Electronic Brake Control Module: Description and Operation
The ABS control unit computes the rear axle pinion rotating speed by reading the signal from the rear sensor unit. Then it supplies a DC current to theABS actuator. If any electrical malfunction is detected in the system, the ABS control unit causes the ABS warning lamp to turn on. In this condition, theABS system will be deactivated by the ABS control unit, and the vehicle's brake system reverts to normal operation.

APPLIED VEHICLE: 1998-99 Frontier (D22)
APPLIED DATE: See note under Service Information
APPLIED ENGINE #: KA24DE only
SERVICE INFORMATION
If the fuel gauge on a 1998-99 Frontier exhibits the symptoms listed below (indicated by bullet points), the cause may be wire harness to body groundcontact points, the fuel sender (in the fuel tank) or the unified control meter (contained in the speedometer assembly).
: NOTE
The wire harness to body ground and fuel sender conditions only apply to vehicles built before September 1, 1999. The unified control metercondition only applies to vehicles built before January 1, 1999.
^ Fuel gauge indicates less than full after the fuel tank is filled.
^ Fuel gauge moves down rapidly to 7/8 or 3/4 after the fuel tank is filled.
Use the following service procedure to repair the vehicle if these incidents occur.
SERVICE PROCEDURE
1. Confirm the incidents occur as described above.
A. If the incidents occur, proceed with step 2.
B. If the incidents do not occur, this bulletin does not apply.

2.
Remove the machine bolt from body ground M68 (located behind the passenger side kick panel) and clean the contact surfaces of the ground wireeyelet and the body panel as necessary to ensure metal-to-metal contact (see Figure 1). Reinstall the bolt carefully to avoid damaging the threads.

: NOTE
Do not over-tighten the machine bolt when reinstalling it.
3.
Remove the self-tapping screw from body ground M14 (located behind the driver's side kick panel) and clean the contact surfaces of the groundwire eyelet and body panel as necessary to ensure metal-to-metal contact (see Figure 2). Reinstall the screw carefully to avoid damaging thethreads.
: NOTE
If the body threads are stripped, install a slightly larger self-tapping screw to secure the body ground wire eyelet.
4. Replace the fuel sender located in the fuel tank.
: NOTE
The fuel sending unit can be accessed by either removing the fuel tank from the bottom of the vehicle or removing the truck bed from the top of thevehicle. Before removing the bed, make sure there is sufficient space around the vehicle to safely remove and store the bed. If the fuel tank isremoved, refer to the FE section in the appropriate service manual for instruction on removing the fuel tank/fuel sender.
: NOTE
The following step (step # 5) only applies to vehicles built before January 1, 1999.
5. Replace the speedometer assembly*. Refer to the BT section in the appropriate service manual.
* The speedometer assembly includes the unified control meter, which controls the fuel gauge, speedometer, engine temperature gauge, odometer andtachometer (it equipped).
: NOTE
Conform to local laws regarding speedometer/odometer replacement. A new speedometer/unified control meter with the odometer set to the correctmileage may be ordered as described in Claims Bulletin WB/98-017.

REPROGRAM INTERRUPTION RECOVERY PROCEDURE
SERVICE INFORMATION
A complete step-by-step General Procedure for CONSULT-III (C-III) ECM Reprogram Interruption Recovery is now available by attachment in thisbulletin.
While performing ECM (Engine Control Module) reprogramming, the reprogramming may stop (become interrupted) before it is 100% complete.
One of two messages may appear:
^ The VI probe is disconnected on USB, please check the connection of the probe.
^ Reprogramming fail, "Error code 0".
In many cases, reprogramming recovery is possible and the ECM may not need to be replaced if the complete ECM part number has been registered intothe ECM before reprogramming stopped.
NOTE:
ECM is referred to as ECU in C-III.
The ECM Reprogram Interruption Recovery General Procedure applies to Technical Service Bulletins that include ECM reprogramming published inApril 2010 and later.
IMPORTANT: BEFORE STARTING REPROGRAMMING
^ Connect a battery charger to the vehicle battery.
^ Be sure to turn OFF all vehicle electrical loads.
^ For ECM reprogramming, the C-III MUST be connected to the VI using the USB cable.
^ Be sure to connect the AC Adapter.
