On Board Diagnosis LogicEBS01F9Y
These self-diagnoses have the one trip detection logic.
MI will not light up for these diagnoses.
NOTE:
If DTC P0580 or P0581 is displayed with DTC P0606, first perform the trouble diagnosis for DTC P0605.
Refer to EC-1227, "
DTC P0605 ECM".
DTC Confirmation ProcedureEBS01F9Z
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Wait at least 10 seconds.
4. Press MAIN switch for at least 10 seconds, then release it and wait at least 10 seconds.
5. Press RESUME/ACCELERATE switch for at least 10 seconds, then release it and wait at least 10 sec-
onds.
6. Press SET COAST switch for at least 10 seconds, then release it and wait at least 10 seconds.
7. Press CANCEL switch for at least 10 seconds, then release it and wait at least 10 seconds.
8. If DTC is detected, go to EC-1223, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.
DTC No.Trouble Diagnosis
NameDTC Detecting Condition Possible Cause
P0580
0580ASCD steering switch
circuit low input

ECM detects that the ASCD steering switch is
stuck ON.
Harness or connectors
(The switch circuit is open or shorted.)

ASCD steering switch

ECM P0581
0581ASCD steering switch
circuit high input

An excessively high voltage signal from the
ASCD steering switch is sent to ECM.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

2. CHECK ASCD STEERING SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON.
2. Select “MAIN SW”, “RESUME/ACC SW”, “SET SW” and “CANCEL SW” in “DATA MONITOR” mode with
CONSULT-II.
3. Check each item indication under the following conditions.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between ECM terminal 102 and ground under the
following conditions.
OK or NG
OK >> GO TO 8.
NG >> GO TO 3.
3. CHECK ASCD STEERING SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ASCD steering switch (1) harness connector.
3. Disconnect ECM harness connector.
4. Check harness continuity between ASCD steering switch termi-
nal 2 and ECM terminal 103. Refer to Wiring Diagram.
5. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 5.
