Using blink codes, the technician may review all inactive

trouble codes stored on the ECU. The ABS indicator

lamp will display inactive diagnostic blink codes when the

diagnostic blink code switch is depressed and released two

times. See page 17 for the index showing trouble codes

and the troubleshooting guide page to read for help.

Inactive trouble codes, and event history, may be retrieved

and cleared by using a hand-held or PC-based diagnostic

tool, such as the Bendix

ACom

™

Diagnostics software.

Clearing Active Diagnostic Trouble Codes

The ECU will clear active trouble codes when the diagnostic

blink code switch is depressed and released three times.

System Conﬁ guration Check Mode

The ABS indicator lamp will display system conﬁ guration

information when the diagnostic blink code switch is

depressed and released four times. The lamp will blink

out conﬁ guration information codes using the following

patterns. (See Chart 3). In this mode the ECU tells the

technician, by means of a series of six blink codes, the type

of ABS system that the ECU has been set up to expect. For

example, if the fourth blink code is a three, the technician

knows that a 6S/5M sensor/modulator conﬁ guration has

been set.

Dynamometer Test Mode

The Dynamometer Test Mode is used to disable ATC when

needed (e.g. when performing any vehicle maintenance

where the wheels are lifted off the ground and moving,

including dyno testing). This mode is not reset by power

off, power on, cycling. Instead a hand-held or PC-based

diagnostic tool must be used to change the setting.

Alternatively, depressing and releasing the blink code

switch three times will cause the ECU to exit the blink

code mode.

Reconﬁ gure ECU Mode

Vehicle reconfiguration is carried out by using the

Reconﬁ gure ECU Mode. (See page 10.) Note: To enter

the Reconﬁ guration Mode, the blink code switch must be

held in before the application of ignition power. Once the

power is supplied, the switch is released and then pressed

seven times.
