Brakes - Intermittent Flashing of the Pictogram

SEC. B-3 PG. 15
ISSUE: 06/88-1060
SUPERSEDES: 01/87-927
SUBJECT: INTERMITTENT FLASHING OF THE PICTOGRAM
APPLICATION: 9000 MODELS 1986-88
A service kit (M86-87), relay (M88) and repair procedure has been developed to correct the momentary flash of the pictogram that can occur when applying the brakes or using the turn signals. The service kit for 1986-87 models contains a relay which momentarily delays the signal to the pictogram display, allowing the circuits to stabilize. The relay for 1988 models replaces the stock relay and contains its own delay function. This service fix is not intended to compensate for an actual fault in the system that would result in a steady illumination of a failure indicator. In this case the wiring fault must be repaired before installing the service kit. See steps 8- 15 of this S.I.
Pictogram Service Kit M86-87 85-47-663
Pictogram Relay M88 95-64-139
Repair Procedure
1. Remove the glove compartment and fold down the relay panel.
M86-87 Models
Install the service kit P/N 85-47- 663 described in steps 2-6.
M88 Models
Remove the pictogram relay from the relay panel and replace with the new relay P/N 95-64-139. Proceed to step 6.
2. Locate the BR/VT (brown/white) wire (27B 0.5) which runs from terminal C1 of the filament monitor to terminal 1 of the pictogram.
FIGURE 1:
3. Cut the BR/VT cable and fit the two female terminals and insulation sleeves from the service kit to the two open ends (Figure 1).
4. Connect the wire from terminal no. 1 of the pictogram to terminal A on the delay relay. Connect the wire from terminal C1 of the pictogram relay to terminal B of the delay relay.
5. Drill a 4 mm hole at the edge of the relay panel (Figure 1) and mount the relay from the service kit using the nut and bolt. Be sure there is some slack in the wires.
6. Refit the relay panel and glove compartment and move on to the rear taillights.
7. Remove the plastic cover over the right taillight.
Check to see if the car has been previously modified (see S.I. 01/87- 927). If not, proceed to step 8.
FIGURE 2:
8. Cut the black wire (189A 1.0 M86/1.5 M87) at the right taillight as close to the harness sheathing as possible (Figure 2). Leave enough wire to reach the new ground point.
9. Attach a ring terminal to the black wire.
FIGURE 3:
10. Drill a hole in the body to accept a sheet metal screw, just below the taillight cluster (Figure 3). Carefully clean off all of the paint around the hole.
11. Attach the black wire with the ring terminal to the hole with a sheet metal screw. The regrounded right taillight should now be in a similar location as ground point 9 at the left taillight.
12. Refit the plastic cover over the taillight. Test drive the car. Observe the pictogram in the dash cluster while applying the brakes or using the turn signals.
NOTE
The service kit and grounding procedure above should correct a momentary flashing complaint. If a fault still exists, further inspection is necessary.
13. Remove all crimp connectors that may have been used in a previous attempt to fix a pictogram complaint. The taillight should be grounded directly to the car body as described in step 11.
FIGURE 4:
14. Inspect the taillight clusters. The clusters must be the correct ones for the car. Cluster plates should be marked for USA. The clusters are also marked for right (R) or left (L). Replace an incorrectly marked cluster (Figure 4).
15. Bulbs should be identified as being the correct one for the application. When replacing a bulb be sure to use bulbs of the same manufacturer in both sides. Using different brands of bulb may cause a resistance imbalance leading to a pictogram flash.
A bulb that has internal clouding or corrosion may also cause an imbalance, leading to a pictogram flash.
The clusters, lens, bulb contacts and electrical connections must be free of moisture and corrosion. Clean and repair as necessary using a recognized dielectric product.
