake Control Module: Testing and Inspection

ECU TERMINAL MEASUREMENT

Using TOYOTA breakout-box and TOYOTA hand-held tester, measure the ECU terminal value.

(1) Hook up the TOYOTA hand-held tester and TOYOTA breakout-box to the vehicle.
(2) Read the ECU input/output values by following the prompts on the tester screen.

HINT:  TOYOTA hand-held tester has a "Snapshot" function. This records the measured values and is effective in the diagnosis of
intermittent problems.

Please refer to the TOYOTA hand-held tester/TOYOTA breakout-box operator's manual for further details.
