TEST

ACTION

APPLICABILITY

WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
NOTE: The conditions that set the DTC are not present at this time.The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, monitor the DRB
parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DTC When Monitored and Set Conditions. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Were any of the above conditions present?

All

Yes

→ Repair as necessary.

Perform ROAD TEST VERIFICATION - VER-2.

→ Test Complete.

ACTION

APPLICABILITY

NOTE: If DTC P0560-SYSTEM VOLTAGE TOO HIGH is present with this
DTC, perform diagnostics for P0560 first.
NOTE: If the ECM detects and stores a DTC, the ECM also stores the
engine/vehicle operating conditions under which the DTC was set. Some of
these conditions are displayed on the DRB at the same time the DTC is
displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to
duplicate these conditions may assist when checking for an active DTC.
Turn the ignition on.
With the DRBIII

t, erase the ECM DTCs.

Test drive the vehicle.
With the DRBIII

t, read the ECM DTCs.

Does the DRBIII

t display this DTC?

All

Yes

→ Go To 2

→ Go To 9

Turn the ignition off.
Remove and inspect Fuse 17 from the IPM.
Is the fuse OK?

All

Yes

→ Go To 3

→ Repair the short that caused the fuse to open and replace the fuse.

Perform ROAD TEST VERIFICATION - VER-2.

Turn the ignition off.
Disconnect the ECM harness connectors.
Using a 12-volt test light connected to 12-volts, check both of the ECM ground
circuits in ECM harness connector C1 cavities 1 and 2.
Did the test light illuminate for both cavities?

All

Yes

→ Go To 4

→ Repair the ECM Ground circuit(s) for an open.

Perform ROAD TEST VERIFICATION - VER-2.

Turn the ignition off.
Disconnect the ECM harness connectors.
Remove the ECM/PCM Relay from the IPM.
Connect a jumper wire between cavity 30 and cavity 87 of the ECM/PCM Relay
connector.
Turn the ignition on.
Measure the voltage of the Ground circuit in ECM harness connector cavity C1-20.
Is the voltage below 1.0 volt?

All

Yes

→ Go To 5

→ Repair the Ground circuit for a short to voltage.

Perform ROAD TEST VERIFICATION - VER-2.

ACTION

APPLICABILITY

Turn the ignition off.
Disconnect the ECM harness connectors.
Disconnect all components connected to the ECM/PCM Relay Output circuit. Refer to
the wiring diagrams.
Remove the ECM/PCM Relay from the IPM.
Measure the resistance between ground and the ECM/PCM Relay Output circuit at
ECM harness connector cavity C1-19.
Is the resistance above 1000 ohms?

All

Yes

→ Go To 6

→ Repair the ECM/PCM Relay Output circuit for a short to ground.

Perform ROAD TEST VERIFICATION - VER-2.

Turn the ignition off.
Disconnect the ECM harness connectors.
Measure the resistance between the Battery negative terminal and the Ground
circuit in ECM harness connector cavity C1-20.
Is the resistance below 10.0 ohms?

All

Yes

→ Go To 7

→ Repair the Ground circuit for an open.

Perform ROAD TEST VERIFICATION - VER-2.

Turn the ignition off.
Disconnect the ECM harness connectors.
