1998 GMC Jimmy Problems

ABS Light Due to Brake System Control Unit Failure

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

Check Engine Light With Code P1870

Vehicles equipped whit a 4 speed automatic transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.
