### Circuit Description

When the EBTCM is operating in the traction control mode, the EBTCM will command the instrument cluster to turn ON the TRACTION ACTIVE indicator. This will alert the driver that the traction control system is operating.

### Diagnostic Aids

The following conditions may cause improper operation of the TRACTION ACTIVE indicator:

• | An open fuse

• | An open bulb

• | A malfunctioning EBTCM

• | A malfunctioning instrument cluster

Step | Action | Value(s) | Yes | No

1 | Was the ABS Diagnostic System Check performed? | -- | Go to Step 2 | Go to Diagnostic System Check
2 | Does the TRACTION ACTIVE indicator illuminate when the traction control is not active? | -- | Go to Step 6 | Go to Step 3
3 |

1. Turn the ignition switch to the OFF position.
2. Disconnect the EBTCM connector.
3. Connect the J 38716 pinout box.
4. Use the J 39200 in order to measure the resistance between the J 38716 terminal 1 and ground.

Is the resistance less than the specified value?

2 ohms

1. Connect a fused jumper from the J 38716 terminal 7 to terminal 1.
2. Turn the ignition switch to the RUN position.

Does the TRACTION ACTIVE indicator turn ON?

1. Turn the ignition switch to the OFF position.
2. Disconnect the J 38716 pinout box.
3. Reconnect all of the connectors.
4. Use the scan tool in order to select the ABS/TCS data list.

Monitor the TCS State.

5. Test drive the vehicle on a safe area under 40 km/h (25 mph). Drive on a slippery surface such as sand or gravel.

Does the TCS State change and did the TRACTION ACTIVE indicator turn ON during a traction control event?

--

Go to Diagnostic System Check

Go to Step 13

6 |

1. Turn the ignition switch to the OFF position.
2. Disconnect the EBTCM connector.
3. Turn the ignition switch to the RUN position.

Does the TRACTION ACTIVE indicator still turn on?

Go to Step 7

Go to Step 13

7 | Repair the short to ground in CKT 1656. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Diagnostic System Check | --
8 |

1. Turn the ignition switch to the OFF position.
2. Remove and check the TRACTION ACTIVE indicator bulb.

Is the bulb open?

Go to Step 12

Go to Step 9

9 |

1. Disconnect the remote telltale bank connector.
2. Turn the ignition switch to the RUN position.
3. Use the J 39200 in order to measure the voltage between the remote telltale bank harness connector terminal A1 and ground.

Is the voltage within the specified range?

Battery Voltage

Go to Step 11

Go to Step 10

10 |

1. Check for the following conditions:

• | CKT 39 for an open

• | IGN 1 Fuse for an open

• | remote telltale bank for the proper terminal contact

2. If the above conditions are OK, replace the remote telltale bank. Refer to Instrument Cluster Trim Panel Replacement in Instrument Panel, Gauges and Console.
