Test 3

Checking for continuity in the harness

1.Turn the ignition key to the OFF position.

2.Check for continuity from

If there is continuity, proceed to Test 5.

If there is no continuity, proceed to Test 4.

1.Turn the ignition key to the OFF position.

2.Connect a jumper from harness connector pin A to a good ground.

3.Disconnect the J1B connector from the V-MAC II module.

4.Check for continuity from J1B connector pin L2 (the TPS voltage reference [+] line) to a good ground.

If there is continuity, proceed to Test 6.

If there is no continuity, try new ground points and retest. If there is still no continuity, locate and repair the open in the voltage reference [+] line (pin L2). Retest to be sure the problem has been corrected.
