under VERIFICATION TESTS.
- Turn ignition on. Raise passenger seat to highest position to gain access to seat components and connectors. Turn ignition off. Disconnect passenger heated seat cushion 4-pin connector. Turn ignition on. Turn passenger heated seat switch on. Measure voltage between ground and passenger heated seat cushion 4-pin connector terminal "D", passenger seat temperature 5-volt supply circuit (Black/Light Green wire). See Figure . If voltage is more than 5.5 volts, leave passenger heated seat cushion 4-pin connector disconnected, and go to next step. If voltage is 5.5 volts or less, leave passenger heated seat cushion 4-pin connector disconnected, and go to step 3 .
- Turn ignition off. Raise driver seat to highest position to gain access to seat components and connectors. Disconnect Memory Heated Seat/Mirror Module (MHSMM) connector C2. Turn ignition on. Measure voltage between ground and passenger heated seat cushion 4-pin connector terminal "D", passenger seat temperature 5-volt supply circuit (Black/Light Green wire). If any voltage exists, repair short to voltage in Black/Light Green wire. If no voltage exists, replace MHSMM.
- Turn ignition off. Raise driver seat to highest position to gain access to seat components and connectors. Disconnect Memory Heated Seat/Mirror Module (MHSMM) connector C1. Turn ignition on. Measure voltage between ground and passenger heated seat cushion 4-pin connector terminal "C", passenger seat temperature sensor input circuit (Tan/Dark Blue wire). If any voltage exists, repair short to voltage in Tan/Dark Blue wire. If no voltage exists, replace passenger heated seat cushion.
