Measure between the (P188) Passenger Seat Heater B(+) Driver circuit at the Passenger Seat Back Pad Heater connector and the seat frame for a short to ground.
Q: Is the resistance below 1000 ohms?
YES: Repair the pigtail harness for a short to ground condition or replace the seat back heater element as necessary. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 5
5. CHECK THE PASSENGER CUSHION PAD HEATER RESISTANCE

NO: Go To 6
YES: Replace the heater element as necessary. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
6. CHECK THE PASSENGER CUSHION PAD HEATER FOR A SHORT TO GROUND
Measure between the (P188) Passenger Seat Heater B(+) Driver circuit at the Passenger Cushion Pad Heater connector and the seat frame for a short to ground.
Q: Is the resistance below 1000 ohms?
YES: Repair the pigtail harness or replace the heater element as necessary. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent short to ground. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
7. Check the (P188) Passenger Seat Heater B(+) Driver circuit for a short to ground
Disconnect the Heated Seat Module connector.
