SYMPTOM/CONDITION
Subject model vehicles are equipped with an antidiesel relay that is designed to engage the air conditioning compressor for a period of 5 to 10 seconds
after the ignition switch is turned off. This puts a load on the engine and eliminates engine after-run (dieseling).
For complaints of dieseling on these vehicles, check the wiring connections at the relay to ensure they are proper (see illustrations). If necessary, correct
as follows:
FIGURE 1
REPAIR PROCEDURE
The anti-diesel relay is a gold colored relay located on the left shock tower on the front side (Figure 1). There are two insulators connected to the relay.
One is a black 2-way and the other is a red 3-way.

Disconnect the red 3-way from the relay.
