Circuit/System Testing



1. Ignition OFF, disconnect the harness connector at the appropriate E14F or E14H rear seat cushion heating element.



2. Test for less than 10 Ohms between the low reference circuit terminal D and ground.



瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit test normal, replace the K29R



rear seat heating control module.



3. Ignition ON, test for 4.8 - 5.2 V between the signal circuit terminal C and ground.



瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace



the K29R rear seat heating control module.



瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K29R rear seat



heating control module.



4. If all circuits test normal, test or replace the E14 rear seat cushion heating element.



Component Testing



E14F or E14H Seat Cushion Heating Element



1. Ignition OFF, disconnect the harness connector at the appropriate E14F or E14H rear seat cushion heating element.



2. Test for 500 Ohms - 300 kOhms between the signal circuit terminal C and the low reference circuit terminal D.



瀚慖f not within the specified range, replace the E14 rear seat cushion heating element.
