TEST

ACTION

APPLICABILITY

1

Ignition on, engine not running.
With the DRBIII

t, read DTCs and record the related Freeze Frame data.

Is the Good Trip Counter displayed and equal to zero?

All

Yes

→ Go To 2

No

→ Refer to the INTERMITTENT CONDITION Symptom (Diagnos-

tic Procedure).
Perform POWERTRAIN VERIFICATION TEST VER - 6.

2

Turn the ignition off.
Disconnect the Leak Detection Pump electrical harness connector.

t, actuate the Leak Detection Pump.

Using a 12-volt test light connected to ground, check the (K125) Generator Source
circuit at the LDP connector.
Does the test light illuminate brightly?

All

Yes

→ Go To 3

No

→ Repair the open in the (K125) Generator Source circuit.

Perform POWERTRAIN VERIFICATION TEST VER - 6.

ACTION

APPLICABILITY

3

Turn the ignition off.
Connect a 12-volt test light to a good 12-volt source.
Ignition on, engine not running.
With the DRBIII

t, actuate the Leak Detection Pump.

Probe the (K106) LDP Solenoid Control circuit with the test light while the Pump is
actuating.
Does the test light blink?

All

Yes

→ Go To 4

No

→ Go To 5

If there are no possible causes remaining, view repair.

All

Repair

Replace the Leak Detection Pump.
Perform POWERTRAIN VERIFICATION TEST VER - 6.

5

Turn the ignition off.
Disconnect the PCM harness connectors.
Measure the resistance of the (K106) LDP Solenoid Control circuit from the PCM
harness connector to the LDP harness connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Go To 6

No

→ Repair the open in the (K106) Leak Detection Pump Solenoid

Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 6.

6

Measure the resistance between ground and the (K106) LDP Solenoid Control circuit.
Is the resistance below 100 ohms?

All

Yes

→ Repair the short to ground in the (K106) LDP Solenoid Control

circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 6.

No

→ Go To 7

7

NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.

All

Repair

Replace and program the Powertrain Control Module per Service
Information.
Perform POWERTRAIN VERIFICATION TEST VER - 6.

Symptom:

P1499-HYDRAULIC FAN SOLENOID CIRCUIT

When Monitored and Set Condition:

P1499-HYDRAULIC FAN SOLENOID CIRCUIT

When Monitored:

Ignition on and engine running.

Set Condition:

An open or shorted condition in the Hydraulic Fan Solenoid control circuit

is detected by the Powetrain Control Module.

POSSIBLE CAUSES

RADIATOR FAN INOP

(K342) FUSED ASD RELAY OUTPUT CIRCUIT

(C240) COOLING FAN CONTROL CIRCUIT OPEN

(C240) COOLING FAN CONTROL CIRCUIT SHORTED TO GROUND

PCM

TEST

ACTION

APPLICABILITY

1

Ignition on, engine not running.
With the DRBIII

t, perform the Hydraulic Fan Solenoid Test found under Engine Test

and Systems Test.
Does the Radiator Fan operate properly?

All

Yes

→ Refer to the INTERMITTENT CONDITION Symptom (Diagnos-

tic Procedure).
Perform POWERTRAIN VERIFICATION TEST VER - 2.

No

→ Go To 2

2

Turn the ignition off.
Disconnect the Fan Solenoid harness connector.
Ignition on, engine not running.
With the DRBIII

t, actuate the ASD Relay.

Using a 12-volt test light connect to ground, probe the (K342) Fused ASD Relay
Output circuit at the fan solenoid.
Does the test light illuminate brightly when the ASD Relay is actuated?

All

Yes

→ Go To 3

No

→ Repair the open or short to ground in the (K342) Fused ASD Relay

Output circuit. Inspect the related fuse and repair as necessary.
Perform POWERTRAIN VERIFICATION TEST VER - 2.
