Circuit Description
This DTC is used to monitor the voltage level available to the cruise control module at terminal 9 (BLK/YEL wire).
Diagnostic Aids
Check for the following:
| • | Open or high resistance in the BLK/YEL wire. |
| • | Open, high resistance or low voltage in the power distribution to the ECU-IG fuse in junction block 2. |
| • | Open or high resistance in the WHT/BLK wire. |
| • | Open or high resistance in the ground distribution to splice pack 250/G203 |
| • | Vehicle charging system for poor performance. |
| • | 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 2 C4 |
| • | Splice pack 250 |
| • | Ignition switch |
Test Description
The number/description refers to the step in the diagnostic table.
