Conditions for Setting the DTC
B2425 0D or B2430 0D
By measuring current and voltage output to the seat heating elements every 10 seconds, the rear seat heating control module calculates that the
heating element resistance is above the maximum resistance.
B2425 0B, B2425 0E, B2430 0B, or B2430 0E
By measuring current and voltage output to the seat heating elements every 10 seconds, the rear seat heating control module calculates that the
heating element resistance is below the minimum resistance.
Action Taken When the DTC Sets
The heated seat function for the affected seat will be disabled.
Conditions for Clearing the DTC
* The current DTC clears when the malfunction is no longer present, and the power mode changes to OFF then back to ACC or RUN.
* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.

Circuit/System Testing
B2425 0B, B2425 0D, or B2425 0E
1. Ignition OFF, disconnect the harness connector at the E14E seat back heating element.
Note: Element resistance must be measured twice to ensure that all failure conditions are simulated. First with the seat unoccupied, then with
the seat occupied.
2. Test for 0.5 - 5 Ohms between terminal A and terminal B.
瀚慖f not within the specified range, replace the E14E seat back heating element.
3. Connect the harness connector at the E14E seat back heating element and disconnect the X2 harness connector at the K29R rear seat heating
control module.
Note: Element resistance must be measured twice to ensure that all failure conditions are simulated. First with the seat unoccupied, then with
the seat occupied.
4. Test for 1 - 7 Ohms between control circuit terminal 3 and control circuit terminal 1.
瀚慖f less than the specified range, test for a short between the control circuits. If the circuits test normal, replace the E14F seat cushion
