U0017-CAN INTERIOR BUS (-) CIRCUIT HIGH





For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .


- When Monitored:
With the ignition on.

- Set Condition:
The TIPM detects a high voltage on either CAN Interior Bus (125K) circuits for over 100ms.






Diagnostic Test


1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read active DTC's.
Does the scan tool display this DTC as active?

Yes


- Go To 2


No


- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.


2. ANY CAN INTERIOR BUS (125K) MODULE- INTERNAL SHORT
NOTE: When performing this step, turn the ignition off (wait one minute) before disconnecting any module. When the module is disconnected turn the ignition on.

NOTE: This step is to determine if the fault is internal within a module.

While monitoring the scan tool, disconnect each CAN Interior Bus (125K) module (except the TIPM itself), one at a time.
Check for this DTC to become active after disconnecting each CAN Interior Bus (125K) module the vehicle is equipped with.

NOTE: If the DTC becomes stored when a particular module is disconnected, that module is causing the DTC to set.

With all the CAN Interior Bus modules disconnected does the scan tool display this DTC as active?

Yes


- Go To 3


No


- Replace the module that when disconnected caused this DTC to become stored.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.


3. (D265) CAN INTERIOR BUS (125K)(+) CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the TIPM C7 Harness connector.

NOTE: Ensure ALL CAN Interior Bus modules are disconnected before proceeding

Measure the resistance between ground and the (D265) CAN Interior Bus (125K)(+) circuit (Cavity 2) in the Door Module C3 harness connector.
Is the resistance below 10,000.0 ohms?

Yes


- Repair the (D265) CAN Interior Bus (125K)(+) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.


No


- Go To 4


4. (D264) CAN INTERIOR BUS (125K)(-) CIRCUIT SHORTED TO GROUND
Measure the resistance between ground and the (D264) CAN Interior Bus (125K)(-) circuit (Cavity 1) in the Door Module harness connector.
Is the resistance below 10,000.0 ohms?

Yes


- Repair the (D264) CAN Interior Bus (125K)(-) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.


No


- Go To 5


5. (D265) CAN INTERIOR BUS (125K)(+) CIRCUIT SHORTED TO THE (D254) CAN INTERIOR BUS (-) CIRCUIT
Measure the resistance between the (D265) CAN Interior Bus (125K)(+) circuit (Cavity 2) and the (D254) CAN Interior Bus (125)(-) circuit (Cavity 1) in the Door Module C3 harness connector.
Is the resistance below 10,000.0 ohms?

Yes


- Repair the (D265) CAN Interior Bus (125K)(+) circuit for a short to the (D264) CAN Interior Bus (125K)(-) circuit.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.


No


- Go To 6


6. (D264) CAN INTERIOR BUS (125K)(-) CIRCUIT SHORTED TO VOLTAGE
Turn the ignition on.
Measure the voltage between ground and the (D264) CAN Interior Bus (125K)(-) circuit (Cavity 1) in the Door Module harness connector.
Is the voltage above 0.02 volts?

Yes


- Repair the (D264) CAN Interior Bus (125K)(-) circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.


No


- Go To 7


7. (D265) CAN INTERIOR BUS (125K)(+) CIRCUIT SHORTED TO VOLTAGE
Measure the voltage between ground and the (D265) CAN Interior Bus (125K)(+) circuit (Cavity 2) in the Door Module harness connector.
Is the voltage above 0.02 volts?

Yes


- Repair the (D264) CAN Interior Bus (125K)(-) circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.


No


- Inspect the wiring and all module connectors for damage or shorted pins. If OK, replace and program the Totally Integrated Power Module.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.
