B193C - Left Power Sliding Door Switch Circuit High






For a complete wiring diagram, refer to.

• When Monitored: Whenever the totally integrated power module is awake.

• Set Condition: When the TIPM senses more than 6 volts on the left sliding door pillar switch MUX circuit for longer than 10 seconds.






Test Step 1 - DTC Present

• With the scan tool, record DTCs.

• Erase DTCs.

• Turn the ignition OFF, wait 10 seconds, then turn the ignition ON.

• Operate the left power sliding door several times from the left power sliding door b-pillar switch.

• With the scan tool, read DTCs.

Does the scan tool display this DTC as Active?

Yes

• Go to Test Step 2.

No

• Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent condition.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 2 - Test the Left Sliding Door Pillar Switch MUX Circuit for a Short to Voltage






• Disconnect the TIPM harness connector.

• Turn the ignition ON.

• Measure the voltage between ground and the left sliding door pillar switch MUX circuit.

Is there any voltage present?

No

• Go to Test Step 3.

Yes

• Repair the MUX circuit for a short to voltage.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 3 - Test the Left Sliding Door Pillar Switch MUX Circuit for an Open






• Turn the ignition OFF.

• Disconnect the left power sliding door b-pillar switch 4-way harness connector.

• Measure the resistance of the left sliding door pillar switch MUX circuit between the left power sliding door b-pillar switch 4-way harness connector and the TIPM harness connector.

Is the resistance less than 5.0 ohms?

No

• Repair the circuit for an open.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Yes

• Go to Test Step 4.

Test Step 4 - Test the Door Lock Switch Return Circuit for an Open







• Measure the resistance of the switch return circuit between the left power sliding door b-pillar switch 4-way harness connector and the TIPM harness connector.

Is the resistance less than 5.0 ohms?

No

• Repair the circuit for an open.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Yes

• Replace the TIPM.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
