B193B - Left Power Sliding Door Switch Circuit Low






For a complete wiring diagram, refer to.

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

• Set Condition: When the TIPM senses low voltage on the left sliding door pillar 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 Power Sliding Door B-Pillar Switch for a Short to Ground

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

No

• Go to Test Step 4.

Test Step 4 - Left Sliding Door Pillar MUX Circuit Short to the Switch Return







• Measure the resistance between the switch ground circuit and the left sliding door pillar switch MUX circuit in the switch connector.

Is the resistance less than 10k ohms?

Yes

• Repair the circuit for a short to the switch ground circuit.

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

No
