FLASH CODE:
32
DDR DISPLAY:
STOP ENGINE LIGHT SHORT TO BATTERY (+)
SAE J1587 CODE:
SID: 238 FMI: 3
Indicates that the Stop Engine Light (SEL) circuit is shorted to battery (+). This diagnostic condition is detected when
the DDEC III ECM is unsuccessful in turning ON the stop engine light. This diagnostic code is typically:
(1)
failed short SEL light bulb
(2)
SEL wire in vehicle harness is shorted to battery (+)
NOTE:
The DDEC III ECM supplies a switched ground to the stop engine light circuit to
turn ON the light.
FLASH CODE:
32
DDR DISPLAY:
STOP ENGINE LIGHT OPEN CIRCUIT
SAE J1587 CODE:
SID: 238 FMI: 4
Indicates that the Stop Engine Light (SEL) circuit is open or shorted to ground. This diagnostic condition is detected
when the stop engine light is OFF and the DDEC III ECM measures a low voltage on the stop engine light circuit
output. This diagnostic code is typically:
(1)
failed open SEL light bulb
(2)
SEL wire in vehicle harness is open or shorted to ground
FLASH CODE:
32
DDR DISPLAY:
CHECK ENGINE LIGHT SHORT TO BATTERY (+)
SAE J1587 CODE:
SID: 239 FMI: 3
Indicates that the Check Engine Light (CEL) circuit is shorted to battery (+). This diagnostic condition is detected
when the DDEC III ECM is unsuccessful in turning ON the stop engine light. This diagnostic code is typically:
(1)
failed short CEL light bulb
(2)
CEL wire in vehicle harness is shorted to battery (+)
NOTE:
The DDEC III ECM supplies a switched ground to the check engine light circuit to
turn ON the light.
FLASH CODE:
32
DDR DISPLAY:
CHECK ENGINE LIGHT OPEN CIRCUIT
SAE J1587 CODE:
SID: 239 FMI: 4
Indicates that the Check Engine Light (CEL) circuit is open or shorted to ground. This diagnostic condition is
detected when the check engine light is OFF and the DDEC III ECM measures a low voltage on the check engine
light circuit output. This diagnostic code is typically:
(1)
failed open CEL light bulb
(2)
CEL wire in vehicle harness is open or shorted to ground
FLASH CODE:
33
DDR DISPLAY:
TURBO BOOST SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 102 FMI: 3
Indicates that the engine Turbo Boost Sensor (TBS) input to the ECM has exceeded 85% (normally > 4.25 volts) of
the sensor supply voltage. This diagnostic condition is typically:
(1)
open sensor return circuit
(2)
sensor signal circuit is shorted to the sensor +5 volt supply
