1989 Rear Axle and Gear Identification

The code to identify your axle gear is located on the front face of the right hand axle tube about three inches from the differential cover.

Number Decode

A typical code could be 6HQ 0 103 2 - The initial number and next two letters (6HQ) indicate the axle code, here a 1989 Posi with a 3.23 axle ratio. The next number or letter (0) identifies the manufacturer, the next three digit number (103) indicates the date of manufacture, and the final digit (2) indicates the shift that this rear was produced.

1989 Computer (ECM) Trouble Codes

There is a way to read the codes by counting the flashes, but I would recommend simply going to some auto parts store and buying a GM code reader that plugs into your car. They are around $20.00

Code

Circuit or System

Probable Cause

12 No distributor reference pulse This code will flash whenever the diagnostic terminal is grounded with the ignition On and the engine not running. If additional trouble codes are stored, they will appear after this code has flashed three times.
13 Oxygen Sensor Circuit Sticking Throttle Position Sensor; Poor electrical connection; open or short circuit; defective oxygen sensor;defective ECM.
