SERIES 60 EGR TECHNICIAN'S GUIDE
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 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.Table 9-2 and see Figure 9-1.
[a]
If the coil resistance is to low replace the actuator assembly.
[b]
If the coil resistance is okay, 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
, try a test ECU or contact Detroit Diesel
Technical Service.
