When the suppressor fails it normally back feeds power to the ecm and burns it out to the point that it needs to be replaced . The same is true for the ICV on the fuel pump. And in some cases the engine harness must be replaced. If you have a test ecm you can install it would be helpful to try in troubleshooting. If not you will need to seek a repair shop.

CODE

Fault Code: 539
PID: P018
SPN: 633
FMI: 11
LAMP: Yellow

Open circuit detected at the transient suppressor in the injection control valve circuit in the engine harness.

Possible white smoke and rough running.

The transient suppressor absorbs the extra current created when the injection control valve closes after an injection event. Without the transient suppressor working properly, high voltage would be transmitted back into the ECM and damage the pump driver circuits.

The transient suppressor extends from the trunk of the engine harness and is mounted with a p-clip to the engine block. It is a small copper colored cylinder with a red and a black wire extending from one end. It is located just below where the injection lines connect to the fuel pump behind the fuel filter. The injection control valve is located at the rear of the fuel injection pump, on the top of the distributor, and below the accumulator.
