MODULE

TEST

ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRBIII

t, attempt to communicate with the PCM.

With the DRBIII

t, select System Monitors then J1850 Module Scan.

Is the PCM one of the modules present on the bus?

All

Yes

→ Go To 3

No

→ Refer to the Communication category for the related symptom(s).

Perform BODY VERIFICATION TEST - VER 1.

3

With the DRBIII

t, erase DTC’s.

Cycle the ignition switch from off to on and wait approximately 1 minute.
With the DRBIII

t, read DTC’s.

Did this DTC reset?

All

Yes

→ Replace and program the Hands Free Module in accordance with

the service information.
Perform BODY VERIFICATION TEST - VER 1.

No

TELECOMMUNICATION

Symptom List:

INITIALIZATION FAULT
TIRE SENSOR 1 LOW PRESSURE ALERT
TIRE SENSOR 1 TRANSMIT FAILURE
TIRE SENSOR 2 LOW PRESSURE ALERT
TIRE SENSOR 2 TRANSMIT FAILURE
TIRE SENSOR 3 LOW PRESSURE ALERT
TIRE SENSOR 3 TRANSMIT FAILURE
TIRE SENSOR 4 LOW PRESSURE ALERT
TIRE SENSOR 4 TRANSMIT FAILURE

Test Note:

All symptoms listed above are diagnosed using the same tests.

The title for the tests will be INITIALIZATION FAULT.

When Monitored and Set Condition:

INITIALIZATION FAULT

When Monitored:

Ignition ON.

Set Condition:

Fault is set when there is a failure of automatically learning TPM sensor

ID’s in the SKREEM receiver. Automatic initialization is performed after each ignition
cycle and vehicle speed is greater than 32 km/h (20 MPH) within 10 minutes.

TIRE SENSOR 1 LOW PRESSURE ALERT

When Monitored:

Ignition ON.

Set Condition:

Fault is set when there is a low tire pressure condition or sensor pressure

measurement failure from the number 1 Sensor/Transmitter.

TIRE SENSOR 1 TRANSMIT FAILURE

When Monitored:

Ignition ON

Set Condition:

Fault is set when the SKREEM does not receive eight consecutive RF

transmissions from the number 1 Sensor/Transmitter.

TIRE SENSOR 2 LOW PRESSURE ALERT

When Monitored:

Ignition ON.

Set Condition:

Fault is set when there is a low tire pressure condition or sensor pressure

measurement failure from the number 2 Sensor/Transmitter.

TIRE SENSOR 2 TRANSMIT FAILURE

When Monitored:

Ignition ON.

Set Condition:

Fault is set when the SKREEM does not receive eight consecutive RF

transmissions from the number 2 Sensor/Transmitter.

1138

TIRE PRESSURE MONITORING

TIRE SENSOR 3 LOW PRESSURE ALERT

When Monitored:

Ignition ON.

Set Condition:

Fault is set when there is a low tire pressure condition or sensor pressure

measurement failure from the number 3 Sensor/Transmitter.

TIRE SENSOR 3 TRANSMIT FAILURE

When Monitored:

Ignition ON.

Set Condition:

Fault is set when the SKREEM does not receive eight consecutive RF

transmissions from the number 3 Sensor/Transmitter.

TIRE SENSOR 4 LOW PRESSURE ALERT

When Monitored:

Ignition ON.

Set Condition:

Fault is set when there is a low tire pressure condition or sensor pressure

measurement failure from the number 4 Sensor/Transmitter.

TIRE SENSOR 4 TRANSMIT FAILURE

When Monitored:

Ignition ON.

Set Condition:

Fault is set when the SKREEM does not receive eight consecutive RF

transmissions from the number 4 Sensor/Transmitter.

POSSIBLE CAUSES

TIRE SENSOR LOW PRESSURE ALERT

SENSOR/TRANSMITTER INTERNAL FAULT

TEST

ACTION

APPLICABILITY

1

NOTE: If the TPM indicator is illuminated, check for a low tire pressure
condition. If the TPM indicator is flashing, check for DTC’s.
NOTE: The below test is to locate the Tire Pressure Sensor/Transmitter.
NOTE: If the tires have been rotated, the Tire Pressure Sensor/Transmitters
are no longer in sequence from the factory. Faults are linked to Sensor/
Transmitter ID’s.
NOTE: You must determine which Tire Pressure Sensor/Transmitter has set
the fault or alert before diagnosing the system correctly.
NOTE: Set ALL tire pressures to recommended specifications and recheck
for faults/alerts.
The fault will set within two minutes when at 20 PSI.
Starting with the left front wheel, deflate the tire down to 20 PSI and wait 2 minutes.
If the TPMS fault was detected and associated to this Sensor/Transmitter, it would
correspond to the left front Sensor/Transmitter.
If the TPMS fault was detected and not associated to this Sensor/Transmitter, repeat
the process until the faulty Sensor/Transmitter has been identified.
NOTE: Once a fault/alert has set, it will establish the location of the Tire
Pressure Sensors/Transmitter. Repeat steps until the applicable Tire Pres-
sure Sensor/Transmitter has been located.
Perform this procedure prior to Symptom diagnosis.

NOTE: The DTC can be caused by many different factors and might not be
a Sensor/Transmitter or SKREEM fault.
NOTE: Interference from other elements will over power the Sensor/
Transmitter RF frequency making erratic operation to the TPMS.
Cycle the ignition switch from OFF to ON.
With the DRBIII

t, read DTC’s.

Does the DRBIII

t display any TIRE SENSOR TRANSMIT FAILURE or INITIAL-

IZATION FAULT DTC’s?

All

Yes

→ Go To 4

No

→ Go To 3

3

Cycle the ignition switch from OFF to ON.
NOTE: Correct all tire pressure to recommended specifications and wait 2
minutes.
Drive the vehicle for 10 minutes at 20 mph (32km/h). The Sensors/transmitters will
be in drive mode operation.
With the DRBIII

t, read DTC’s.

Does the DRBIII

t display TIRE SENSOR LOW PRESSURE ALERT?

All

Yes

→ Check and adjust ALL tire pressures. Check connectors - Clean/

repair as necessary. If ok, replace and program the Tire Pressure
Sensor/Transmitter in accordance with the Service Information.
Perform TIRE PRESSURE VERIFICATION TEST - VER 1 -
SKREEM.

No

→ Go To 4
