No Response from Sunroof Module






For a complete wiring diagram, refer to.






Test Step 1 - TEST FOR INTERMITTENT CONDITION

• Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.

• Turn the ignition on.

• Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

• With the scan tool, read the module status.

• Check the TIPM for any active CAN hardware DTCs, perform DTC before proceeding.

Does the scan tool indicate that the module is active on the bus?

Yes

• 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 connectors for broken, bent, pushed out, and corroded terminals.

No

• Go to Test Step 2

Test Step 2 - CHECK THE (A906) FUSED IGNITION SWITCH OUTPUT (RUN/ACC) CIRCUIT FOR AN OPEN OR SHORT







• Turn the ignition off.

• Disconnect the Sunroof Module harness connector.

• Turn the ignition on.

• Using a 12-volt test light connected to ground, check the (A906) Fused Ignition Switch Output (Run/Acc) circuit.

Does the test light illuminate brightly?

Yes

• Go to Test Step 3

No

• Repair the open or short in the (A906) Fused Ignition Switch Output (Run/Acc) circuit.

• Perform the Body Verification Test. Refer to => [ Body Verification Test ] Body Interior.

Test Step 3 - CHECK THE (Z910) GROUND CIRCUIT FOR AN OPEN







• Turn the ignition off.

• Using a 12-volt test light connected to 12-volts, check the (Z910) Ground circuit.

Does the test light illuminate brightly for each circuit?

Yes

• Go to Test Step 4

No

• Repair the open in the (Z910) Ground circuit.

• Perform the Body Verification Test. Refer to => [ Body Verification Test ] Body Interior.

Test Step 4 - CHECK THE (D265) OR (D264) CAN INTERIOR BUS (125K) CIRCUIT FOR AN OPEN







• Measure the resistance of the (D264) CAN Interior Bus (-) (125K) circuit between the TIPM C7 harness connector and the Sunroof Module harness connector.

• Measure the resistance of the (D265) CAN Interior Bus (+) (125K) circuit between the TIPM C7 harness connector and the Sunroof Module harness connector.

Are the resistances below 5.0 Ohms?

Yes

• Replace the Sunroof Module in accordance with the Service Information.

• Perform the Body Verification Test. Refer to => [ Body Verification Test ] Body Interior.

No

• Repair the open in the (D265) or (D264) CAN Interior Bus (125K) circuit. Inspect the connector for damage.

• Perform the Body Verification Test. Refer to => [ Body Verification Test ] Body Interior.
