INSPECTION
PROCEDURE
1. INSPECT NO. 1 FOLD SEAT SWITCH ASSEMBLY (for Front Side)
(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | 1 (HRSR) - 7 (E) | RETURN RH switch pressed | Below 1 Ω | 6 (HFSR) - 7 (E) | FOLD RH switch pressed | 1 (HRSR) - 7 (E) 3 (HRSL) - 7 (E) 6 (HFSR) - 7 (E) 8 (HFSL) - 7 (E) | OFF | 10 kΩ or higher | 3 (HRSL) - 7 (E) | RETURN LH switch pressed | Below 1 Ω | 8 (HFSL) - 7 (E) | FOLD LH switch pressed | If the result is not as specified, replace the No. 1 fold seat switch assembly. | | *a | Component without harness connected (No. 1 Fold Seat Switch Assembly) | | |
(b) Apply auxiliary battery voltage to the switch connector and check that the No. 1 fold seat switch assembly illuminates.
OK:
Condition | Specified Condition |
Auxiliary battery positive (+) → Terminal 5 (+B) Auxiliary battery negative (-) → Terminal 4 (ILL-) | Illumination illuminates |
If the result is not as specified, replace the No. 1 fold seat switch assembly.
2. INSPECT REAR POWER SEAT SWITCH (for Rear Seat)
(a) for LH Side:
(1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | 2 (FLDL) - 7 (E) | FOLD switch pressed | Below 1 Ω | 2 (FLDL) - 7 (E) 3 (RTNL) - 7 (E) | OFF | 10 kΩ or higher | 3 (RTNL) - 7 (E) | RETURN switch pressed | Below 1 Ω | If the result is not as specified, replace the rear power seat switch. | | *a | Component without harness connected (Rear Power Seat Switch) | | |
(b) for RH Side:
(1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | 2 (RTNR) - 7 (E) | RETURN switch pressed | Below 1 Ω | 2 (RTNR) - 7 (E) 3 (FLDR) - 7 (E) | OFF | 10 kΩ or higher | 3 (FLDR) - 7 (E) | FOLD switch pressed | Below 1 Ω | If the result is not as specified, replace the rear power seat switch. | | *a | Component without harness connected (Rear Power Seat Switch) | | |
3. INSPECT NO. 2 FOLD SEAT SWITCH ASSEMBLY (for Rear Side)
(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | 1 (RTRN) - 7 (E) | RETURN RH switch pressed | Below 1 Ω | 6 (FOLD) - 7 (E) | FOLD RH switch pressed | 1 (RTRN) - 7 (E) 3 (RTRN) - 7 (E) 6 (FOLD) - 7 (E) 8 (FOLD) - 7 (E) | OFF | Below 1 Ω | 3 (RTRN) - 7 (E) | RETURN LH switch pressed | Below 1 Ω | 8 (FOLD) - 7 (E) | FOLD LH switch pressed | If the result is not as specified, replace the No. 2 fold seat switch assembly. | | *a | Component without harness connected (No. 2 Fold Seat Switch Assembly) | | |
(b) Apply auxiliary battery voltage to the switch connector and check that the No. 2 fold seat switch assembly illuminates.
OK:
Condition | Specified Condition |
Auxiliary battery positive (+) → Terminal 5 (+B) Auxiliary battery negative (-) → Terminal 4 (ILL-) | Illumination illuminates |
If the result is not as specified, replace the No. 2 fold seat switch assembly.
