Sidekick JS 2D Soft Top 2WD L4-1.6L (1997)
INSPECTION PROCEDURE
CIRCUIT DESCRIPTION:
Ignition voltage is supplied through terminal "2" of the Antilock Brake System (ABS) enable relay. Then the Electronic Brake Control Module
(EBCM) is able to energize the pull-in coil by completing the ground circuit at pin "22" of the EBCM. The magnetic field created closes the ABS
enable relay contacts and allows battery voltage and current to be supplied to the EBCM, which supplies power to the motors and solenoids.
FAILURE CONDITION:
DTC14 can be set any time after the EBCM commands the ABS enable relay on (the relay is first commanded on during initialization). This test
monitors the availability of current/voltage to the motors and solenoids. This malfunction indicates voltage is not available and would therefore not
allow ABS operation if required.
DIAGNOSTIC AIDS:
An "intermittent" malfunction may be caused by a poor connection, rubbed through wire insulation or a wire that is broken inside the insulation.
The frequency of the malfunction can be checked by using the enhanced diagnostic-function of the TECH-1 as described in "Enhanced Diagnostics".
Any circuitry that is suspected of causing the intermittent malfunction should be thoroughly checked for backed out terminals, improper mating,
broken locks, improperly formed Undamaged terminals, poor terminal-to-wiring connections or physical damage to the wiring harness.
VIBRATION AND TEMPERATURE EFFECTS:
Check for vibration effects by performing the relay test function of the TECH-1. With the relay commanded on, lightly tap the top and sides of the
relay while monitoring relay voltage. If the relay voltage changes significantly, replace the relay.
If DTC 14 only occurs when the vehicle is initially started in cold ambient conditions (temperature less than 0°C [32°F]), replace the relay.
DTC 15 - ABS Enable Relay Circuit Shorted Or Closed
