Power Steering
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DTC C1778 POWER STEERING FAILURE
TEST STEP
ACTION TO TAKE
A10 CHECK CIRCUIT 3023 (BK/O) FOR OPEN
•
With key OFF, disconnect power steering assembly C1992 and measure
Yes =
GO to A11.
the resistance of the BK/O wire between pin 17 on the power steering
assembly C1992 and BOB pin 99.
•
Is the resistance less than 5 ohms?
No =
REPAIR the BK/O wire.
A11 CHECK LOW VOLTAGE POWER TO POWER STEERING
ASSEMBLY
•
With key ON, measure the voltage between pin 10 (LB/PK wire), pin 21
Yes =
GO to A12.
(LB/PK wire) on the power steering assembly C1992 and ground.
•
Are the voltages greater than 10 volts?
No =
REPAIR the LB/PK wire(s)
in question.
A12 CHECK HIGH VOLTAGE POSITIVE BUS TO POWER
STEERING ASSEMBLY FOR OPEN
•
Disconnect the 12-volt auxiliary battery negative cable.
Yes =
REPLACE the power
steering assembly.
No =
GO to A13.
WARNING: The following test steps contain high-voltage
procedures. High-voltage insulated safety gloves and face shield must
be worn when carrying out the following steps. Do not attempt to
check for high-voltage power at the power steering assembly
high-voltage connector. The close proximity of the connector pins may
cause an electrical arc. Failure to follow this warning may result in
severe personal injury or death.
•
Disconnect power steering assembly high-voltage C1895.
•
Disconnect high-voltage auxiliary load in-line C1935 on the traction
battery support tray.
•
Measure the resistance between circuit 3140 (BK wire) on power steering
assembly C1895F and circuit 3132 (Y wire) on high-voltage auxiliary
load in-line C1935M.
•
Is the resistance less than 5 ohms?
A13 CHECK HIGH-VOLTAGE FUSE
NOTE: If the 10A fuse is open, DO NOT replace the fuse until the cause
Yes =
REPLACE the 10A PWR
of the short is found and repaired. Replacing the fuse prior to repairing the
STR fuse. GO to A14.
short will cause contactor failure.
•
Disconnect all high-voltage power distribution box (HVPDB)
high-voltage connectors.
•
Measure the resistance of the 10A PWR STR fuse.
No =
REPLACE the HVPDB.
•
Is the resistance greater than 1,000 ohms?
REFER to
or
A14 CHECK POWER STEERING ASSEMBLY FOR CAPACITOR
DISCHARGE FAILURE
Yes =
REPLACE the power
steering assembly.
WARNING: Carefully probe the terminals of the power steering
assembly. The power steering assembly contains high-voltage
capacitors that can retain high voltage if there is a capacitor discharge
failure. Shorting the probes together may cause an electrical arc.
•
Measure the voltage between circuit 3140 (BK wire) terminal and circuit
3141 (W wire) terminal on power steering assembly C1895M.
•
Is the voltage greater than 0 volts?
No =
GO to A15.
A15 CHECK POWER STEERING ASSEMBLY FOR SHORT
