Specified Condition |
J140-3 (CNH1) - J28-18 (MSCH) |
Always | Below 1 Ω |
J140-4 (CNL1) - J28-19 (MSCL) |
Always | Below 1 Ω |
J140-3 (CNH1) - Body ground |
Always | 10 kΩ or higher |
J140-4 (CNL1) - Body ground |
Always | 10 kΩ or higher |
J140-3 (CNH1) - J140-4 (CNL1) |
Always | 10 kΩ or higher |
(d) Measure the voltage according to the value(s) in the table below. Standard Voltage:
Tester Connection | Condition |
Specified Condition |
J140-3 (CNH1) - Body ground |
Always | Below 1 V |
J140-4 (CNL1) - Body ground |
Always | Below 1 V |
NG |
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
OK |
