Toyota Yaris: Seat Heater Switch / Inspection
INSPECTION
PROCEDURE
1. INSPECT SEAT HEATER SWITCH (for LH Side)
(a) Check the resistance. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition |
If the result is not as specified, replace the seat heater switch.
| H135-6 (IG) - H135-3 (E) H135-6 (IG) - H135-1 (HI) H135-4 (LO) - H135-3 (E) | "HI" switch off | 10 kΩ or higher | H135-6 (IG) - H135-3 (E) H135-6 (IG) - H135-1 (HI) H135-4 (LO) - H135-3 (E) | "HI" switch on | Below 1 Ω | H135-6 (IG) - H135-3 (E) H135-6 (IG) - H135-4 (LO) | "LO" switch off | 10 kΩ or higher | H135-6 (IG) - H135-3 (E) H135-6 (IG) - H135-4 (LO) | "LO" switch on | Below 1 Ω | |
| *a | Component without harness connected (Seat Heater Switch) | | |
(b) Check the indicator illuminates.
(1) Apply battery voltage to the seat heater switch and check that the seat heater switch indicator illuminates.
OK:
Measurement Connection | Switch Condition | Specified Condition |
If the result is not as specified, replace the seat heater switch.
|
Battery positive (+) → H135-6 (IG) Battery negative (-) → H135-3 (E) | "HI" switch on | illuminates |
Battery positive (+) → H135-6 (IG) Battery negative (-) → H135-3 (E) | "LO" switch on | illuminates |
(c) Check the illuminates.
(1) Apply battery voltage to the seat heater switch and check that the seat heater switch illuminates.
OK:
Measurement Connection | Switch Condition | Specified Condition |
If the result is not as specified, replace the seat heater switch.
|
Battery positive (+) → H135-5 (ILL+) Battery negative (-) → H135-2 (ILL-) | Always | illuminates |
2. INSPECT SEAT HEATER SWITCH (for RH Side)
(a) Check the resistance. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition |
If the result is not as specified, replace the seat heater switch.
| H134-6 (IG) - H134-3 (E) H134-6 (IG) - H134-1 (HI) H134-4 (LO) - H134-3 (E) | "HI" switch off | 10 kΩ or higher | H134-6 (IG) - H134-3 (E) H134-6 (IG) - H134-1 (HI) H134-4 (LO) - H134-3 (E) | "HI" switch on | Below 1 Ω | H134-6 (IG) - H134-3 (E) H134-6 (IG) - H134-4 (LO) | "LO" switch off | 10 kΩ or higher | H134-6 (IG) - H134-3 (E) H134-6 (IG) - H134-4 (LO) | "LO" switch on | Below 1 Ω | |
| *a | Component without harness connected (Seat Heater Switch) | | |
(b) Check the indicator illuminates.
(1) Apply battery voltage to the seat heater switch and check that the seat heater switch indicator illuminates.
OK:
Measurement Connection | Switch Condition | Specified Condition |
If the result is not as specified, replace the seat heater switch.
|
Battery positive (+) → H134-6 (IG) Battery negative (-) → H134-3 (E) | "HI" switch on | illuminates |
Battery positive (+) → H134-6 (IG) Battery negative (-) → H134-3 (E) | "LO" switch on | illuminates |
(c) Check the illuminates.
(1) Apply battery voltage to the seat heater switch and check that the seat heater switch illuminates.
OK:
Measurement Connection | Switch Condition | Specified Condition |
If the result is not as specified, replace the seat heater switch.
|
Battery positive (+) → H134-5 (ILL+) Battery negative (-) → H134-2 (ILL-) | Always | illuminates |
