The DIM has an internal battery voltage sensor and a reference voltage. The DIM compares these 2 voltages via the 2 battery positive voltage circuits every 300 milliseconds.
This DTC will run only if the DIM has power and ground. This DTC will execute regardless of the source voltage.
This code shall be set after 10 consecutive readings that the 2 battery positive voltages differ by 1 volt or greater.
All writes to the EEPROM will be suspended. All loss of communication and low/high voltage DTC codes are suspended.
• | A current DTC clears when the malfunction is no longer present. |
• | A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction. |

Is the voltage difference less than the specified value? | 1 V | Go to Step 5 | Go to Step 3 |
3 | Test both DIM battery positive voltage circuits for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 7 | Go to Step 4 |
4 | Test both DIM ground circuits for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 7 | Go to Step 5 |
5 | Inspect for poor connections and terminal tension at the harness connector of the DIM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 7 | Go to Step 6 |
