SAFETY RECALL V1801

BRAKE SWITCH INSPECTION

 

AFFECTED VEHICLES 

• 2018MY Isuzu NPR Vehicles with 4JJ1 Diesel engines
• 2019MY Isuzu NPRHD, NPRXD Vehicles with 4HK1 Diesel Engines

See the attached VIN list.

 

INFORMATION

CONDITION

The affected vehicles were equipped with a new brake switch and nylon retainer. In production, the brake switch retainer tabs may not have been fully secured into the steel brake pedal assembly bracket. An unsecured tab could allow the switch and retainer to detach from the bracket. If the switch and retainer become detached, the brake lights will illuminate whether or not the brake pedal is depressed, the shift interlock will not operate and the accelerator pedal input will be disabled, causing the vehicle to lose power and increasing the risk of a crash.

 

CORRECTION

Isuzu dealers are to inspect and, if necessary, replace the retainer clip to address this concern. This service will be performed free of charge.

 

VEHICLES INVOLVED

Involved are a limited number of Model Year 2018 NPR vehicles with 4JJ1 Diesel engines and 2019 NPRHD, NPRXD (4HK1) Isuzu N-Series vehicles with 4HK1 Diesel engines.  See the attached VIN list.

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Isuzu Vehicle Inquiry System (IVIS).

For dealers with involved vehicles, a report of involved vehicles containing the complete vehicle identification number has been or will be provided. Dealers will not have a report available if they have no involved vehicles currently assigned. 

 

PARTS INFORMATION

Dealers with affected vehicles will be shipped replacement retainer clips in order to complete any necessary repairs at no charge. Dealers may submit for a claim for parts mark-up reimbursement as a sublet allowance. See Claim Information for details.

 

SERVICE PROCEDURE 

1. Locate the brake switch on the front of the brake pedal bracket. (See Figure 1) The brake switch is installed into the retainer clip (See Figure 2) which is installed onto a flat metal plate on the brake pedal bracket. Ensure to properly illuminate the area with a drop light.

Figure 1	Figure 2

 

2. Push the brake switch towards the passenger side and then towards the driver side (See Figure 3) to determine if the retainer clip lifts up and forms a gap on either side from the flat metal plate (See Figure 4).

a. If the retainer clip does not lift up and form a gap, then the clip is fully seated and the campaign is complete. Proceed to the “Applying the Campaign Label” section.

b. If the retainer clip does lift up and form a gap on either side, proceed to Step 3.

Figure 3	Figure 4

 

3. Remove the brake switch by turning it counter-clockwise until it stops, then pulling it straight out. (See Figures 5 and 6).

Note: There is no need to disconnect the electrical connector.

Figure 5	Figure 6

 

4. Push inward on the retainer clip with a fingertip – an audible click may be heard.
5. Reinstall the brake switch by inserting the switch into the retainer clip opening, then push inward until the tip of the threaded portion of the switch makes contact with the pedal side bracket. This will depress the brake switch, but not the brake pedal. Rotate the switch clockwise approximately 45° while contact is being made.

Note: Make sure NOT to depress the pedal with the switch when it makes full contact.

A gap (1.2 to 2.3 mm) between the tip of the threaded portion of the switch and the pedal side bracket will be made automatically when the switch is locked into place by turning. (See Figure 7) This gap is the correct brake switch adjustment.

Figure 7

 

6. Repeat Step 2 to determine if the retainer clip lifts to form a gap. (See Figures 3 and 4)
   1. If the retainer clip does not lift up and form a gap, then the clip is fully seated and the campaign is complete. Proceed to the “Applying the Campaign Label” section.
   2. If the retainer clip does lift up and form a gap, proceed to Step 7.
7. Remove the two (2) accelerator pedal position sensor assembly nuts and set the assembly off to the side with the electrical connector still connected. (See Figures 8 and 9)

Figure 8	Figure 9

 

8. Remove the brake switch as outlined in Step 3.
9. Using a flat-head screwdriver, break off the top round flange of the retainer clip to allow the complete removal of the clip. (See Figures 10 and 11) Carefully inspect the entire area to ensure that any broken pieces of the clip are completely removed and discarded.

Figure 10	Figure 11

 

10. Install the new retainer clip by pushing it firmly in place with a fingertip – an audible click should be heard.
11. Reinstall the brake switch as outlined in Step 5.
12. Repeat Step 2 to determine if the retainer clip lifts to form a gap. (See Figures 3 and 4) If the retainer clip is still lifting to form a gap, repeat Steps 8 through 11.
13. Reinstall the accelerator pedal position sensor assembly with the two (2) nuts removed in Step 7. Ensure that the position sensor arm is correctly located in the opening in the bottom of the accelerator pedal. (See Figure 12)

STOP SALE AND DELIVERY – SAFETY RECALL

Date:  April 4, 2018

Subject: Stop Sale and Delivery for Upcoming Safety Recall

Affected Models: See Attached VIN List

To: Isuzu Dealer Principal, Sales Manager and Service Manager

Effective immediately, stop the delivery of the above vehicles in your inventory.  Isuzu is in the process of taking steps to address a safety-related defect in these vehicles.  Federal law prohibits the sale and delivery to customers of any vehicle containing a safety defect.  You must not deliver any covered vehicles to customers until after the vehicle has been remedied.

 

WHAT IS THE CONDITION?

The affected vehicles were equipped with a new brake switch and nylon retainer.  In production, the brake switch retainer tabs may not have been fully secured into the steel brake pedal assembly bracket.  An unsecured tab could allow the switch and retainer to detach from the bracket.  If the switch and retainer become detached, the brake lights will illuminate whether or not the brake pedal is depressed, the shift interlock will not operate and the accelerator pedal input will be disabled, causing the vehicle to lose power and increasing the risk of a crash.

 

WHAT WE WILL DO

In the near future, Isuzu will (1) send you replacement retainer clips and (2) release a campaign bulletin with more information and claim submission details.

 

WHAT YOU SHOULD DO

For affected vehicles in dealer inventory, open a repair order referencing this Stop Sale and perform the following inspection to determine whether the retainer clip is or is not properly seated and whether it needs to be replaced.  If the clip requires replacing, hold the vehicle until the replacement part is received and can be installed.

 

INSPECTION

1. Push the brake switch towards the passenger side and then towards the driver side. If the nylon retainer lifts up on either side try to re-seat it.  To re-seat the retainer, remove the brake switch, and then apply downward force to the retainer by hand.  An audible click may be heard.
2. Reinstall and adjust the brake switch as per the appropriate Service Manual. Repeat the previous step.  This time in addition to pushing, also pull up on the switch.  If the retainer lifts up again or the brake switch and retainer come out altogether, the retainer must be replaced.
   1. If the retaining clip is successfully re-seated, the vehicle has been corrected and may be released for sale. Apply a campaign label indicating the recall inspection and re-seating were completed (referencing labor code V1801) and submit a campaign claim in accordance with the campaign bulletin to be released in the near future.
   2. If the retainer clip cannot be properly re-seated, it must be replaced. In that case, you must hold the vehicle until you (a) receive a replacement retainer clip and (b) repair the vehicle in accordance with the campaign bulletin to be released in the near future.

We regret any inconvenience which this action may cause you.

Sincerely,

Isuzu Commercial Truck of America, Inc.
