1. Disconnect the powertrain control module (PCM) connector C2.
2. Disconnect connector C310.
3. Use a J 35616-A in order to connect 1 red lead of a J 33431-C to cavity 1 of connector C310.
4. Connect the other lead to ground.
5. Turn the ignition switch to the ON position.
6. Set the resistance dial of the tester to the following values:

• | 120 Ohms

• | 32 Ohms

• | 3 Ohms

Does the fuel gauge read the specified values?

E (120 ohms)

1/2 (32 ohms)

F(3 ohms)

1. Disconnect the J 33431-C .
2. Disconnect the IP cluster assembly connector C3.
3. Connect a digital multimeter from the IP cluster assembly connector C3, cavity 9 to the fuel gauge sender unit connector cavity 1.
4. Measure the resistance.

Is the resistance more than the specified value?

5ohms
