Diagnostics

Hand-Held Testers

An OTC or MPSI hand-held tester may be used to read and clear fault

codes and to obtain a short description of failures. The tester can

initiate test sequences for controller outputs and can also read system

parameters.

Personal Computer-Based Diagnostics

Personal computer based software provides

the capability of hand-held testers with

enhanced display and data .ogging capability.

A personal computer can display multiple

parameters and provide more comprehensive

descriptions of fault conditions.

Use of a personal computer requires a serial link assembly such as Kent-

Moore’s part number J38351 and Spicer’s Tire Pressure Control System

diagnostic software.

Multimeter

Based upon system schematics and aided by component speciﬁc

fault codes, a multimeter can be used to check sensor and solenoid

resistances and to ﬁnd wiring harness faults. The multimeter can be used

to check the Tire Pressure Control System wiring and component for:

• continuity

• ground

• broken wires

• open circuits

• shorted circuits

• incorrect battery voltage
