B210D-BATTERY VOLTAGE LOW
For a complete wiring diagram Refer to Section 8W.
- When Monitored:
When a power opening or closing operation is not occurring.
- Set Condition:
Anytime the Power Liftgate Module senses voltage input below 9.5 volts when a power opening or closing operation is not occurring, this code will set.
| POSSIBLE CAUSES |
| LOW BATTERY VOLTAGE |
| CHARGING SYSTEM FAILURE |
| (A115) FUSED B(+) OR (Z125) GROUND CIRCUIT OPEN OR HIGH RESISTANCE |
| POWER LIFTGATE MODULE |
Diagnostic Test
1. CHECK ENGINE DTC'sNOTE: Ensure the battery is fully charged before proceeding.
With the scan tool, read ENGINE DTC's
Are there any BATTERY OR CHARGING SYSTEM DTC's?
No
- Go to 2
Yes
- Refer to symptom list for problems related to ENGINE.
2. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase DTC's
Start the engine and run for 2 minutes.
With the scan tool, read DTC's.
Does the scan tool display B210D-BATTERY VOLTAGE LOW?
Yes
- Go To 3
No
- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
3. CHECK THE (A115) FUSED B(+) AND THE (Z125) GROUND CIRCUITS FOR AN OPEN OR HIGH RESISTANCE
Disconnect the Power Liftgate Module C3 harness connector
Test for an open or high resistance on the (A115) Fused B(+) circuit by connecting a 12-volt test light between the (A115) Fused B(+) circuit and the (Z125) Ground circuit in the Power Liftgate Module harness C3 harness connector. The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
Does the test light illuminate brightly?
Yes
- Replace the Power Liftgate Module in accordance with Service Information.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
No
- Repair the (A115) Fused B(+) or the (Z125) Ground circuit for an open or high resistance.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
