Determination Procedure
CAUTION:
- When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.
- When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.
- Disconnect the negative battery terminal before performing any work that requires handling of connectors.
DETERMINING SHORT TO POWER SUPPLY LOCATION (CAN-BUS No. 2) (US) DIAGNOSTIC PROCEDURE
| Step | Inspection | Action | |
|---|---|---|---|
| 1 | INSPECT BODY CONTROL MODULE (BCM) FOR SHORT TO POWER SUPPLY
|
Yes | Replace the body control module (BCM) because there is a short to the power supply in the body control module (BCM). (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION .) |
| No | Go to the next step. | ||
| 2 | INSPECT PCM FOR SHORT TO POWER SUPPLY
|
Yes | Replace the PCM because there is a short to the power supply in the PCM. (See PCM REMOVAL/INSTALLATION [(VIN M) (US)] .) (See PCM REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .) (See PCM REMOVAL/INSTALLATION [(VIN Y) (US)] .) |
| No | Go to the next step. | ||
| 3 | INSPECT DSC HU/CM FOR SHORT TO POWER SUPPLY
|
Yes | Replace the DSC HU/CM because there is a short to the power supply in the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D. (US)] .) |
| No | Repair or replace the wiring harness between the DSC HU/CM and body control module (BCM) and PCM because the wiring harness is shorted to the power supply. | ||
