! IMPORTANT: Geotab does not provide guidance for Hybrid, Electric vehicles.
! IMPORTANT: This HRN-CX10S4 harness will only work with IOX-KEYLESS H/W: B1 or later, as shown in the sample label below (available October 2021). It will not work with earlier versions of IOX-KEYLESS. If your device label does not indicate B1, please contact Geotab Support for further instructions.
Access the Geotab Keyless Start Inhibit installation document at this link: Geotab Keyless Starter Inhibit Overview and Installation for the HRN-CX10S4 Harness. NOTE: If IOX-KEYLESS is already installed the version number (and which Start Inhibit harness will work with it) can be determined via MyDecoder, by the IOX- codes as follows:
Keyless v2 - 0x15 = 21 (= HRN-CX09Y5)
Keyless V3 - 0x1D = 29 (i.e. B1 HW = HRN-CX10S4)
! IMPORTANT: The above guides show the NFC reader as a dash mount with a holder. However, for an IOX-KEYLESS installation, you must mount the NFC reader at the bottom corner of the windshield on the driver side, so the LED faces the windshield. Identify a location to bond NFC Reader to glass. The location must:
Clean the windshield area using an alcohol-based wipe. Clean the front of the IOX-NFCREADERA using an alcohol wipe and allow it to dry completely.
Route the NFC Reader in a way that:
Apply the referenced double-sided tape.
Prior to bonding NFC Reader to glass, ensure the following:
✱ NOTE: Use vehicle’s HVAC as needed to meet temperature specification or to help remove moisture.
! IMPORTANT: The double-sided adhesive tape is currently not included with the IOX-NFCREADERA shipping kit. If you do not receive the adhesive tape as a separate package with the main order, ask your Partner to order SKU SPR-ADHNFCFM (3M Dual Lock SJ3561 [Type 400] Adhesive).
✱ NOTE: An acceptable alternate source is 3M Dual Lock SJ3551 (Type 400).
If you opt to order your own, and the Dual Lock versions have long lead times, the third alternative is 3M VHB tape 5962, which is exceptional for most climates.
✱ NOTE: The VHB 5962 tape requires three layers to clear the strain relief hump.
Due to the transportation of dangerous goods act, the installer must supply the alcohol (70%) swipes.
