Section 62.2
Troubleshooting Flash Code 63, SID 57–60/FMI 0/1/3/4/7

The following procedures will troubleshoot Flash Code 63.‪

Section 62.2.1
Determine Assignment

Perform the following steps to determine assignment.‪

  1. Turn ignition ON and plug in the diagnostic tool.
  2. Select INs/OUTs. To what is PWM assigned? Write down assignment vs cavity and code, listed in Table "PWM Assignments" .

    Table 1. PWM Assignments
  3. Select code display.
  4. Determine Failure Mode Identifier (FMI).
    1. If FMI 3 displays, there is a short to the battery. Refer to "62.2.2 Verify Short to Battery" .
    2. If FMI 4 displays, refer to step 5 .
    3. If the FMI is 0, 1, or 7, call the Detroit Diesel Customer Support Center (313–592–5800).
  5. Determine if there is a component wired to this position to verify function.
    1. If there is a component wired to this position, refer to "62.2.3 Check Component Connections" .
    2. If there is no component wired to this position, reprogram to eliminate the assigned function. (A change may be required to the DDC mainframe.) Refer to "62.2.4.1 Verify Repairs" .

Section 62.2.2
Verify Short to Battery

Perform the following steps to verify a short to battery:‪

  1. Turn ignition OFF.
  2. Disconnect the vehicle connector: if PWM 1 or 2; engine connector if PWM 3, 4, 5 or 6.
  3. Measure voltage between the cavity with the code and the good ground.
    1. If the voltage measurement is greater than 3 volts, the connector is shorted to the battery. Repair. Refer to "62.2.4.1 Verify Repairs" .
    2. If the voltage measurement is less than 3 volts, contact the Detroit Diesel Customer Support Center (313–592–5800).

Section 62.2.3
Check Component Connections

Perform the following steps to check component connections:‪

  1. Turn the vehicle ignition switch to the OFF position.
  2. Inspect the connections of the PWM wire associated with the flash code logged at both harness connector and the item being driven.
    1. If the connectors are damaged or broken, repair or replace the damaged terminals. Verify repairs. Refer to "62.2.4.1 Verify Repairs" .
    2. If the connectors are not damaged or broken, ensure the item is connected to the pulse width modulation wire. If the item is not connected, repair or replace the connector. Verify repairs. Refer to "62.2.4.1 Verify Repairs" .
    3. If the item is connected, measure the resistance. Refer to "62.2.4 Measure Resistance Between Connector and the ECM/ECU Case" .

Section 62.2.4
Measure Resistance Between Connector and the ECM/ECU Case

Perform the following steps to measure resistance between the connector and the ECM/ECU case:‪

  1. Turn the vehicle ignition to the OFF position.
  2. Ensure connector is installed on the engine harness side or vehicle harness side.
  3. Disconnect the PWM wire associated with the code logged at the component.
  4. Measure the resistance between the removed connector and the ECM/ECU case.
    1. If the resistance measurement is les than 100K Ω, verify the pin assignment with wiring - view with diagnostic tool. Refer to "62.2.4.1 Verify Repairs" .
    2. If the resistance measurement is greater than 100,000 Ω, the wire is open or shorted to battery. Repair or replace the wire. Verify repairs. Refer to "62.2.4.1 Verify Repairs" .
Section 62.2.4.1
Verify Repairs

Perform the following steps to verify repairs for Flash Code 63.‪

  1. Reconnect all connectors and clear all codes from the diagnostic tool.
  2. Plug in the diagnostic tool.
  3. Turn vehicle ignition switch to the ON position.
    1. If Flash Code 63 was not logged, no further troubleshooting is required.
    2. If Flash Code 63 was logged, please review this section from the first step to find the error. Refer to "62.2.1 Determine Assignment" .
