INSPECTION PROCEDURE
| 1.CHECK CAN BUS LINE FOR OPEN (YAW RATE SENSOR BRANCH LINE) |
Turn the engine switch off.
Disconnect the yaw rate sensor connector (J41).
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection Condition Specified Value J41-3 (CANH) - J41-2 (CANL) Engine switch off 54 to 69 Ω
|
| ||||
| OK | |
| 2.CHECK WIRE HARNESS (IG, GND) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection Condition Specified Value J41-1 (GND) - Body ground Always Below 1 Ω
Measure the voltage according to the value(s) in the table below.
- Standard voltage:
Tester Connection Condition Specified Value J41-5 (IG) - Body ground Engine switch on (IG) 10 to 14 V
