DDM-52

DDM-52-BATTERY VOLTS LOW





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
At all times.

- Set Condition:
Anytime the module senses voltage input less than 9.0 volts but greater than 2.0 volts, this code will set.





Diagnostic Test

1. CHECK ENGINE DTC's
With the scan tool, read ENGINE DTC's
Are there any ENGINE DTC's present?

No

- Go To 2

Yes

- Diagnose and repair the DTC(s).

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 DDM-52-BATTERY VOLTS 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 the BODY VERIFICATION TEST - VER 1. Body Verification Test.

3. (A215) FUSED B(+) CIRCUIT RESISTED




NOTE: Ensure IPM Fuse #47 is good before proceeding.

Disconnect the Driver Door Module C1 connector.
Measure the voltage between the (A215) Fused B(+) circuit and Ground.
Is the voltage greater than 11.5 volts?

Yes

- Go To 4

No

- Repair the (A215) Fused B(+) circuit for high resistance.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

4. (Z821) GROUND CIRCUIT RESISTED




Using a 12-volt test light connected to 12-volts, test the (Z821) Ground circuit in the C1 connector
Does the test light illuminate brightly?

Yes

- Replace the Driver Door Module.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Repair the (Z821) Ground circuit for high resistance.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.
