How to test Delphi systems ECM codes (00-03)

[pilot1996]

Submitted by TCSTD: 1. Remove right side saddlebag and side cover if so equipped. Remove protective plug from data link connector. 2. To activate the diagnostic feature, proceed as follows: a. Create diagnostic test wire or use a female spade clip. b. Install diagnostic test wire across Terminals 1 and 2 on the data link connector. c. Turn Ignition/Light Key Switch to IGNITION and wait approximately 10 seconds (4 seconds lamp ON, 6 seconds lamp OFF) for check engine lamp to start flashing. 3. All trouble codes are sent out as a series of flashes. To retrieve the first digit of the trouble code simply observe the number of times the lamp flashes. a. The lamp will then flash one or more times to indicate the first digit of the trouble code. b. The length of time the lamp is illuminated and the length of time in which it is off are each about 0.5 second in duration. 4. The second digit follows: a. Following the transmission of the first digit, there is a 1.2 second pause in which the lamp is off. b. The lamp will then flash one or more times to indicate the second digit of the trouble code. Count the number of times the lamp flashes to retrieve the second digit. 5. If more than one trouble code is sent: a. Following transmission of the second digit of the first code, there is a 3 second pause in which the lamp is off. b. Once all codes have been sent, the data string is repeated. When you have recorded the same trouble code twice, it is an indication that the transmission has been restarted and that all trouble codes have been retrieved. IMPORTANT NOTE ..If diagnostic test wire is installed across Pins 1 and 2 on connector in lieu of a Scanalyzer, the ECM is placed in a diagnostic test mode and the engine will start. The test wire must be removed from the data connector and the ignition switch turned OFF or the check engine lamp will continue to flash codes. A historic trouble code resides in the memory of the ECM until the code is cleared by use of the Scanalyzer or a total of 50 trips has elapsed. A “trip� consists of a start and run cycle, the run cycle lasting at least 30 seconds. After the 50 trip retention period, the trouble code is automatically erased from memory (that is, assuming no subsequent faults of the same type are detected in that period). The numbers after the 'historic' or 'current' is the speedo code number, but without the electrical diognostics manual you're peeing into the wind. 1 Current 53 ECM flash error 2 Historic 53 ECM flash error 3 Current 54 ECM EEPROM error 4 Historic 54 ECM EEPROM error 5 Current 63 ECM serial data low 6 Current 63 ECM serial data open/high 7 Current 63 TSSM serial data low 8 Current 63 TSSM serial data open/high 9 Current 61 Loss of TSM/TSSM serial data 10 Current 14 Loss of all ECM serial data (state of health) 10 24 Loss of vehicle speed 10 33 Loss of vehicle inhibit motion 10 43 Loss of power train security status 11 Current 33 System relay contacts open 12 Current 33 System relay coil high/shorted 13 Current 33 System relay coil open/low 14 Current 33 System relay contacts closed 15 Current 99 Incorrect password 16 Current 99 Missing password 17 Current 41 CKP sensor intermittent 18 Current 41 CKP sensor synch error 19 Current 11 TP sensor open/low 20 Current 11 TP sensor high 21 Current 12 MAP sensor open/low 22 Current 12 MAP sensor high 23 Current 14 ET sensor voltage low 24 Current 14 ET sensor open/high 25 Current 15 IAT sensor voltage low 26 Current 15 IAT sensor open/high 27 Current 24 Front ignition coil open/low 28 Current 25 Rear ignition coil open/low 29 Current 24 Front ignition coil high/shorted 30 Current 25 Rear ignition coil high/shorted 31 Current 24 Front cylinder combustion intermittent 32 Current 25 Rear cylinder combustion intermittent 33 Current 23
