Symptom:

BCM MESSAGES NOT RECEIVED (EXPORT ONLY)

When Monitored and Set Condition:

BCM MESSAGES NOT RECEIVED (EXPORT ONLY)

When Monitored:

Continuously with the ignition on.

Set Condition:

The RKE/Thatcham Alarm Module does not receive any messages from

the BCM for at least 5 seconds.

POSSIBLE CAUSES

INTERMITTENT CONDITION

BCM COMMUNICATION FAILURE

PCI BUS CIRCUIT OPEN

RKE/THATCHAM ALARM MODULE - INTERNAL MALFUNCTION

TEST

ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRBIII

t, attempt to communicate with the BCM.

Was the DRBIII

t able to communicate with the BCM?

All

Yes

→ Go To 2

No

→ Refer to the Communication category and perform the appropri-

ate symptom.
Perform VTSS VERIFICATION TEST - 1A.

2

Turn the ignition on.
With the DRBIII

t, attempt to communicate with the RKE/Thatcham Alarm Module.

Was the DRBIII

t able to communicate with the RKE/Thatcham Alarm Module?

All

Yes

→ The condition that caused this symptom is currently not present.

Inspect the related wiring harness for a possible intermittent
condition.
Perform VTSS VERIFICATION TEST - 1A.

No

→ Go To 3

3

Turn the ignition off.
Disconnect the negative battery cable.
Disconnect the Thatcham Alarm Module 16-way harness connector.
Disconnect the DRBIII

t from the data link connector.

Measure the resistance of the PCI Bus circuit between the data link connector and
the Thatcham Alarm Module connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Replace the RKE/Thatcham Alarm Module.

Perform VTSS VERIFICATION TEST - 1A.

No

→ Repair the PCI Bus circuit for an open.

Perform VTSS VERIFICATION TEST - 1A.

VEHICLE THEFT/SECURITY

Symptom:

INTERNAL EEPROM WRITE ERROR (EXPORT ONLY)

When Monitored and Set Condition:

INTERNAL EEPROM WRITE ERROR (EXPORT ONLY)

When Monitored:

During a EEPROM write event.

Set Condition:

If the EEPROM write time exceeds 16ms.

POSSIBLE CAUSES

INTERMITTENT CONDITION

RKE/THATCHAM ALARM MODULE - INTERNAL MALFUNCTION

TEST

ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRBIII

t, erase the current RKE/Thatcham Alarm Module DTC’s.

Turn the ignition off, wait 10 seconds then turn the ignition on.
With the DRBIII

t, read the current RKE/Thatcham Alarm Module DTC’s.

Does the DRBIII

t display: INTERNAL EEPROM WRITE ERROR?

All

Yes

→ Replace the RKE/Thatcham Alarm Module.

Perform VTSS VERIFICATION TEST - 1A.

No

→ The condition that caused this symptom is currently not present.

Perform VTSS VERIFICATION TEST - 1A.

VEHICLE THEFT/SECURITY

Symptom:

INTERNAL TRANSMIT FAILURE (EXPORT ONLY)

When Monitored and Set Condition:

INTERNAL TRANSMIT FAILURE (EXPORT ONLY)

When Monitored:

Continuously with the ignition on during a message transmission.

Set Condition:

After 8 internal attempts to transmit the RKE/Thatcham Alarm Module

Bus messages.

POSSIBLE CAUSES

INTERMITTENT CONDITION

t, read the current RKE/Thatcham Alarm Module DTC’s.

Does the DRBIII

t display: INTERNAL TRANSMIT FAILURE?

All

Yes

→ Replace the RKE/Thatcham Alarm Module.

Perform VTSS VERIFICATION TEST - 1A.

No

→ The condition that caused this symptom is currently not present.

Inspect the related wiring harness for a possible intermittent
condition.
Perform VTSS VERIFICATION TEST - 1A.

VEHICLE THEFT/SECURITY

Symptom:

INTERNAL ULTRASONIC FAULT (EXPORT ONLY)

When Monitored and Set Condition:

INTERNAL ULTRASONIC FAULT (EXPORT ONLY)

When Monitored:

During the initial 6 seconds of an ignition on cycle.

Set Condition:

After 5 consecutive ignition cycles without detecting any ultrasonic

movement.
