Dont disagree, even if the "relays" are solid state they can still be repaired but it wont be cheap.
The manual does refer to the TPIM as housing all the relays..that might be lingo and not technically correct.
DESCRIPTION
The power distribution system for this vehicle consists of the Totally Integrated Power Module (TIPM) and related fuses, relays and wiring connectors.
OPERATION
The power distribution system for this vehicle is designed to provide safe, reliable, centralized, and convenient to access, distribution of the electrical current required to operate all of the many standard and optional factory-installed electrical and electronic powertrain, chassis, safety, comfort and convenience systems. At the same time, these systems were designed to provide centralized locations for conducting diagnosis of faulty circuits, and for sourcing the additional current requirements of many aftermarket vehicle accessory and convenience items.
These power distribution systems also incorporate various types of circuit control and protection features, including fuses and relays.
Buggar you cant just pull or tap a transistor of Fet to check operation haha!
