For 1990-2009 cars

Step | Action | Values | Yes | No
--- | --- | --- | --- | ---
1 | Did you perform the Instrument Cluster System Check? | -- | Go to Step 2 | Go to Instrument Cluster System Check
2 | Inspect the front brake lining and sensors for wear, damage to sensors, and sensor wire chafing. Did you find and repair a problem? | -- | Go to Step 9 | Go to Step 3
3 |

1. Disconnect both the left and the right sensors.
2. Use a DMM and measure the resistance across both sensor terminals.

Is the resistance reading within the specified value?

OL

Go to Step 4

Go to Step 5

4 | Replace the sensors that failed the resistance test. Is the replacement complete? | -- | Go to Instrument Cluster System Check | --
5 |

1. Locate the right brake pad wear sensor connector
2. Connect one lead from the DMM to cavity 3 of the connector (harness side, BLK wire).
3. Connect the other lead to a good ground.
4. Measure the resistance.

Is the resistance reading within the specified value?

0-2 ohms

Go to Step 6

Go to Step 7

6 | Test for an open circuit in CKTs BA2 or BA3. Did you find and repair an open in CKTs BA2 or BA3? | -- | Go to Step 9 | Go to Step 8
7 | Locate and repair the open ground circuit. Is the circuit repair complete? | -- | Go to Step 9 | --
8 | Replace the gauge cluster. Is the replacement complete? | -- | Go to Instrument Cluster System Check | --
9 | Verify brake pad wear indicator operation:

1. Disconnect one of the brake pad wear sensor connectors.
2. Observe the brake pad wear indicator lamp on the gauge cluster.

Is the indicator lamp ON?
