1998 Volvo Truck problems

What is wrong

Certain heavy duty class 8 vehicles fail to comply with federal motor vehicle safety standard no. 121, "air brake systems", s5.1.6.3, "antilock power for towed vehicles." electrical power for the trailer anti-lock braking system (ABS) can be disrupted when a switch located on the vehicle instrument panel is activated to control lighting within the trailer.

Risk

If this condition occurs, the driver can lose of the towed vehicle, possibly resulting in a vehicle crash.

Remedy

Dealers will install a wiring harness which will provide continuous electrical power to the trailer ABS whenever the ignition switch is in the on or run position. Owner notification began april 29, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact volvo trucks at 1‑800‑528‑6586.

Recall number 02V110000 · Recall details

What is wrong

Vehicle description: heavy duty trucks equipped with caterpillar 3116 mechanically unit injected diesel engines. The governor of the engine controls the unit injector fueling by way of a control assembly. In this assembly, a link to the governor is joined to the control rod using a rivet. This rivet can loosen and then wear resulting in engine speed instability.

Risk

If not identified and corrected, engine speed control could be lost due to rivet disengagement.

Remedy

Caterpillar is conducting the notification and remedy for this recall. Dealers will inspect the control assembly and replaced if necessary.

Odi's investigationconcluded that the legs that retain the turn signal canceling ring (tscr), part number 1607363, to the steering wheel installed in model year 1998 - 1999 vn and vhd series vtna (volvo truck north america) vehicles are prone to cracking and breaking.when the retention legs break, the separated pieces of the tscr typicallyrepose in the host cavity in the steering wheel hub where they were deposited.odifound that broken pieces of the tscr either (1) migrated from their host cavity and dropped completely from the steering wheel assembly or (2) lodged in various areas of the steering wheel proximate to the tscr.odi simulated various locations and positions that a separated piece of the tscr might become lodged within the steering wheel assembly, but none of these simulations generated any appreciable increase in steering effort.

Odi's preliminary evaluation focused on the potential for a broken, bent, deformed, fragmented or displaced turn signal canceling ring (tscr), vtna part number 1607363, to restrict thevehicle operator's ability to turn the steering wheel.the pe identified thirteen vtna warranty claims that allege that the tscr had failed and that the vehicle steering effort had been adversely affected.to date, odi has not found any samples of a failed tscr and has not been able to definitively establish whether a failed tscr can or cannot contribute to increased steering effort.odi believes that it is appropriate to conduct further investigation(ea level) to better understand the characteristics of tscr failures and to assess the effect, if any, that these types of failures could have on vehicle steering effort.
