.
- CHECK HARNESS AND CONNECTOR (PRE-COLLISION SYSTEM CANCEL SWITCH ASSEMBLY - DRIVING SUPPORT ECU ASSEMBLY)
- Disconnect the K1 pre-collision system cancel switch assembly connector.
- Disconnect the H75 driving support ECU assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition K1-1 - H75-5 (PBSW) Always Below 1 Ω K1-1 or H75-5 (PBSW) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
