E. ENG5V=ENGINE HARNESS +5 VOLT SUPPLY
NOTE This chart is only to be used if:
1) All basic mechanical checks and physical inspections have been performed with no problem found, and
2) Diagnosis of DDEC-11 was started at step Start-1 (page 3-121) and you have now been referred here.
ENG5V-1 Check for Low
l Was there also a Code 46?
ENG5V-2 Check for +5 Volts
l Turn ignition off.
l Disconnect the Oil Pressure Sensor
(OFS) and Turbo Boost Sensor
l Turn ignition on.
l Ateach sensor harness connector,
read voltage between socket C
and socket A.
ENG5V=3 Check ECM
l Check terminals at the ECM engine
harness connector (both the ECM
and harness side) for damaged,
bent, corroded and unseated pins
WHAT TO DO NEXT
-Go to 46-I, page 3-301.
*Go to ENG5V-2.
-Voltage reading is correct. Check
and 5.2 volts
voltage at next connector. If all
connector voltage readings are
correct, go to ENG5V-3.
*Go to ENG5V-6.
at all connectors.
connectors are okay.
Then go to ENG5V-30.
- Repair terminals/connectors,
page 3-2. Then go to ENG5V-30.
