Vpod Input Pressure Test; Vpod Part Number And Supply Voltage Test And Part Number Check - Detroit Diesel Series 60 EGR Technician Manual

VPOD Input Pressure Test

Perform the following steps to test the VPOD input pressure.
1. Measure the VPOD input pressure to Port 1.
[a] If the supply pressure is not between 703-1296 kPa (90-120 psi), troubleshoot the
vehicle air system until that result is obtained. Repair as necessary.
[b] If the supply pressure is between 703-1296 kPa (90-120 psi), perform a
VPOD Part Number and Supply Voltage Test.
2. Verify repairs.

VPOD Part Number and Supply Voltage Test and Part Number Check

Perform the follow steps to verify the VPOD part number and supply voltage.
1. Check VPOD label to determine if it is + 12 V or + 24 V system.
NOTE:
A 1,000 resistor or a volt Ohm meter is required to perform step 2.
2. Unplug the VPOD wire connectors and insert the 1,000
[a] Turn ignition switch ON.
[b] Measure voltage from pin 3 to pin 1.
[c] Plug in DDDL or DDR to measure the ECU voltage.
3. Is the VPOD part number and voltage and the ECU voltage correct?
[a] If the VPOD part number and voltage and the ECU voltage are correct, perform a
VPOD Wiring Test.
[b] If the VPOD part number and voltage and the ECU voltage were not correct, match
the VPOD component to the ECU voltage and perform a VPOD Wiring Test.
