1. Disconnect driver's seat belt switch connector F-18 and measure the resistance available at the wiring harness side of the connector.
2. Measure the resistance value between terminal 1 and ground.
-
The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES: Go to Step 5.
NO: Go to Step 4.
STEP 4. Check the wiring harness between driver's seat belt switch connector F-18 (terminal 1) and ground.
Q: Is the wiring harness between driver's seat belt switch connector F-18 (terminal 1) and ground in good condition?
YES: No action is necessary and testing is complete.
NO: The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the
connector. Repair the wiring harness as necessary. If the functions, which are described in "CIRCUIT OPERATION", work normally, the input signal
from the driver's seat belt switch should be normal.
