Check the resistance with the body ground

(b) Check the resistance with the body ground.

(1) Disconnect connectors A and C and measure the resistance.

Standard resistance (Fig. 6)

HINT:

Measure the resistance while lightly shaking the wire harness vertically and horizontally. If your results match the examples above, an open circuit exists between terminal 1 of connector A and terminal 1 of connector C.

(2) Disconnect connector B and measure the resistance.

Disconnect connector B and measure the resistance

Standard resistance (Fig. 7)

If the results match the examples above, a short circuit exists between terminal 1 of connector B2 and terminal 1 of connector C.
