OUTPUT OF DIAGNOSTIC CODESTo obtain an output of diagnostic codes, proceed as follow:
1. Initial conditions
(a) Battery voltage 11 V or more
(b) Throttle valve fully closed (throttle position sensor IDL points closed)
(c) Transmission in neutral range
(d) Accessories switched OFF
(e) Engine at normal operating temperature
2. Turn the ignition switch ON. Do not start the engine.
3. Using SST 09843-18020,connect terminals TE1 and E1 of the data link connector 1.
4. Read the diagnostic code as indicated by the number of flashes of the malfunction indicator lamp.
California Models:
Non California Models:
(a) Normal System Operation (no malfunction).
- The light will alternately blink ON and OFF approx. 2 times per second.
California Models:
Non California Models:
(b) Malfunction Code Indication.
- In the event of a malfunction, the light will blink every 0.5 seconds (0.52 seconds). The first number of blinks will equal the first digit of a 2-digit diagnostic code and, after a 1.5 second pause, the 2nd number of blinks will equal the 2nd. If there are two or more codes, there will be a 2.5 second pause between each.
- After all the codes have been signaled, there will be a 4.5-second pause and they will all be repeated as long as the terminals TE1 and E1 of the data link connector 1 are connected.
HINT: In the event of a number of trouble codes, indication will begin from the smaller value and continue to the larger in order.
(c) 2 trip detection logic Indication.
Diagnostic codes 21, 25, 26 and 71 use "2 trip detection logic". With this logic, when a malfunction is first detected, the malfunction is temporarily stored in the ECM memory. If the same case is detected again during the second drive test, this second detection causes the malfunction indicator lamp to light up.
The 2 trip repeats the same mode a 2nd time. (However, the ignition switch must be turned OFF between the 1st time and 2nd time).
5. After the diagnostic check, remove the SST 09843-18020.
