Fault Condition: This fault can only be detected if the engine brake is demanded ON. If the fault clears, the compression brake system will not be enabled until the power is cycled.The engine brake must be operated to ensure the fault has been cleared. The engine brake can only be operated with the engine oil temperature above 131ºF (55ºC), the vehicle moving and the engine speed above 1200rpm. FMI 3 indicates there is a short circuit to voltage in the Engine Compression Brake Solenoid control circuit. Possible repairs: Turn the ignition key OFF first. 1) If code PPID 122 is...

The engine brake can only be operated with the engine oil temperature above 131ºF (55ºC), the vehicle moving and the engine speed above 1200rpm. FMI 5 indicates there is an open circuit in the Engine Compression Brake Solenoid circuit. Possible repairs: Turn the ignition key OFF first. 1) If code PPID 122 is not set, wiggle...

Fault Condition: PPID 35 will set with FMI 3 if the EGR ECU detects a short circuit to voltage in the exhaust gas temperature probe circuit. Possible repairs: Turn the ignition key OFF first. 1)If the FMI is 3 (voltage high/open) or 5 (current low/open), replace the EGR Mass Flow Sensor assembly and retest the system.2)Remove connector A from the EGR ECU. Turn the ignition switch ON. Check for battery voltage (+12V) between pin 2 of EGR ECU connector A and a known good ground. If battery voltage is NOT present, a problem exists between EGR ECU connector A pin...

Fault Condition: PPID 35 will set with FMI 4 if the EGR ECU detects a short circuit to ground in the exhaust gas temperature probe circuit. Possible repairs: Turn the ignition key OFF first. 1) If the FMI is 4 (voltage low), inspect the harness that connects the heater probe to the EGR ECU for any areas where the insulation has worn through and is touching ground. Repair the short to ground orreplace the EGR Mass Flow Sensor assembly.2) Remove connector A from the EGR ECU. Turn the ignition switch ON. Check for battery voltage (+12V) between pin 2 of...
