PINPOINT TEST 28: DTC P0AFA:16 OR P0AFB:17 - HYBRID

See the Tribute Wiring Diagram for schematic information.

Normal Operation

Under normal operation, the Air Conditioning Compressor Module (ACCM) receives hybrid battery system voltage through circuit (O/W). The ACCM is grounded through circuit (O/B).

- DTC P0AFA:16 (Hybrid Battery System Voltage Low: Circuit Voltage Below Threshold) - The module senses when hybrid battery system voltage is less than 165 volts.
- DTC P0AFB:17 (Hybrid Battery System Voltage High: Circuit Voltage Above Threshold) - The module senses when hybrid battery system voltage is greater than 450 volts.

Possible Causes
- Wiring, terminals or connectors
- ACCM

NOTE:Before carrying out the following test, diagnose any PCM DTCs.
