and measure the resistance of the R/PK wire between pin 8 on A/C IMC
C1947 and BOB pin 46.
•
Is the resistance less than 5 ohms?
No =
REPAIR the R/PK wire.
F10 CHECK HIGH-VOLTAGE POWER TO A/C IMC
•
Disconnect the 12-volt auxiliary battery negative cable.
Yes =
REPLACE the A/C IMC.
•
Remove the high-voltage power distribution box (HVPDB) cover.
No =
GO to F11.
WARNING: The following test steps contain high-voltage
procedures. High-voltage insulated safety gloves and face shield must
be worn when performing the following steps. Failure to follow this
warning may result in severe personal injury or death.
•
Disconnect HVPDB A/C IMC high-voltage C1917F.
•
Reinstall the HVPDB cover.
•
Reconnect the 12-volt auxiliary battery negative cable.
•
With key ON, measure the voltage between circuit 3150 (DB wire) and
circuit 3151 (W wire) on HVPDB A/C IMC high-voltage C1917.
•
Is the voltage greater than 300 volts?
F11 CHECK HIGH-VOLTAGE FUSE
•
With key OFF, disconnect the 12-volt auxiliary battery negative cable.
Yes =
REPLACE the 25A A/C
fuse. GO to F12.
•
Disconnect high-voltage auxiliary load in-line C1935 on the traction
No =
REPLACE the HVPDB.

Connect the probes of the Capacitor Discharge Tool to circuit 3150 (DB
No =
GO to F13.
wire) and circuit 3151 (W wire) on HVPDB A/C IMC C1917M and
allow the voltage on the DVOM to discharge to 0 volt.
•
Measure the resistance between circuit 3150 (DB wire) and circuit 3151
(W wire) on HVPDB A/C IMC C1917M.
•
Is the resistance less than 30 ohms?
F13 CHECK HVPDB FOR SHORT
•
Measure the resistance between circuit 3150 (DB wire) and circuit 3151
Yes =
(W wire) on HVPDB A/C IMC high-voltage C1917F.
•
Is the resistance greater than 10,000 ohms?
No =
