Dodge Caliber. Manual — part 262
3.
(Z965) GROUND CIRCUIT OPEN
Using a 12-volt test light connected to 12-volts, check the (Z965)
ground circuit.
Does the test light illuminate brightly?
Yes
>> Go To 4
No
>> Repair the (Z965) ground circuit for an open.
Perform the BODY VERIFICATION TEST – VER 1. (Refer
to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).
4.
(D55) AND (D54) CAN B BUS CIRCUITS OPEN
Turn the ignition on.
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 Satellite Receiver in accordance with the ser-
vice information.
Perform the BODY VERIFICATION TEST – VER 1. (Refer
to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).
No
>> Repair the (D55) and (D54) CAN B Bus circuits for an open.
Inspect the connector for damage.
Perform the BODY VERIFICATION TEST – VER 1. (Refer
to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).

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 sensor?
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.
(F202) IGNITION SWITCH OUTPUT CIRCUIT OPEN OR SHORTED
Turn the ignition off.
Disconnect the Steering Angle Sensor harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, check the (F202) Ignition
Switch Output circuit.
Does the test light illuminate brightly?
Yes
>> Go To 3
No
>> Repair the (F202) Ignition Switch Output circuit for an open
or short.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE)

3.
(Z937) GROUND CIRCUIT OPEN
Turn the ignition off.
Using a 12-volt test light connected to 12-volts, check the (Z937)
ground circuit.
Does the test light illuminate brightly?
Yes
>> Go To 4
No
>> Repair the (Z937) ground circuit for an open.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE)
4.
(D265) CAN C BUS (+) CIRCUIT OPEN
Disconnect the TIPM C2 harness connector.
Measure the resistance of the (D265) CAN C Bus (+) circuit between
the TIPM C2 harness connector and the Steering Angle Sensor connec-
tor.
Is resistance below 5.0 ohms?
Yes
>> Go To 5
No
>> Repair the (D265) CAN C Bus (+) circuit for an open.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE)
