For 1990-2009 cars

### Circuit Description

This DTC checks for an abnormal VSS input to the cruise control module or a malfunction within the cruise control module.

### Diagnostic Aids

Check for the following:

• | DTCs in the powertrain control module

• | If the speedometer operates normally, the VSS is OK

• | Open or high resistance in the PPL/WHT wire between junction block 3 and the cruise control module

• | Faulty cruise control module

An intermittent may be caused by a poor connection, rubbed through wire insulation or a wire broken inside the insulation. Inspect the following harness connectors for backed out terminals, improper mating, broken lock, improperly formed or damaged terminals or for poor terminal-to-wire connection before replacing the suspect component:

• | Cruise control module connector

• | Junction block 3 C1

• | C210

### Test Description

The number below refers to the step number on the diagnostic table.

3. Remove the ECU-B fuse.
4. Wait 30 seconds.
5. Reinstall STOP and ECU-B fuses.
6. Turn ON the ignition, with the engine OFF.
7. Using the jumper, connect the DLC terminals Tc and E1.
