Conditions for Setting the DTC
A vehicle speed signal error occurs when the Control Module detects 5 or more transitions in the lateral accelerator switch input after 20 or more seconds without a vehicle speed input. If a fault is detected, the system will set error code 34 and activate the error lamp.
Actions Taken when the DTC Sets
- Record vehicle speed signal error.
- Turn on both of the driver select switch L.E.D.s.
The system will continue to default to zero speed damping level (Sport mode).

Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Is PCM code 24 set? | -- | Follow PCM diagnostics to repair | Go to Step 2 |
2 |
Is the resistance greater than 2 ohms? | ohms | Go to Step 3 | Go to Step 4 |
3 | Repair the open circuit condition in circuit 1298. Is the repair complete? | -- | -- | |
4 | Check circuit 1298 for a short circuit to ground condition by measuring the resistance between the wiring harness pin C7 and ground. Is the resistance greater than 100 ohms? | ohms | Go to Step 6 | Go to Step 5 |
5 | Repair the short circuit to ground condition in circuit 1298. Is the repair complete? | ohms | ||
6 | Check circuit 1298 for a short circuit to battery/ignition condition by measuring the resistance between the wiring harness pin C7 and circuit 50. Is the resistance greater than 100 ohms? | -- | Go to Step 7 | Go to Step 8 |
7 | Replace the control module. Refer to Electronic Suspension Control Module Replacement . Is the control module replacement complete? | -- | -- | |
8 | Repair short circuit to battery/ignition condition in circuit 1298. Is the repair complete? | -- | -- |
