- Turn ignition off. Disconnect driver's heated seat cushion harness connector. Turn ignition on. Turn driver's seat heater on. Measure voltage at terminal "D" (Black/Dark Green wire) at driver's heated seat cushion harness connector. See Figure . If voltage is greater than 5.5 volts, go to next step. If voltage is 5.5 volts or less, go to step 3 .
- Turn ignition off. Disconnect Memory Heated Seat/Mirror Module (MHSMM) harness connector C2. Turn ignition on. Measure voltage at terminal "D" (Black/Dark Green wire) at driver's heated seat cushion harness connector. If no voltage exists, replace MHSMM. If any voltage exists, repair short to voltage in Black/Dark Green wire between driver's heated seat cushion and MHSMM.
- Turn ignition off. Disconnect Memory Heated Seat/Mirror Module (MHSMM) harness connector C1. Turn ignition on. Measure voltage at terminal "C" (Tan/Light Blue wire) at driver's heated seat cushion harness connector. If no voltage exists, replace driver's heated seat cushion. If any voltage exists, repair short to voltage in Tan/Light Blue wire between driver's heated seat cushion and MHSMM.
