3406B PEEC Truck Engines Equipped With Shutdown System
Reports indicate a problem servicing and programming a 3406B (PEEC) Truck Engine equipped with a Kysor ® Engine Shutdown System. The Kysor® Engine Shutdown disconnects the Programmable Electronic Engine Control (PEEC) voltage supply when the engine is without oil pressure for a specified amount of time (approximately 30 seconds). This results in an inability to program and service the PEEC system.
Servicing and programming the PEEC can be accomplished by supplying power directly to the PEEC. This can be done as follows.
1. Remove the "A" wire from the J2 connector with a Deutsch pin remover (part to the 1U5803 Deutsch Connector Repair Kit).
2. Attach a 8T8729 Pin to a 16 AWG jumper wire and insert the pin into "A" position of the J2 connector.
3. Connect the other end of the jumper wire to a battery positive (+) source.
4. Connect power to the Throttle Position Sensor and the Vehicle Speed Buffer. In most cases (dependent on OEM wiring) this can be done by connecting a jumper wire from a battery positive (+) source to "A" wire removed in Step 1. An 8T8730 Socket can be used to connect the jumper wire to the 8T8729 Pin on the end of wire "A".
NOTE: Be sure to keep all contacts isolated from any grounded surface.
When power is supplied to all units of the PEEC system, normal servicing and programming capabilities are restored. When servicing and programming are complete, remove the jumpers and install wire "A" in position "A" in the J2 connector. Be sure the 8T8729 Pin is fully installed in the connector. The pin must withstand a pull of 10 pounds and still remain in place in the connector body.
