## Turn Signal/Hazard Flasher Control Circuit Input Test

1. | Remove the gauge assembly.

2. | Disconnect the 20P connector (A) from the gauge assembly (B).

3. | Make these input tests at the gauge 20P connector terminals. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, the turn signal/hazard relay must be faulty; replace it.
Cavity | Wire | Test condition | Test: Desired result | Possible cause if result is not obtained
--- | --- | --- | --- | ---
A19 | BLK | Under all conditions | Check for continuity to ground: There should be continuity. | Poor ground (G401) An open in the wire
A10 * A20 | GRN/WHT * BLK/WHT | Connect A10 and A20 terminals, then hazard warning switch ON | Check the hazard warning lights: Hazard warning lights should come on. | Poor ground (G201, G301, G401, G502) Faulty hazard warning switch An open in the wire
A10 | GRN/WHT | Ignition switch ON (II) | Check for voltage to ground: There should be battery voltage. | Blown No. 3 (7.5A) fuse in the under-dash fuse/relay box Faulty hazard warning switch An open in the wire
Hazard warning switch ON | Check for voltage to ground: There should be battery voltage. | Blown No. 14 (10A) fuse in the under-hood fuse/relay box Faulty hazard warning switch An open in the wire
