reading process
- Switch on ignition.
- Check the "O / D OFF" control lamp.
- Put the O / D switch on the selector lever in the ON position.
- Control lamp "O / D" OFF must go out.
- 1986-93: Outputs E1 and ECT of the diagnostic connection are bridged Fig.1.
- 1993-97: Outputs E1 and TE1 of the diagnostic connection bridge Fig.2 [1] or Fig.2 [2].
- If no error codes are set, the light flashes twice per second Fig. 3.
- Each error code consists of two groups, each with one or more blinking LEDs. Fig.4 [A].
- Flashing period. 0.5 seconds Fig. 4 [B].
- The individual flashing signals are separated by pauses of 0.5 seconds Fig.4 [C].
- The individual error code groups are separated by pauses of 1.5 seconds. Fig.4 [D].
- The individual error codes are separated by pauses of 2.5 seconds. Fig.4 [E].
- Example: Four flashes with a duration of 0.5 seconds - pause of 1.5 seconds - two flashes with a duration of 0.5 seconds. Error code 42 Fig. 4 - Forward speed sensor 1.
- The last error code is followed by a pause of 4.5 seconds. Thereafter, the stored error codes are repeated.
- Flashing signals of the indicator light count. Compare with error code table.
- Disconnect jumper cable.
- • Switch off the ignition.
- Fix displayed errors.
Deletion:
NOTE: The disconnect time of the fuse depends on the ambient temperature. The lower the temperature, the longer the fuse has to be removed.
- Switch off the ignition.
- 1986-88: Remove Bolt RAD No. 1 (15A).
- 1988-93: DOME (20 A) fuse removed from fuse box in engine compartment for at least 10 seconds Fig.5 [2].
- 1993-97: Remove fuse EFI No. 1 (30 A) from fuse box in engine compartment for at least 10 seconds Fig. 6.
- Reinstall the fuse.
- The deletion of the error code entries can also be done by disconnecting the battery cables.
ATTENTION: Disconnecting the battery can erase the memory contents of electronic components (eg radio and clock).
- Repeat the check procedure to ensure that all entries in the fault memory of the motor control unit are cleared.
