3. Bus check (without PAST): Check the bus check (without PAST) of units indicating "U1000" or "U1001" on DTC check. Draw a line on the
diagnosis sheet to indicate the possible error circuit.
NOTE:
-
While an error occurred in the past according to DTC check, it is unclear which signal is not received. Assume that errors were detected from all
reception items.
-
Draw a single line among the unit and all reception items. (Work flow differs from Bus check (with PAST).)
a. Reception item of "EPS": Assume that the unit could not receive the signals from ECM, ABS, and M&A. Draw a line among EPS, ECM,
ABS, and M&A (line 3-a in the figure below).
b. Reception item of "ABS": Assume that the unit could not receive the signal from ECM. Draw a line between ABS and ECM (line 3-b in the
figure below).
