Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical

circuits, a direct short may result. Damage to equipment, injury or death to personnel may occur.

INJECTOR RESPONSE TIME TEST

(1) Connect DDR to DDL connector

MC13.

(2) Start engine, (TM 9-2320-364-10).

(3) Select mode 10 to display fuel injector

response times on DDR.

(4) Compare response times of all eight

injectors.

(a) If any injector response time is

less than others or .80

milliseconds, perform Step (5)

below and replace injector,

(Para 4-2).

(b) If injector response times are

same as others or greater

than .80 milliseconds, response

times are OK.

(5) Turn OFF ENGINE switch.

DDR CYLINDER CUT OUT TEST

(1) Start engine, (TM 9-2320-364-10).

(2) Select mode 11 to display pulse

widths on DDR.

(3) Compare pulse widths of all eight

injectors.

(a) If pulse widths are less than the

NO CUT OUT PW (pulse widths),

or different from cylinder to

cylinder, perform Steps (4) and (5)

below and replace injector,

(Para 4-2).

(b) If pulse widths are equal to or

greater than the NO CUT OUT

PW (pulse widths), perform Step

(4) and (5) below and go to Step 8

of this Fault.

(4) Turn OFF ENGINE switch.

(5) Disconnect DDR from DDL connector

MC13.
