High-Altitude Kit "B"

INSTALLATION PROCEDURES FOR INDIVIDUAL KITS

2. HIGH ALTITUDE KIT B

2-1) Component parts





2-2) Installation procedure

NOTE: Numbers enclosed with a circle in the following explanation denote the parts shown in Figure 7.

1) Grounding wire and hoses





a) Tighten the grounding wire (1) with the bolt ("A" in Figure 8.) holding the vacuum switch bracket to the body.

NOTE: Make sure that the bolt is securely tightened.

b) Connect the connector ("B" in Figure 8.) at the opposite end of the grounding wire to the black single pole connector protruding from the body harness.

NOTE: Insert the connector until it is locked.

2) Replacement of EGR leak orifice





a) Remove the hose as shown (hatched) in Figure 9, and connect the hose (4 x 9) (2) (which contains an orifice) in the kit to the same position as the removed hose.

3) Checking and adjusting engine idling speed

Check to see that the engine idling speed is within specifications and adjust if necessary.

4) Affixing high-altitude label





a) On vehicles equipped with this high-altitude kit, affix the high-altitude label to the reverse side of the engine hood, at the position shown in Figure 10.

2-3) Function checking





After completion of the above procedure, check for high-altitude function according to the flow chart shown in Fig. 11.

2-4) High-altitude to low-altitude modification procedure

To return a vehicle modified to high-altitude specification by use of kit B, into low-altitude specifications, proceed as follows:

1) Remove the grounding wire. (See Figure 8.)

2) Replace the EGR leak orifice with low-altitude one (0.8 mm dia.). (See Figure 9.)

3) Check to see that the engine idling speed is within the specified range and adjust if necessary.

700 +/- 100 rpm at neutral position

4) Remove the high-altitude label from the reverse side of the engine hood. (See Figure 10.)

5) Check for low-altitude function in the same manner as described 2-3). However, the trouble code "11" in Figure 11 should read "12".
