Diagnosing Flash Code 13; Egr Valve Electric Current Is Too High; Egr Valve Coil Wiring - Detroit Diesel Series 60 EGR Technician Manual

LOGIC CODES (MECHANICAL FAILURES)
Logic codes indicate the detection of mechanical failures by the DDEC V system. The response
will be a Flash Code.

Diagnosing Flash Code 13

Failure Mode: SID 146, FMI 6
Indicates: EGR valve electric current is too high.
Response: Perform the following steps if the EGR valve current is too high.
1. Check for a short circuit.
2. Disconnect the harness connector from the actuator control valve coil.
3. Measure the coil resistance between pins A and B. See Figure 9-1 for pin locations and
compare the measured ohm values to the ohm values listed in Table 9-29–2.
[a] If the coil resistance is too low replace the actuator assembly.
[b] If the coil resistance is acceptable, go to step 4.
4. Disconnect engine harness at ECU and at coil and measure resistance across the two
pin connector pins.
[a] If resistance is less than 100 , the two wires are shorted to each other.
[b] If the resistance is greater than 100
