LVPS

Disconnect the LVPS cable from the engine

 

 

board. The voltage measures approximately +24

 

 

V dc between pin 1 (+24 V dc) and pin 2 (+24 V

 

 

dc ground). If incorrect, replace the LVPS.

 

 

 

2

Engine Board

Reconnect the LVPS cable and measure the

 

 

voltage on CN7-1. The reading should measure

 

 

approximately +24 V dc. If incorrect, disconnect

 

 

CN3, CN4, CN6, CN9, CN10 and CN11 from the

 

 

engine board. The voltage on CN7-1 measures

 

 

+24 V dc. If incorrect, replace the engine board.

 

 

If correct, reconnect one cable at a time check-

 

 

ing the voltage at CN7-1 until the FRU causing

 

 

the problem is found. Replace the failing FRU.

 

 

If the CN3 or CN9 are causing the problem, it is

 

 

necessary to disconnect each solenoid and

 

 

check the voltage at CN7-1. Replace the failing

 

 

FRU.
