SYMPTOM/CONDITION

A subject model vehicle fails a state "CO" emission idle inspection performed with transmission in park/neutral.

DIAGNOSIS/CORRECTION

If vehicle passes "CO" idle emissions test in drive gear, but fails in park/neutral, the logic module must be replaced with service module PN 5226870.

If vehicle still fails when tested in drive or after module is replaced, further diagnosis is required to find cause and correction.

INFORMATION

Service logic module PN 5226870 is calibrated identical to the original module, except the service module remains in closed loop fuel control in park/neutral. The original module allowed open loop fuel control in park/neutral, which in some cases causes excessive "CO" in state idle emission testing.

POLICY: Reimbursable within the provisions of the warranty

TIME ALLOWANCE: Refer to existing Labor Operation Time Schedule for logic module replacement.

FAILURE CODE: OX - Wrong Part
