Test G: DTC: B1676 - Battery Voltage Out Of Range
PINPOINT TEST G: DTC: B1676 - BATTERY VOLTAGE OUT OF RANGENormal Operation
Under normal operation, the HVAC module - electronic automatic temperature control (EATC) or HVAC module - dual automatic temperature control (DATC) module receives a ground through circuit GD116 (BK/VT). The HVAC module - EATC or HVAC module - DATC is supplied constant battery voltage through circuit SBP07 (WH/RD) and ignition switched voltage through circuit CBP20 (YE/VT).
- DTC B1676 Battery Voltage Out of Range - The module senses when battery voltage is less than 9 volts or greater than 16 volts.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- HVAC module - EATC module
- HVAC module - DATC module
