Section 6.5 SID 58, FMI 4, Flash Code 63, PWM No. 2 Open Circuit

Section 6.5
SID 58, FMI 4, Flash Code 63, PWM No. 2 Open Circuit

The PWM No. 2 has an open circuit.‪

Section 6.5.1
Troubleshooting SID 58, FMI 4, Flash Code 63

Troubleshoot as follows:‪

NOTICE:

To avoid damage to the harness and connectors when disconnecting harness connectors, ensure the pulling force is applied to the connectors and not to the wires extending from the connectors.‪

  1. Check wire 909 (light green, PWM No. 2 out) for continuity at cavity Y-1 in the Engine Sensor Harness (ESH) 30–pin connector (see Figure "Engine Sensor Harness 30–pin Connector" ) and pin E in the throttle actuator connector (see Figure "Throttle Actuator Connector" ). If there is an open path, repair or replace the wire, pins, and sockets.

    1. If the code is still active, go to step 2.
    2. If the code is no longer active, refer to "6.5.2 Verification" .
  2. Check wire 909 (light green, PWN No. 2 out) for short to wire 956 (black, throttle actuator ground) at cavity Y-1 in the ESH 30–pin connector (see Figure "Engine Sensor Harness 30–pin Connector" ) and pins E (wire 909) and B (wire 956) in the throttle actuator connector (see Figure "Throttle Actuator Connector" ). If there is a short, repair or replace the wire(s), pins, and sockets.
    1. If the code is still active, go to step 3.
    2. If the code is no longer active, refer to "6.5.2 Verification" .
  3. Check wire 909 (light green, PWM No. 2 out) for short to wire 416 (gray, 5 VDC sensor supply) at cavities Y-1 (wire 909) and W-1 (wire 416) in the ESH 30–pin connector (see Figure "Engine Sensor Harness 30–pin Connector" ) and pins C (wire 416) and E (wire 909) in the throttle actuator connector (see Figure "Throttle Actuator Connector" ). If there is a short, repair or replace the wire(s), pins, and sockets.
    1. If the code is still active, call Detroit Diesel Technical Service.
    2. If the code is no longer active, refer to "6.5.2 Verification" .

Section 6.5.2
Verification

Verify that troubleshooting was successful:‪

  1. Check the DDR to see if SID 58, FMI 4, Flash Code 63 is still active.
    1. If the code is still active, go to step 2.
    2. If the code is not active, troubleshooting is complete.
  2. If code is still active, call Detroit Diesel Technical Service.
