Code No. B1107 Electric compressor input voltage (high)

DIAGNOSIS CODE SET CONDITIONS

This code is set when the overvoltage abnormality (high voltage of DC 425 V or more is detected for 3 seconds) judged by the A/C compressor inverter is detected.

PROBABLE CAUSES

Damaged harness wires and connectors
Malfunction of A/C compressor
Malfunction of the main battery

DIAGNOSIS PROCEDURE

STEP 1. Check the high-voltage connector and wiring harness.

danger

Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle. Refer to .

danger

Wear the specified protection equipment during the check.

1.Shut down the high voltage. (Refer to GROUP 00 - Precautions before Service - Precautions on handling high-voltage vehicle

.)
2.G-20 Check the A/C compressor connector.
3.Visually check the following high-voltage wiring harnesses for damage.

High-voltage wiring harness on main battery side
High-voltage wiring harness on A/C compressor side

Q. Is the check result normal?

	Go to Step 2.

	NO <Malfunction of connector and wiring harness on A/C compressor side> : Replace the A/C compressor.

	NO <Malfunction of wiring harness on main battery side> : Replace the main battery.

STEP 2. Check whether the diagnosis code is reset.

Q. Is the diagnosis code set?

	Go to Step 3.

	Intermittent malfunction. Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points, - How to Cope with Intermittent Malfunctions .)

STEP 3. After replacing the A/C compressor, check again if the diagnosis code is set.

Q. Is the diagnosis code set?

	Replace the main battery.

	This diagnosis is complete.
