Checking heater elements
- Ignition on.
Checking components and connectors
Check the connectors. Check for contact resistance. Check for oxidation. Check for loose connections.
Check the heating loop in the seat. Take readings between:
- terminals #1 and #4 on connector B for the seat heating module (SHM). Check for an open-circuit
- terminal #1 on connector B and chassis ground. Check for a short-circuit to ground
- terminal #1 on connector B and terminal #4 on connector A. Check for a short-circuit to supply voltage.
Check the heating loop in the backrest. Take readings between:
- terminals #1 and #2 on connector C for the seat heating module (SHM). Check for an open-circuit
- terminal #1 on connector C and chassis ground. Check for a short-circuit to ground
- terminal #1 on connector C and terminal #4 on connector A. Check for a short-circuit to supply voltage.
