*a Front view of wire harness connector
(to Millimeter Wave Radar Sensor Assembly) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition B9-3 (CA2H) - B9-2 (CA2L) Cable disconnected from negative (-) auxiliary battery terminal 54 to 69 Ω Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE CAN BRANCH WIRE OR CONNECTOR
Result:
OK
See step 2
- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition B9-1 (SGND) - Body ground Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω *a Front view of wire harness connector
(to Millimeter Wave Radar Sensor Assembly) - Reconnect the cable to the negative (-) auxiliary battery terminal.NOTE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
