Refer to DESCRIPTION
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0AFC-62 | Hybrid/EV Battery Sensor Module Signal Compare Failure | The difference between the voltage output by detection circuit C and the total of the voltage output by detection circuits A and B exceeds the threshold. HINT: The battery voltage sensor uses 3 voltage detection circuits (A, B and C) to detect the voltage of the battery blocks. (1 trip detection logic) |
Battery voltage sensor | Comes on | Master Warning: Comes on |
HINT:
Hybrid Battery Block 1 to 12 Voltage values smaller than 2.0 V may not be shown in the Data List because a fail-safe value is substituted.
RELATED DATA LIST
| DTC No. | Data List |
|---|---|
| P0AFC-62 | Hybrid Battery Block 1 to 12 Voltage *1 |
HINT:
- *1: Under normal conditions, the values of Hybrid Battery Block 1, 2, 11 and 12 Voltage will be approximately 16 V and Hybrid Battery Block 3, 4, 5, 6, 7, 8, 9 and 10 Voltage will be approximately 32 V.
- If there is a short or open in a battery block voltage detection line, the value of Hybrid Battery Block Voltage for the corresponding battery block will be lower than 8 V.
