Title: No-ldle HVAC Run-Time Shorter than Expected - Bergstrom
Applies To: LT, HX Sleeper Models with 0016UZL or 0016VLN

DESCRIPTION

This document will guide the user through relocating the No-Idle system's voltage sense source from the battery to the interior sleeper PDM. This should only
be completed when the symptom of shorter than expected run-time of the no-idle system is present, and excess voltage drop is found across the battery

sense circuit

This rework will reduce the amount of voltage drop seen across the voltage sense circuit, which provides a more accurate voltage reading to the No-Idle

system controller.

DIAGNOSTIC STEP(s)

To prevent property damage, personal injury, and/or death, keep flames or sparks away
from the vehicle and do not smoke while servicing the vehicle's batteries. Batteries expel
lexplosive gases.

[To prevent property damage, personal injury, and/or death, remove the ground cable from the
negative terminal of the battery box before disconnecting any electrical components. Always
connect the ground cable last.

ry and/or death, always wear safe eye protection when

performing vehicle maintenanc:

[To prevent property damage, personal injury, and/or death, if the vehicle must be raised,
ldo not work under the vehicle supported only by jacks. Jacks can slip or fall over.

To prevent property damage, personal injury, and/or death, park the vehicle on a hard, flat

Isurface, turn the engine off, set the parking brake, and install wheel chocks to prevent the
vehicle from moving in either direction.

DIAGNOSTIC:
Measure the voltage drop of the No-Idle battery sense circuit.

(From Pin A9 at the No-idle system controller to B+ at the batteries)

Reference 1K0800523 - General Circuit Load Testing and Voltage Drop Test

Is voltage drop excessive?

lYes. Greater than 0.5v of voltage drop

Proceed to repair steps

No. Less than 0.5v of voltage drop

Refer to the appropriate service
manual for diagnostics
