FLASH CODE:
62
DDR DISPLAY:
(AUXILIARY OUTPUT #8) OPEN CIRCUIT
SAE J1587 CODE:
SID: 056 FMI: 4
Indicates that the function assigned to the Auxiliary Output #1 circuit input is open or is shorted to ground. This
diagnostic condition is detected when the Auxiliary Output #8 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 #8.
FLASH CODE:
63
DDR DISPLAY:
PWM DRIVER #1 SHORT TO BATTERY (+)
SAE J1587 CODE:
SID: 057 FMI: 3
Indicates that the PWM DRIVER #1 circuit output is shorted to battery (+). This diagnostic condition is detected
when the DDEC III ECM is unsuccessful In turning ON the circuit function.
NOTE:
The DDEC III ECM supplies a switched ground to the PWM DRIVER #1 circuit to
turn ON the circuit function.
FLASH CODE:
63
DDR DISPLAY:
PWM DRIVER #1 OPEN CIRCUIT
SAE J1587 CODE:
SID: 057 FMI: 4
Indicates that the PWM DRIVER #1 circuit output is open or is shorted to ground. This diagnostic condition is
detected when the PWM Driver #1 function is OFF and the DDEC III ECM measures a low voltage on the circuit
output.
FLASH CODE:
63
DDR DISPLAY:
PWM DRIVER #2 SHORT TO BATTERY (+)
SAE J1587 CODE:
SID: 058 FMI: 3
Indicates that the PWM DRIVER #2 circuit output is shorted to battery (+). This diagnostic condition is detected
when the DDEC III ECM is unsuccessful in turning ON the circuit function.
NOTE:
The DDEC Ill ECM supplies a switched ground to the PWM DRIVER #2 circuit to
turn ON the circuit function.
FLASH CODE:
63
DDR DISPLAY:
PWM DRIVER #2 OPEN CIRCUIT
SAE J1587 CODE:
SID: 058 FMI: 4
Indicates that the PWM DRIVER #2 circuit output is open or is shorted to ground. This diagnostic condition is
detected when the PWM Driver #2 function is OFF and the DDEC III ECM measures a low voltage on the circuit
output.
FLASH CODE:
63
DDR DISPLAY:
PWM DRIVER #3 SHORT TO BATTERY (+)
SAE J1587 CODE:
SID: 059 FMI: 3
Indicates that the PWM DRIVER #3 circuit output is shorted to battery (+). This diagnostic condition is detected
when the DDEC III ECM is unsuccessful in turning ON the circuit function.
NOTE:
The DDEC III ECM supplies a switched ground to the PWM DRIVER #3 circuit to
turn ON the circuit function.
