4.CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - COMBINATION METER ASSEMBLY)

Disconnect the I82 spiral cable sub-assembly connector.

Disconnect the I4 and I5 combination meter assembly connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
I82-11 (+DP) - I5-29 (MSM+)	Always	Below 1 Ω
I82-11 (+DP) or I5-29 (MSM+) - Body ground	Always	10 kΩ or higher
I82-10 (+DP2) - I5-12 (MSTI)	Always	Below 1 Ω
I82-10 (+DP2) or I5-12 (MSTI) - Body ground	Always	10 kΩ or higher
I4-2 (ES) - Body ground	Always	Below 1 Ω

Result:

Proceed to
OK
NG
