Endeavor 2WD V6-3.8L SOHC (2006)
3. Measure the resistance between A/C-ECU connector C-16 <automatic air conditioning system> terminals 14 and 15.
OK: 1 kOhm or more
Q: Does the resistance measure 1 kOhm or more?
YES: <The resistance measures 1 kOhm or more> Diagnose CAN bus lines thoroughly by referring to DIAGNOSTIC ITEM 27: Diagnose CAN
bus lines thoroughly <Vehicles without ABS and vehicles with multi-center display (middle-grade type)>.
NO: <The resistance measures less than 1 kOhm> Replace the A/C-ECU.
Part 2
STEP 16. Check the CAN_L and H lines (communication lines including the SRS-ECU) between joint connector (4) and the SRS-ECU for short
circuit. Measure the resistance at joint connector (4) C-101.
CAUTION: A digital multimeter should be used.
CAUTION: The test wiring harness should be used.
1. Disconnect joint connector (4) C-101, and measure the resistance at the wiring harness side of joint connector (4) C-101.
2. Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION: Disconnect the negative battery terminal.
3. Disconnect the negative battery terminal.
4. Measure the resistance between joint connector (4) terminals 3 and 14.
OK: 1 kOhm or more
Q: Does the resistance measure 1 kOhm or more?
YES: <The resistance measures 1 kOhm or more> Go to Step 20.
NO: <The resistance measures less than 1 kOhm> Go to Step 17.
