| 22 | Indicates a fault in the coolant temperature sensor circuit. |
| 23 | Indicates a fault in the charge temperature sensor circuit. |
| 24 | Indicates a fault in the throttle position sensor circuit. |
| 25 | Indicates a fault in the AIS control circuit. |
| 26 | Indicates that peak injector current has not been reached. |
| 27 | Indicates internal problem in logic module fuel circuit. |
| 31 | Indicates an open or short in the canister purge solenoid circuit. |
| 32 | Indicates an open or short in the power loss lamp circuit. |
| 33 | Indicates an open or short in the air conditioning wide open throttle cut out relay circuit. |
| 34 | On 1983-84 models, indicates an open or short in EGR solenoid circuit. On 1985 models, indicates problem in spare driver circuit. |
| 35 | Indicates a problem in the fan relay circuit. |
| 36 | On 1985 models, indicates problem in spare driver circuit. |
| 37 | On 1985 models, indicates problem in shift indicator lamp circuit. |
| 41 | Indicates a fault in the charging system. |
| 42 | Indicates a fault in the ASD relay circuit. |
| 43 | Indicates a fault in the interface circuit. |
| 44 | On 1983-84 models, indicates internal failure in Logic Module. On 1985 models, indicates battery temperature is out of range. |
| 51 | On 1984 models, indicates a problem in the closed loop fuel system. On 1985 models, indicates oxygen sensor feedback system is latched lean. |
| 52 | On 1984 models, indicates internal failure in Logic Module. On 1985 models, indicates oxygen sensor feedback system is latched rich. |
| 53 | Indicates internal failure in Logic Module. |
| 55 | Indicates end of message. This will appear after all other codes have been displayed. |
| 88 | Indicates start of message. This will appear only on diagnostic readout tool No. C-4805 before any other codes are displayed. |
To call up codes, cycle ignition switch on, off, on, off and on within 5 seconds. Stored codes will be indicated by flashes of the power loss/check engine lamp. The codes will be indicated as two digit numbers, with a four second pause between codes. An example of a code is as follows:
- Power Loss/Check Engine Lamp illuminated for approximately 2 to 3 seconds as a bulb check, then turns off.
- Lamp flashes 2 times, pauses, then flashes 6 times.
- Lamp pauses for approximately 4 seconds.
- Lamp flashes 3 times, pauses, then flashes 1 time.
This would indicate that code 26 and 31 are stored. The lamp will continue to flash until all stored codes have been displayed.
Once the lamp starts flashing the stored fault codes, it cannot be stopped. If a code is missed, the entire procedure must be repeated. The lamp will not indicate if oxygen feedback system is switching lean-rich or if idle motor system is operational. The lamp also cannot be used to perform actuation test mode, sensor test mode or engine running test mode.
After all fault codes have been displayed, then power loss/check engine lamp can be used to verify switch function. The lamp will turn on and off as the switch is turned on and off.
