Did you perform the Instrument Cluster Diagnostic System Check?

--

Go to Step 2

Go to Instrument Cluster System Check

1. Disconnect the ECT sensor connector.
2. Use a J 35616-A , and connect a RED lead of the J 33431-C to connector cavity 2 of the ECT.Connect the other lead to ground.
3. Turn the ignition switch to the ON position.
4. Set the resistance dial of the tester to the following settings:

•

136ohms

•

52ohms

•

10ohms

Does the ECT gauge indicate C at 136ohms, between the C and the H at 52ohms, and H at 10ohms?

Go to Step 3

Go to Step 4

Replace the sensor.

Is the repair complete?

Go to Instrument Cluster System Check

-

1. Disconnect the J 33431-C .
2. Disconnect the IP cluster assembly connector C1.
3. Connect a J 39200 from connector C1 terminal 6 of the instrument panel cluster to connector cavity 2 of the ECT sensor.
4. Measure the resistance.

Is the measured resistance less than the specified values?

5ohms

Go to Step 5

Go to Step 7

Inspect for high resistance in the printed circuit of the instrument panel cluster.

Is the circuit OK?

-

Go to Step 6

Go to Step 8

Replace the ECT gauge.

Is the repair complete?

-

Go to Instrument Cluster System Check

-

Repair the YEL/WHT wire between the instrument panel cluster and the ECT sensor. Refer to Wiring Repairs in Wiring Systems.
