the FCM connector and the appropriate terminal of the special tool
#8815.
Is resistance below 5.0 ohms?
Yes
>> Replace and program the Powertrain Control Module in
accordance with the service information.
Perform (NGC) POWERTRAIN VERIFICATION TEST VER
- 5.
No

Diagnostic Test
1.
TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
With the scan tool, select ECU view.
NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active
on the Bus network. A green check indicates that the module is active on the Bus network.
Does the scan tool display a red X next to the module?
Yes
>> Go To 2
No
>> The no response condition is not present at this time. Using the wiring diagram/schematic as a guide,
inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness con-
nectors for broken, bent , pushed out, and corroded terminals.
2.
(A215) FUSED B(+) CIRCUIT OPEN OR SHORTED
Turn the ignition off.
Disconnect the Passenger Memory Mirror Module harness connector.
Using a 12-volt test light connected to ground, check the (A215) Fused
B(+) circuit.
Does the test light illuminate brightly?
Yes
>> Go To 3
No
>> Repair the (A215) Fused B(+) circuit for an open or short.
Perform BODY VERIFICATION TEST - VER 1.

3.
(Z944) GROUND CIRCUIT OPEN
Using a 12-volt test light connected to 12-volts, check the (Z944)
ground circuit.
Does the test light illuminate brightly?
Yes
>> Go To 4
No
>> Repair the (Z944) ground circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
4.
(D55) AND (D54) CAN B BUS CIRCUITS OPEN
NOTE: One open circuit will not cause this condition.
Measure the voltage between the (D54) CAN B Bus (-) circuit and
ground.
Measure the voltage between the (D55) CAN B Bus (+) circuit and
ground.
Is there any voltage present on either circuit?
Yes
>> Replace the Passenger Memory Mirror Module in accor-
dance with the service information.
Perform BODY VERIFICATION TEST - VER 1.
No
>> Repair the (D55) and (D54) CAN B Bus circuits for an
open. Inspect the connector for damage.
Perform BODY VERIFICATION TEST - VER 1.
