INSPECTION
PROCEDURE
1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)
|
(a) Measure the resistance according to the value(s) in the table below. Text in Illustration
Standard Resistance:
If the result is not as specified, replace the air cleaner assembly. |
|
(b) Check the vacuum switching valve operation.
|
(1) When vacuum is applied to port E, check that air is sucked into the filter. Text in Illustration
If the result is not as specified, replace the air cleaner assembly. |

DESCRIPTION
The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunctions
detected by the ECM. By turning the ignition switch to ON, power is supplied to
the MIL circuit, and the ECM provides the circuit ground which illuminates the MIL.

CHECK FOR INTERMITTENT PROBLEMS
HINT:
Inspect the ECM using check mode. Intermittent problems are easier to detect
with the Techstream when the ECM is in check mode. In check mode, the ECM uses 1
trip detection logic, which is more sensitive to malfuncti ...
