Test mode should be deselected once the
test is complete.
Check diesel fuel tank.
Check diesel. Check diesel maximum
torque solenoid.
Check diesel stop solenoid 20DV.
Check diesel lube oil system.
Check diesel cooling water system.
Clear fault and reset 88CR.
Investigate starting motor circuits.
Checking starting motor module in PECC.
Check for proper operation of ratchet mech-
anism.
Check ratchet permissives.
Check ratchet motor overload (MCC).
Check for proper operation of ratchet mech-
anism.
Check ratchet system. Monitor vibration
when cooldown cycle is reinitiated.
Investigate problem with cooling water sys-
tem or main cooling water pump.
Check cooling water system for leaks.
