INSPECTION
Before performing diagnostics, check the following item which might affect body integrated unit malfunctions.
- Measure the battery voltage and check electrolyte. Standard voltage: 12 V or more Specific gravity: 1.260 or more
- Check the fuse condition. Make sure that ampere of the fuse is setting value, and it is not blown out.
- Check the connecting condition of harness and harness connector.
- Confirm settings of body integrated unit are corresponded to vehicle equipment. Ref. to «OPERATION»(ref-371881-S05166078522010091900000) , Registration Body Integrated Unit.
- Make sure that the User Customizing of the body integrated unit matches the vehicle equipment. Ref. to «OPERATION»(ref-371881-S37329733992010091900000) , User Customizing.
- Confirm "Factory or Market setting" of body integrated unit registrations is set to "Market".
- Confirm key illumination does not blink with ignition switch turned to ON.
BATTERY SHORT INSPECTION
Note. Main wiring harness or related lines may be shorted to battery circuit, or shorted to battery circuit in one of the control modules.
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS. Turn the ignition switch to ON. Using the tester, measure the voltage between terminals. Connector & terminal (B40) No. 6 - Chassis ground: (B40) No. 14 - Chassis ground | Is the resistance 5 V or less? | Currently returned to normal. | Go to step 2 . |
| 2 CHECK CONTROL MODULE. With the tester connected, disconnect control module. NOTE: Disconnect the body integrated unit at the end. Connector & terminal (B40) No. 6 - Chassis ground: (B40) No. 14 - Chassis ground | Did the voltage change to 5 V or less? | Replace the control module whose resistance has changed. When the value changed at disconnecting the body integrated unit, go to next. Go to step 3 . | Go to step 3 . |
| 3 CHECK BETWEEN MAIN WIRING HARNESSES. Using the tester, measure the resistance between terminals. Connector & terminal (i84) No. 27 - Chassis ground: (i84) No. 35 - Chassis ground | Is the voltage 1 V or less? | Replace the body integrated unit. Ref. to REMOVAL , Body Integrated Unit. | Repair or replace the short circuit of the harness. |
| NOTE |
|---|
| Disconnect the body integrated unit at the end. |
DIAGNOSTIC PROCEDURE CHART
Scheme 1

Connector & terminal (B40) No. 6 - Chassis ground: (B40) No. 14 - Chassis ground | Did the resistance change to 10 ohms or more? | Replace the control module whose resistance has changed. When the value changed at disconnecting the body integrated unit, go to next. Go to step 3 . | Repair or replace the short circuit of the harness. |
| 3 CHECK MAIN WIRING HARNESS AND RELATED LINES. Using the tester, measure the resistance between terminals. Connector & terminal (i84) No. 27 - Chassis ground: (i84) No. 35 - Chassis ground | Is the resistance 10 ohms, or less? | Repair or replace the short circuit of the harness. | Replace the body integrated unit. Ref. to REMOVAL , Body Integrated Unit. |
| 4 CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS. Turn the ignition switch to ON. Using the tester, measure the voltage between terminals. Connector & terminal (B40) No. 6 - Chassis ground: (B40) No. 14 - Chassis ground | Is the voltage 5 V or less? | CAN communication circuit is normal. | Go to step 5 . |
| 5 CHECK CONTROL MODULE. With the tester connected, disconnect control module. NOTE: Disconnect the body integrated unit at the end. Connector & terminal (B40) No. 6 - Chassis ground: (B40) No. 14 - Chassis ground | Did the voltage change to 5 V or less? | Replace the control module whose voltage has changed. When the value changed at disconnecting the body integrated unit, go to next. Go to step 6 . | Repair or replace the short circuit of the harness. |
| 6 CHECK HARNESS. Using a tester, measure the voltage between terminals and chassis ground. Connector & terminal (i84) No. 27 - Chassis ground: (i84) No. 35 - Chassis ground | Is the voltage 5 V or less? | Replace the body integrated unit. Ref. to REMOVAL , Body Integrated Unit. | Repair or replace the short circuit of the harness. |
| NOTE |
|---|
| Disconnect the body integrated unit at the end. |
