Make: Detroit
Engine: DD15 GHG17 (2017 & Newer)
PID: N/A
SPN: 3696
FMI: 4
Description: Diesel Particulate Filter Regeneration Switch Short Circuit to Ground
Troubleshooting:
DESCRIPTION:
DPF regeneration switch is shorted to ground.
MONITORED PARAMETER:
4/17 Regen switch.
TYPICAL ENABLING CONDITIONS:
Key on, engine off.
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
VERIFICATION:
Cycle the key to power down, then cycle the key back on.
POSSIBLE CAUSES:
1. Faulty wiring.
2. Common Powertrain Controller (CPC) needs reprogramming.
3. CPC needs proper configuration.
3. Faulty CPC.

PID: N/A
SPN: 3695
FMI: 9
Description: DPF Regen Inhibit MUX Switch Message Stopped Arriving
Troubleshooting:
DESCRIPTION:
This fault code sets when the common powertrain controller (CPC) does not see the diesel
particulate filter (DPF) inhibit switch over J-1939 CAN.
MONITORED PARAMETER:
Diesel Particulate Filter (DPF) inhibit switch.
TYPICAL ENABLING CONDITIONS:
Key on, engine off.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
None
VERIFICATION:
Cycle the key to power down, then cycle the key back on.
NOTE: This fault code only sets when the CPC is parameterized to receive the diesel
particulate filter (DPF) inhibit switch from another module over the J1939 CAN.
POSSIBLE CAUSES:
1. CPC needs reprogramming.
2. Faulty CPC.
