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.

INSPECTION PROCEDURE

NOTE:

Under certain atmospheric conditions, condensation, misting, and fogging is acceptable at any level providing it does not grow to the point where

water droplets form and run down the inside of the headlamp lens. Lamps which show misting or fogging will usually clear with no adverse effect

when the headlamps are switched 'ON'.

1. Inspect the headlamps for condensation, misting, and fogging.

^ If only condensation, misting, and fogging are evident, release the vehicle. (Figure 1)
