TROUBLESHOOTING CHARTS
FLASH CODE:
61
DDR DISPLAY:
XXX INJECTOR RESPONSE TIME LONG
SAE J1587 CODE:
SID: XX FMI: 0
Indicates that the time it takes from when the DDEC III ECM requests an injector be turned on to when the injector
solenoid valve actually closes is longer than the high limit of the expected range. This diagnostic condition is
typically:
(1)
bad injector harness/connection (high resistance)
(2)
blown fuses in the ECM battery (+) voltage supply harness
(3)
sticky solenoid valve
NOTE:
The injector diagnostic SID (Subsystem Identifier) indicates which cylinder number
has an injector with a long response time. The injector number describes the
cylinder and/or bank which has the injector with a long response time. The DDR
will display the injector text description in the table DDEC III Injector Numbering on
page 3-345.366.
Injector response times generally increase with low battery supply voltage and
decrease with high battery supply voltage. Although injector response times vary
from injector to injector at a given RPM, each individual injector response time
should remain relatively consistent from one firing to the next. Wide variations in
response time (typically +/- 0.2 msec) for one injector at a steady engine RPM may
indicate an electrical problem (faulty alternator or voltage regulator, poor or broken
ground cables, etc.).
FLASH CODE:
62
DDR DISPLAY:
(AUXILIARY OUTPUT #1) SHORT TO BATTERY (+)
SAE J1587 CODE:
SID: 026 FMI: 3
Indicates that the function assigned to the Auxiliary Output #1 circuit output is shorted to battery (+). This diagnostic
condition is detected when the DDEC III ECM is unsuccessful in turning ON the configurable function.
NOTE:
The DDR will display the parameter text description in TABLE 2 (ECM Output
Options) to identify the function assigned to AUXILIARY OUTPUT #1.
The DDEC III ECM supplies a switched ground to the AUXILIARY OUTPUT #1
circuit to turn ON the function assigned.
FLASH CODE:
62
DDR DISPLAY:
(AUXILIARY OUTPUT #1) OPEN CIRCUIT
SAE J1587 CODE:
SID: 026 FMI: 4
Indicates that the function assigned to the Auxiliary Output #1 circuit output is open or is shorted to ground. This
diagnostic condition is detected when the Auxiliary Output #1 function is OFF and the DDEC III ECM measures a low
voltage on the circuit output.
NOTE:
The DDR will display the parameter text description in TABLE 2 (ECM Output
Options) to identify the function assigned to AUXILIARY OUTPUT #1.
