WARNING: This page is about a different car, the 2025 Toyota Corolla Cross, 2024 Toyota Corolla Cross, and 2023 Toyota Corolla Cross. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT NO. 1 TRACTION BATTERY DEVICE BOX ASSEMBLY
- Inspect SMRB:
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
(No. 1 Traction Battery Device Box Assembly)- - Standard Resistance
Tester Connection Condition Specified Condition W7-1 (CBI) - z26-1 (+) Auxiliary battery voltage not applied between terminals O212-4 (SMRB) and O212-2 (GND) 10 kΩ or higher W7-1 (CBI) - z26-1 (+) Auxiliary battery voltage applied between terminals O212-4 (SMRB) and O212-2 (GND) Below 1 Ω - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition O212-4 (SMRB) - O212-2 (GND) -40 to 80°C (-40 to 176°F) 25.0 to 59.0 Ω If the result is not as specified, replace the No. 1 traction battery device box assembly.
- Measure the resistance according to the value(s) in the table below.
- Inspect SMRG:
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
(No. 1 Traction Battery Device Box Assembly)- - Standard Resistance
Tester Connection Condition Specified Condition W6-1 (CEI) - z23-1 (-) Auxiliary battery voltage not applied between terminals O212-6 (SMRG) and O212-2 (GND) 10 kΩ or higher W6-1 (CEI) - z23-1 (-) Auxiliary battery voltage applied between terminals O212-6 (SMRG) and O212-2 (GND) Below 1 Ω - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition O212-6 (SMRG) - O212-2 (GND) -40 to 80°C (-40 to 176°F) 25.0 to 59.0 Ω If the result is not as specified, replace the No. 1 traction battery device box assembly.
- Measure the resistance according to the value(s) in the table below.
