DTC P2300 (24), P2301 (24), P2303 (25), P2304
(25)

GENERAL

Front (Code 24) and Rear (Code 25) Ignition
Coils
A combination of these codes will set if the ignition coil rise
time is out of range. This could occur if there is an open ignition
coil or loss of power to the ignition coil. If multiple codes are
set, P2303 (25), P2304 (25) the cause may be an ignition coil
power failure.
See Figure 2-113. The ignition coil receives power from the
ignition relay at ignition coil pin B (3) at the same time that the
fuel pump and fuel injectors are activated.

DIAGNOSTICS
PART NUMBER
B-48115 BREAKOUT BOX
HD-34730-2C FUEL INJECTOR TEST LAMP
HD-41404-B HARNESS CONNECTOR TEST KIT
HD-44687 IGNITION COIL CIRCUIT TEST
ADAPTER
Diagnostic Notes
Each reference number below correlates to a circled number
on the flow chart(s).
1. Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404-B), purple pin probes and patch cord.
2. Connect BREAKOUT BOX (Part No. B-48115)to ECM.
See 2.6 BREAKOUT BOX.
3. Plug IGNITION COIL CIRCUIT TEST ADAPTER (Part
No. HD-44687) and FUEL INJECTOR TEST LAMP (Part
No. HD-34730-2C) into Breakout Box. Note that cranking
the engine with test lamp in place of the ignition coil can
sometimes cause P2300 (24), P2301 (24), P2303 (25),
P2304 (25). This condition is normal and does not by itself
indicate a malfunction. Codes must be cleared if this con-
dition occurs.
4. If resistance greater than 1 ohm is found between ECM
connector [10] terminal "25" OR "34" and terminal "9", but
not both, the open must be repaired but this repair will not
correct the concern. If resistance greater than 1 ohm is
found between ECM connector [10] terminal "31" OR "32"
and terminal "9", but not both, the open must be repaired
but this repair will not correct the concern.
