VIN:
N52048 to N70068

Model Year:
2006

CONDITION SUMMARY:

"CHECK ENGINE" MIL "ON" WITH DTC P050B-84 OR P050B-85 STORED

Situation:
A customer may express a concern that the "Check Engine" amber warning lamp is illuminated. A cold-start emission DTC (P050B-84 or P050B-85) may be stored in the Engine Control Module (ECM).

An incorrect calibration between the cold start emission and engine coolant temperature may be the cause.

Action: Should a customer express a concern, and DTC P050B-84 or P050B-85 is stored, refer to the GTR Repair Procedure detailed in this bulletin to reconfigure the ECM using the Integrated Diagnostic System (IDS).

TOOLS:

IDS DVD43-Patch File 3 or DVD101 or later software.

WARRANTY:

NOTE:
Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only. Always refer to DDW to obtain the latest repair time.

DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.

Normal warranty policy and procedures apply.
