Troubleshooting Flowcharts

Diagnostic trouble code information can be retrieved from

the TABS-6 module by using blink code diagnostics, or a

diagnostic tool. The following troubleshooting ow charts

will help the technician isolate the cause of the fault and

conrm whether the fault resides in the component, wiring

or connectors.

Troubleshooting should always begin by observing the

dash or trailer-mounted ABS indicator lamp during the

TABS-6 module's power-up sequence. If it is necessary

to make electrical measurements, always begin by taking

voltage and resistance measurements at the 5 or 18-pin

ECU pigtail harness connector.

Once the circuit fault is found, isolate the area needing

repair by repeating the measurements at all connections

in the affected circuit towards the modulator, wheel speed

sensor, etc.

No voltage or resistance measurements are to be made on

the bulkhead connector pins of the module.
