3

With the DRBIII

t, perform the SRI Memory Test a second time.

NOTE: Retest the SRI Memory two more times.
Does the DRBIII

t display Write Refused again?

All

Yes

→ Replace and program the Powertrain Control Module in accor-

dance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.

No

→ Test Complete.

4

With the DRBIII

t, perform the SRI Memory Test.

Does the DRBIII

t display SRI Mileage Invalid?

All

Yes

→ Update the mileage and retest the SRI Memory.

Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.

No

→ Go To 5

5

Compare the SRI Mileage stored with the Instrument Panel Odometer.
Is the mileage within the specified range displayed on the DRBIII

t?

All

Yes

→ Test Complete.

No

→ Update the mileage and retest the SRI Memory.

Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.

Symptom:

P1698-NO TRANSMISSION BUS MESSAGE

When Monitored and Set Condition:

P1698-NO TRANSMISSION BUS MESSAGE

When Monitored:

Equipped with automatic transmission. Engine Running Battery

voltage greater than 10 volts.

Set Condition:

No bus messages are received from the TCM for 20 seconds, two trips

required.

POSSIBLE CAUSES

PCI BUS UNABLE TO COMMUNICATE WITH DRBIII

ACTION

APPLICABILITY

1

NOTE: If P1603 or P1604 are set along with this DTC, diagnose them first
before continuing with P1698.
NOTE: Before continuing, inspect all fuses and ensure that all power and
ground circuits are operating properly.
NOTE: Check all powers and grounds to the PCM before continuing.
Turn the ignition on.
With the DRBIII

t, erase DTCs.

Start the engine, allow the engine to run for at least 20 seconds with the gear selector
in Drive. Repeat at least 2 times.
With the DRBIII

t, read DTC’s.

Does the DTC reset?

All

Yes

→ Go To 2

No

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.

Turn the ignition off.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Turn the ignition to run.
Using a 12-volt test light connected to ground, probe the (F12) Fused Ignition Switch
Output (Off-Run-Start) cavity C1-12 circuit at the appropriate terminal of the special
tool #8815.
NOTE: If the test light illuminates, wiggle the wiring harness to ensure that
the problem is not an intermittent wiring problem.
Does the test light illuminate brightly?

All

Yes

→ Go To 3

No

→ Check all related fuses. Repair the (F12) Fused Ignition Switch

Output circuit for an open.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.

Note: Determine which modules this vehicle is equipped with before begin-
ning.
Note: When attempting to communicate with any of the modules on this
vehicle, the DRB will display 1 of 2 different communication errors: a NO
RESPONSE message or a BUS +/- SIGNALS OPEN message.
Turn the ignition on.
Using the DRB, attempt to communicate with the following control modules:
Body Control Module (BCM)
Instrument Cluster (MIC)
Controller Antilock Brake (CAB)
Was the DRB able to communicate with one or more Module(s)?

All

Yes

→ Replace and program the Powertrain Control Module in accor-

dance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.

No

→ Refer to the Communication category and perform the PCI BUS

COMMUNICATION FAILURE symptom.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.
