INSPECTION
PROCEDURE
1. INSPECT HV BATTERY JUNCTION BLOCK ASSEMBLY
(a) Inspect SMRB:
(1) Measure the resistance according to the value(s) in the table below.
| *a | Component without harness connected (HV Battery Junction Block Assembly) | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| y18-1 (+) - a2-1 (CBI) | Auxiliary battery voltage not applied between terminals N22-1 (SMRB) and N22-3 (GND) | 10 kΩ or higher |
| Auxiliary battery voltage applied between terminals N22-1 (SMRB) and N22-3 (GND) | Below 1 Ω |
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| N22-1 (SMRB) - N22-3 (GND) | -40 to 80°C (-40 to 176°F) | 19.0 to 59.0 Ω |
If the result is not as specified, replace the HV battery junction block assembly.
(b) Inspect SMRG:
(1) Measure the resistance according to the value(s) in the table below.
| *a | Component without harness connected (HV Battery Junction Block Assembly) | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| y12-1 (-) - a3-1 (CEI) | Auxiliary battery voltage not applied between terminals N22-4 (SMRG) and N22-3 (GND) | 10 kΩ or higher |
| Auxiliary battery voltage applied between terminals N22-4 (SMRG) and N22-3 (GND) | Below 1 Ω |
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| N22-4 (SMRG) - N22-3 (GND) | -40 to 80°C (-40 to 176°F) | 19.0 to 59.0 Ω |
If the result is not as specified, replace the HV battery junction block assembly.
(c) Inspect SMRP:
(1) Measure the resistance according to the value(s) in the table below.
| *a | Component without harness connected (HV Battery Junction Block Assembly) | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| y12-1 (-) - a3-1 (CEI) | Auxiliary battery voltage not applied between terminals N22-2 (SMRP) and N22-3 (GND) | 10 kΩ or higher |
| Auxiliary battery voltage applied between terminals N22-2 (SMRP) and N22-3 (GND) | 24.3 to 29.7 Ω |
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| N22-2 (SMRP) - N22-3 (GND) | -40 to 80°C (-40 to 176°F) | 140 to 290 Ω |
If the result is not as specified, replace the HV battery junction block assembly.
