612
Invalid Interrupt
Several different things can happen within the microprocessor that
will cause this fault. The EPM will reset itself in the event this fault is
set, and the MIL will be on until the code is cleared. This fault should
be erased after diagnosis by removing battery power. It will not self-
erase.
During this active fault, Power Derate (level 2) will be enforced. When
this is enforced, maximum throttle position will be 20%. This is
enforced until the fault is manually cleared.
613
A/D Loss
This fault should be erased after diagnosis by removing battery
power. It will not self-erase.
During this active fault, Power Derate (level 2) will be enforced. When
this is enforced, maximum throttle position will be 20%. This is
enforced until the fault is manually cleared.
614
RTI 1 Loss
Several different things can happen within the microprocessor that
will cause this fault. The EPM will reset itself in the event this fault is
set, and the MIL will be on until the code is cleared. This fault should
be erased after diagnosis by removing battery power. It will not self-
erase.
During this active fault, Power Derate (level 2) will be enforced. When
this is enforced, maximum throttle position will be 20%. This is
enforced until the fault is manually cleared.
615
Flash Checksum Invalid
Several different things can happen within the microprocessor that
will cause this fault. The EPM will reset itself in the event this fault is
set, and the MIL will be on until the code is cleared. This fault should
be erased after diagnosis by removing battery power. It will not self-
erase.
During this active fault, Power Derate (level 2) will be enforced. When
this is enforced, maximum throttle position will be 20%. This is
enforced until the fault is manually cleared.
616
RAM failure
This fault will set if the EPM detects a problem accessing or writing
information to RAM. This fault will not self erase and must be cleared
manually.
631
External 5V Ref Lower Than Expected
This fault will set if the 5 Volt reference is below 4.6 volts.
632
External 5V Ref Higher Than Expected
This fault will set if the 5 Volt reference is above 5.4 volts.
655
RTI 2 Loss
Several different things can happen within the microprocessor that
will cause this fault. The EPM will reset itself in the event this fault is
set, and the MIL will be on until the code is cleared. This fault should
be erased after diagnosis by removing battery power. It will not self-
erase.
During this active fault, Power Derate (level 2) will be enforced. When
this is enforced, maximum throttle position will be 20%. This is
enforced until the fault is manually cleared.
656
RTI 3 loss
Several different things can happen within the microprocessor that
will cause this fault. The EPM will reset itself in the event this fault is
set, and the MIL will be on until the code is cleared. This fault should
be erased after diagnosis by removing battery power. It will not self-
erase.
During this active fault, Power Derate (level 2) will be enforced. When
this is enforced, maximum throttle position will be 20%. This is
enforced until the fault is manually cleared.
