CIRCUIT DESCRIPTION

DTC Detecting Condition:

ECM controls idle speed to the most appropriate speed according to a signal from the power steering pressure sensor.

Wiring Diagram:

Step 1 - 2:

INSPECTION PROCEDURE

CHECK FOR INTERMITTENT PROBLEMS

Hand-held tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the ECM is in check mode with hand-held tester. In check mode, the ECM uses 1 trip detection logic, which has a higher sensitivity to malfunctions than normal mode (default), which uses 2 trip detection logic.

a. Clear the DTCs.
b. Set the check mode.
c. Perform a simulation test.
d. Check the connector and terminal.
e. Wiggle the harness and connector.
