INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe hand−held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or rich, and other data
from the time the malfunction occurred.
1CHECK FUSE(THROTTLE FUSE)
(a) Remove the THROTTLE fuse from the engine room R/B
No.1.
(b) Check for continuity in the THROTTLE fuse.
Standard: Continuity
(c) Reinstall the THROTTLE fuse.
NG CHECK FOR SHORT IN ALL HARNESSES AND
COMPONENTS CONNECTED TO FUSE
OK
2 INSPECT ECM(+BM VOLTAGE)
(a) Measure the voltage between the specified terminals of
the E10 and E11ECM connectors.

DTC P0617 STARTER RELAY CIRCUIT HIGH
CIRCUIT DESCRIPTION
While the engine is being cranked, the positive battery voltage is applied to terminal STA of the ECM.
If the vehicle is being driven and the ECM detects the starter control signal (STA), the ECM concludes that
the starter control circuit is malfunctioning. The ECM will turn on the CHK ENG and a DTC is set.

INSPECTION PROCEDURE
HINT:
S After completing repairs, confirm that P0380 is not present again.
S Read freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P0380)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs.
Result:
Display (DTC output)Proceed to
P0380A
P0380 and P0622B
HINT:
If any other codes besides P0380 and P0622 are output, perform troubleshooting for those DTCs first.
