| B2A4C | Hybrid Battery Current Sensor Implausible (failed in range) | CLEAR the DTC.
|
| B2A4D | Battery Contactor Signal Incorrect After Event | REPAIR other DTCs first. TURN the ignition OFF. TURN the ignition to START, then off. WAIT 30 seconds. TURN the ignition switch on. RETRIEVE on-demand and continuous DTCs. If DTC B2A4D is retrieved, CHECK voltage output from the power sustain relay. With ignition ON/engine OFF, measure the voltage between the transaxle control module (TCM) 0517-101 pin 4, 0517-101 pin 5, circuit (W/O) harness side and ground. If voltage is less than 10 volts, REPAIR the circuit(s). REPEAT the self-test. TEST the system for normal operation. |
| B2172 | Inertia Switch Input Circuit Open | If the vehicle has a driveability and/or starting concerns (no start condition/poor engine performance), address these first. See the INTRODUCTION - HYBRID MODELS to continue diagnosis, then see PINPOINT TEST 5: DTC B2172 - INERTIA FUEL SHUTOFF (IFS) SWITCH INPUT CIRCUIT OPEN - HYBRID |
| B2950 | Air Conditioning System Fault | See PINPOINT TEST 17: DTC B2950 - AIR CONDITIONING SYSTEM FAULT, DTC P0535 - A/C EVAPORATOR TEMPERATURE SENSOR CIRCUIT FAILURE - HYBRID |
| C1862 | Contactor Circuit Failure | See PINPOINT TEST 3: DTC C1862 - CONTACTOR CIRCUIT FAILURE - HYBRID |

| P0A0A | High Voltage System Inter-Lock Circuit | See the INTRODUCTION - HYBRID MODELS to continue diagnosis. |
| P0A0C | High Voltage System Inter - Lock Circuit Low | CLEAR the DTC. REPEAT the on-demand self test. If DTC P0A0C is retrieved again, INSTALL a new HVTB. See HIGH-VOLTAGE TRACTION BATTERY REMOVAL/INSTALLATION - HYBRID . TEST the system for normal operation. |
| P0A0E
NOTE:
This DTC is set when the TBCM cannot determine if the front/rear IFS switches or the high-voltage system interlock circuit is the source of the intermittent fault.
|
High Voltage System Inter-Lock Circuit Intermittent | See PINPOINT TEST 6: DTC P0A0E - HIGH-VOLTAGE SYSTEM INTERLOCK CIRCUIT INTERMITTENT - HYBRID
NOTE:
An intermittent high-voltage system interlock circuit short or open circuit can cause DTC P0A0E to be set in continuous memory.
|
| P0A1F | Battery Energy Control Module | See PINPOINT TEST 8: DTC P0A1F - BATTERY ENERGY CONTROL MODULE HAS INTERNAL ERRORS - HYBRID |
| P0A27 | Hybrid Battery Power Off Circuit | If PCM DTC P0AE7 and TBCM DTC C1862 are also present, address them first, then see PINPOINT TEST 2: DTC P0A27 - HYBRID BATTERY POWER OFF CIRCUIT |
| P0A7D | Hybrid Battery Pack State of Charge Low | If the vehicle has a driveability and/or starting concerns (no start condition/hard start/poor engine performance), address these conditions first. Driveability and/or starting concerns may result in hybrid battery pack low state of charge and cause this DTC to be set. See the INTRODUCTION - HYBRID MODELS to continue diagnosis, then see PINPOINT TEST 9: DTC P0A7D - HYBRID BATTERY PACK STATE OF CHARGE LOW |
| P0A7E | Hybrid Battery Pack Over-Temperature | If any other DTCs are present, address them first. If only DTC P0A7E is the only DTC present, See PINPOINT TEST 13: DTC P0A7E - HYBRID BATTERY PACK OVER TEMPERATURE |
| P0A80 | Install a New Hybrid Battery Pack (End of Useful Life) | INSTALL a new HVTB. See HIGH-VOLTAGE TRACTION BATTERY REMOVAL/INSTALLATION - HYBRID
TEST the system for normal operation.
NOTE:
The customer may choose not to install a new battery pack due to the cost of replacement. If a new HVTB is not installed, the customer will experience reduced fuel economy and reduced power, which will eventually lead to a failure of the HVTB.
