1986 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 2HS 0 103 2 - The initial number and next two letters (2HS) indicate the axle code, here a 1986 Posi with a 3.73 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.

1986 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.
14 Coolant Temperature Sensor Circuit Engine overheating; poor electrical connection, open or short in circuit; defective coolant temperature sensor; defective ECM.
15 Coolant Temperature Sensor Circuit Poor electrical connection, open or short in circuit; defective coolant temperature sensor; defective ECM.

41-Carbureted Models No distributor reference pulses to ECM with engine running Poor electrical connection, open or short in circuit; defective distributor pick up coil; fault in the MAP or differential pressure sensor circuit.
41-Fuel Injected Models Cylinder Select error Incorrect or defective MEMCAL or ECM.
42 Electronic Spark Timing Poor electrical connection, open or short in circuit; defective ignition module; defective ECM.
43 Electronic Spark Timing Poor electrical connection, open or short in circuit; defective ESCmodule; defective knock sensor; defective ECM.
44 Lean Exhaust Lean condition caused by malfunctioning carburetor/fuel injector, vacuum leak, low fuel pressure, etc.; poor electrical connection, open or short in circuit; defective MAP sensor; defective oxygen sensor; defective ECM.
45 Rich Exhaust Rich condition caused by restricted air filter, fuel in evaporative charcoal canister or crankcase, malfunctioning carburetor/fuel injector, high fuel pressure, etc.; defective TPS; defective MAP sensor; defective oxygen sensor; defective ECM. 
46 Vehicle Anti-Theft System(VATS) Poor electrical connection, open or short in circuit; incorrect ignition key or starting procedure; defective VATS module; defective ECM.
