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. Standard Resistance: Tester Connection | Condition | Specified Condition | x2-1 (+) - t5-1 (CBI) | Auxiliary battery voltage not applied between terminals y1-4 (SMRB) and y1-2 (GND) | 10 kΩ or higher | Auxiliary battery voltage applied between terminals y1-4 (SMRB) and y1-2 (GND) | Below 1 Ω | (2) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | y1-4 (SMRB) - y1-2 (GND) | -40 to 80°C (-40 to 176°F) | 20.6 to 40.8Ω | If the result is not as specified, replace the hybrid battery junction block assembly. | | *1 | x2-1 (+) | *2 | t5-1 (CBI) | *3 | y1 | *a | Component without harness connected (Hybrid Battery Junction Block Assembly) | | |
(b) Inspect SMRG: (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | x3-1 (-) - t6-1 (CEI) | Auxiliary battery voltage not applied between terminals y1-1 (SMRG) and y1-2 (GND) | 10 kΩ or higher | Auxiliary battery voltage applied between terminals y1-1 (SMRG) and y1-2 (GND) | Below 1 Ω | (2) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | y1-1 (SMRG) - y1-2 (GND) | -40 to 80°C (-40 to 176°F) | 20.6 to 40.8Ω | If the result is not as specified, replace the hybrid battery junction block assembly. | | *1 | x3-1 (-) | *2 | t6-1 (CEI) | *3 | y1 | *a | Component without harness connected (Hybrid Battery Junction Block Assembly) | | |
(c) Inspect SMRP: (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | x3-1 (-) - t6-1 (CEI) | Auxiliary battery voltage not applied between terminals y1-3 (SMRP) and y1-2 (GND) | 10 kΩ or higher | Auxiliary battery voltage applied between terminals y1-3 (SMRP) and y1-2 (GND) | 28.5 to 31.5 Ω | (2) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | y1-3 (SMRP) - y1-2 (GND) | -40 to 80°C (-40 to 176°F) | 140 to 290Ω | If the result is not as specified, replace the hybrid battery junction block assembly. | | *1 | x3-1 (-) | *2 | t6-1 (CEI) | *3 | y1 | *a | Component without harness connected (Hybrid Battery Junction Block Assembly) | | |
