Non-Functioning of the AntiDiesel Relay Due to Miswiring of the Engine Harness Connector
April 18, 1983
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
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.
